Understanding Lawn Mower Batteries

Lawnmowers can be categorized into two main types based on their operation—push mowers and riding mowers—each requiring different power sources:

 

Push Lawn Mowers: These are usually powered by electricity (corded), rechargeable batteries (cordless), or gasoline.

Riding Lawn Mowers: These larger models resemble small vehicles and typically use more substantial batteries to power their more demanding engines and additional features such as lighting and electronic starters.

Voltage Specifications of Lawn Mower Batteries

The voltage of a lawn mower battery can determine both the efficiency of power delivery and the compatibility with the mower’s motor. Here’s what you need to know:

 

12-Volt Batteries in Riding Mowers: Similar to automotive batteries, 12-volt batteries in riding lawn mowers are common. They provide sufficient power for starting the engine and powering basic electrical components.

Higher Voltage Batteries in Push Mowers: Modern battery-operated push mowers often use higher voltages, such as 36 or 40 volts, provided by lithium-ion batteries. These provide a higher energy density, which enhances the mower’s run time and power output without the need for frequent recharging.

Benefits of Using 12-Volt Batteries

12-volt batteries are particularly favored for their reliability and ease of maintenance, especially in riding lawn mowers:

 

Accessibility: 12-volt batteries are readily available and can be replaced easily, similar to car batteries.

Cost-Effectiveness: They are generally more affordable compared to specialized or higher voltage batteries.

How to properly maintain UPS lithium battery during use?

ups-system

If the UPS lithium-ion battery is not used and maintained in the correct way, the life of the battery will be shortened. Therefore, on the basis of selecting a regular standard battery, the battery must be properly protected and used.

To ensure the normal operation of UPS lithium-ion battery. We recommended to maintain the lithium battery UPS power system from the following aspects.

Pay attention to various parameters of the UPS

When using a UPS lithium battery, you should pay attention to various parameters of the UPS, such as input voltage range, output waveform, output power, power supply time and conversion time. What’s more, lithium battery brand, machine noise, volume, weight and other parameters. All kinds of UPS are not suitable for working at full load. More than 20% of the power margin should be reserved, and the load should be controlled between 40% and 60% of the rated output power of the UPS.

Proper discharge

When the UPS lithium battery is not used for a long time. We recommended to turn it on every one month and let the UPS be in the inverter working state for at least 2 to 3 minutes in order to activate the battery and extend the service life of the battery. When charging, over-current and over-voltage charging should be avoided as much as possible. Proper discharge helps activate the battery.

Maintain a suitable ambient temperature

An important factor affecting the life of UPS lithium battery is the ambient temperature. Generally, the optimal ambient temperature required by battery manufacturers is between 20-25°C. Once the ambient temperature exceeds 25°C, the battery life will be shortened by half for every 10°C increase.

Replace damaged batteries promptly

In the continuous operation and use of UPS lithium battery, due to differences in performance and quality, it is inevitable that the performance of individual batteries will decline and the storage capacity will not meet the requirements and be damaged. When certain batteries/batteries in the battery pack are damaged, maintenance personnel should inspect and test each battery to eliminate damaged batteries.

Lithium-ion battery

Do not frequently turn off and on the UPS lithium battery power supply

Generally, the UPS power supply must be turned off for 6 seconds before it can be turned on again. Otherwise, the UPS power supply may be in a “start-up failure” state.  In other words, the UPS power supply is in a state where there is neither mains output nor inverter output.

 

UPS power supply has gradually become the protector of important equipment. Due to the uncertainty of the status of UPS lithium-ion batteries, system paralysis and loss of important data have resulted in disastrous consequences and huge losses. Therefore, it is very important to use and maintain UPS lithium-ion batteries correctly.

Scrapping the waste export levy could threaten Australia’s emerging lithium battery recycling industry

As electric vehicle (EV) demand accelerates, so does the need for lithium batteries. But these batteries contain valuable critical minerals, as well as toxic materials, so they should not be treated as common waste.

Unlike China and some European countries, Australia lacks a dedicated lithium battery recycling facility. Just 10% of Australia’s lithium battery waste was “recycled” in 2021. This means the batteries were collected and shredded locally before being sent overseas for recycling.

Shipping large volumes of spent batteries overseas is complex and risky. Lithium batteries have been known to start fires. A cargo ship laden with lithium batteries caught fire off the coast of Alaska in December 2023. The fire burned for days.

Similarly, a fire broke out on a cargo ship carrying luxury vehicles (including EVs) near Portugal’s Azores Islands in February 2022. The risk of fire is even greater for spent EV batteries because they are more likely to be damaged or unsafe.

Efforts to recycle batteries onshore have now been jeopardized by the decision—announced last week ahead of this week’s federal budget—to scrap plans for a waste export levy. The proposed A$4 per ton levy on waste exports would have come into effect on July 1.

Scrapping the levy will pave the way for even more waste to be exported rather than recycled here. We believe there should be exceptions for spent lithium batteries—for several reasons. These include safety concerns around shipping and the loss of critical minerals.

By recycling onshore, we can retain these resources, build new industries and develop a circular economy. We should also prepare for the possibility that other countries will at some stage refuse to accept our waste. Then we will be forced to stockpile these batteries, at great risk.

Lithium batteries

Spent EV batteries are accumulating rapidly

EV sales are growing exponentially. Globally, one in five new cars are electric. More than half of all cars sold by 2040 will likely be EVs.

Beneath each sleek exterior is a hefty lithium battery with an average lifespan of just five to eight years.

According to the International Energy Agency, EVs generated about 500,000 tons of battery waste in 2019 alone. This waste is forecast to reach 8 million tons by 2040.

A 2016 report for the federal government forecasts at least 20% annual growth in Australian lithium battery waste to 136,000 tons a year by 2036.

CSIRO explored the potential for lithium battery recycling and reuse in 2021. But little has happened since.

Meanwhile, the mountain of waste continues to grow. It is estimated 360,000 tons of EV batteries will be spent by 2040 and 1.6 million tons by 2050.

Battery recycling is a must, not a choice

Disposal of lithium batteries can cause fires and explosions in waste management facilities and landfills. If a battery is punctured, or short-circuits, the residual electricity can spark fires or explode. The batteries can also leak metals such as cobalt, nickel or manganese, threatening ecosystems and human health.

The battery fluid is harmful to humans as it is linked to various health effects including heart attacks, asthma, cancer, eye damage, reproductive toxicity, skin sensitisation, damage to bones and kidneys and other symptoms.

Lithium battery wastes are overground mines

Rather than being seen as a liability, the growing pile of spent lithium batteries could represent an economic opportunity for Australia. The battery pack in a BMW i3 electric vehicle, for example, contains 6kg of lithium, 35kg of graphite, 2kg of cobalt, 12kg of nickel and 12kg of manganese. These valuable resources will be wasted if the batteries are exported or sent to landfill.

If the raw materials were instead recovered and processed onshore, this could translate into a burgeoning industry worth A$3.1 billion, using Australia’s existing expertise in mining and resource recovery.

new energy battery

It’s time to get serious about battery recycling

The federal government missed an opportunity to include infrastructure for battery recycling in its A$250 million Recycling Modernisation Fund. These funds were limited to waste glass, plastic, tires, paper and cardboard.

This delays the establishment of onshore capacity for battery recycling and makes us reliant on exporting waste batteries overseas.

To boost recycling, we must develop clear regulations and guidelines aligned with global standards, including stringent restrictions on landfill.

In addition, incentives such as tax credits and rebates for battery recycling programs will encourage investment in this area and drive progress. Such measures in Europe make the legislated target for lithium recovery from waste batteries (63% by 2027) possible, cutting reliance on imports of raw materials.

We urgently need to develop a comprehensive waste management strategy dedicated to the responsible collection and recycling of waste batteries. Such a strategy is crucial to safeguard both the environment and communities from the potential hazards associated with improper disposal, promoting resource conservation and creating a circular economy for these critical energy storage devices.

Lithium vs. Ni-MH Batteries: Which is Safer?

NI-MH-Battery-Pack

Compared with lithium batteries(Li-ion), nickel-metal hydride batteries(Ni-MH) are superior in terms of safety.

When evaluating battery safety, nickel-metal hydride (Ni-MH) batteries generally offer a safer profile compared to lithium-ion (Li-ion) batteries. This makes Ni-MH a compelling choice for applications where thermal stability is paramount.

Why Ni-MH Batteries Excel in Safety

Ni-MH batteries possess inherent characteristics that contribute to their superior safety. Their relatively low specific heat capacity and energy density mean they are less prone to rapid temperature increases. Crucially, the high melting point of 400°C for Ni-MH batteries significantly reduces the risk of thermal runaway. Even under extreme stress conditions such as collision, extrusion, puncture, or short circuits, Ni-MH battery packs are less likely to experience a dramatic temperature surge leading to spontaneous combustion. The mature manufacturing processes and stable quality control in Ni-MH battery production further enhance their reliability and safety over time.

Understanding Lithium-Ion Battery Safety Concerns

In contrast, Li-ion battery safety presents more challenges due to the high reactivity of lithium ions and their higher energy density. The flammable nature of Li-ion battery raw materials is a critical factor. Should a Li-ion battery cell experience a short circuit or other damaging events, the internal temperature can rise sharply. This can trigger a violent chemical reaction within the electrolyte, increasing the risk of the battery pack catching fire or even exploding.

Ni-MH-battery-7.2v-3.3ah

After years of technological development, the mature manufacturing process and stable quality of nickel-metal hydride batteries have greatly improved the safety of the batteries.

In comparison, lithium batteries(Li-ion) are not as safe as nickel-metal hydride batteries, mainly because lithium ions(Li-ion) are more active and have higher energy density. At the same time, the raw materials of lithium batteries(Li-ion) are flammable. Once the battery is short-circuited due to various destructive factors and the temperature rises, the internal electrolyte will undergo a violent chemical reaction, which may cause the battery to spontaneously combust.

Investigating the origins of critical deformations in Li-ion batteries

Lithium ion batteries presently are the ubiquitous source of electrical energy in mobile devices, and the key technology for e-mobility and energy storage. Massive interdisciplinary research efforts are underway both to develop practical alternatives that are more sustainable and environmentally friendly, and to develop batteries that are safer, more performing, and longer-lasting—particularly for applications demanding high capacity and very dense energy storage.

Understanding degradations and failure mechanisms in detail opens opportunities to better predict and mitigate them.

In a new study, a team of researchers led by the Institute of Interdisciplinary Research of the CEA, the Institut Laue Langevin (ILL) and the European Synchrotron (ESRF) in collaboration has examined Lithium ion batteries during their lifetime using state-of-the-art, non-intrusive imaging techniques available at neutron and X-ray sources.

The team’s paper is published in the journal Energy & Environmental Science.

Neutrons and photons are largely complementary. Neutrons are particularly good at seeing lithium and other light elements, while X-rays are sensitive to heavy elements, such as nickel and copper. Their sophisticated combination allowed the researchers to gain multidimensional information on the components and elements inside working battery cells.

The team identified macroscopic deformations in the wound structure of the copper current collector. The deformed areas already existed in fresh battery cells that had only gone through the initial activation cycle (the first charging-discharging cycle). Further investigations revealed that these defects were due to local accumulations of silicon occurring during electrode manufacturing. Upon activation, the largest agglomerates expanded heavily, which led to deformations in the current collector, wasting capacity before the cell ever went into use.

 

sodium ion battery

It was possible to determine how large these accumulations must be to become a problem: cell structure and functioning is compromised for silicon agglomerations with a size above 50 microns. This is crucial information for both quality control and future developments. Erik Lübke, Ph.D. student at ILL and the main author of the study, summarizes, “In fact, resources are wasted when this happens, and we have quantified the effects and understood their causes.”

Full-field, high-resolution 3D transmission tomography enabled the inspection of the entire volume of the battery cell, revealing the presence of a number of defect features. These were more closely investigated at selected cross-sectional 2D slices.

The neutron tomography scans (with simultaneous low intensity X-ray computed tomography scans) were carried out at the NeXT instrument of the ILL. Synchrotron X-ray tomography scans of the very same cells were then measured at the ESRF using two beamlines, BM05 and the high-energy ID31 beamline for phase-contrast and scattering tomography respectively.

At NeXT, 3D high resolution neutron tomography is coupled with X-ray tomography to image the entire cell. Erik Lübke explains, “X-rays give the basic structure, making it possible to know exactly where we are when we use neutrons to examine the spatial distribution of lithium in detail,” benefiting from “the best neutron resolution you can get anywhere in the world.”

Selected parts of the cell were then examined in further detail using several different X-ray tomography techniques at the ESRF high-energy beamlines. Acquiring data during the battery charging process (a so-called operando experiment) made it possible to gather more information about the reaction dynamics in the defective regions: Lithium diffusion is partly blocked there, and even when most of the cell is fully charged these areas remain without lithium in their center.

To ensure the industrial relevance of the results, the team tested cylindrical silicon-based lithium ion battery cells manufactured according to industry standards. Cells of this format are in commercial use in small electronic devices such as medical sensors, headphones, and smart devices. However, the size was reduced for a better compatibility with the experimental requirements. Both fresh cells and aged ones (cycled over 700 times with roughly 50% remaining capacity) were imaged, in charged and discharged states. The different techniques were applied to the very same cells.

Ventilation Needs of LiFePO4 Batteries

Unlike traditional lead-acid batteries, which release hydrogen gas during charging and require significant ventilation to prevent gas accumulation, LiFePO4 battery pack are fundamentally different:

  • Gas Emission: LiFePO4 batteries do not produce dangerous gases under normal operating conditions, thanks to their stable chemistry and the quality of the manufacturing process.
  • Thermal Regulation: While LiFePO4 batteries generate less heat during operation and charging, they do not typically require active ventilation systems. However, it is essential to ensure that they are not exposed to high ambient temperatures or direct sunlight for prolonged periods.

Installation Considerations

While LiFePO4 batteries do not require traditional venting systems, proper installation is crucial to maximize their performance and lifespan:

  • Temperature Management: Ensure that LiFePO4 batteries are installed in a space with ambient temperature control to prevent overheating and ensure optimal performance.
  • Physical Placement: Avoid placing batteries in tightly sealed enclosures; allowing for some air circulation will help dissipate any heat generated during high loads or charging.
  • Accessibility: Install the batteries in locations where they can be easily monitored and accessed for maintenance or inspection if necessary.

Advantages of Using LiFePO4 Batteries

Choosing LiFePO4 batteries offers several advantages over traditional battery technologies:

  • Maintenance-Free: These batteries require minimal maintenance, eliminating the need for regular water top-ups and acid spill cleanup.
  • Eco-Friendly: With no harmful emissions and a lower environmental impact than lead-acid batteries, LiFePO4 batteries are an eco-friendlier choice.
