New process makes battery production more eco-friendly

Switching from gas-powered cars to electric vehicles is one way to reduce carbon emissions, but building the lithium-ion battery that power those EVs can be an energy-intensive and polluting process itself. Now researchers at Dalhousie University have developed a manufacturing process that is cheaper and greener.

“Making lithium-ion battery cathode material takes a lot of energy and water, and produces waste. It has the biggest impact on the environment, especially the CO2 footprint of the battery,” says Dr. Mark Obrovac, a professor in Dalhousie University’s Departments of Chemistry and Physics & Atmospheric Science.

li-ion-battery

“We wanted to see if there were more environmentally friendly and sustainable—and less expensive—ways to make these materials.”

Most electric vehicle batteries use lithium nickel manganese cobalt oxide (NMC), with the elements mixed in the crystal structure of the cathode. They are typically made by dissolving the elements in water then using the crystals that form when the elements come together as a solid.

That process takes a lot of water—which then has to be treated to clean it—and energy, which is the main source of the cost and carbon footprint of the batteries. Using the Canadian Light Source (CLS) at the University of Saskatchewan, Obrovac and his team investigated whether they could use an all-dry process to get the same results while saving energy, water, and money.

Their work has been published in two papers, in ACS Omega and the Journal of the Electrochemical Society.

“We wanted to see, can you get the same quality if you take dry materials and combine them using simple processes that you’d find in any large-scale factory and heat them up,” he says. “And under what conditions can you do that to get commercial-grade material while cutting out the water and the waste?”

Cathodes made from dry materials are sometimes not as homogeneous as those made in water, so the team tried a variety of methods using different oxides and heating regimes under different temperatures and pressures to determine what worked best.

They used the Brockhouse beamline at CLS to peer inside the furnace as they tried these different experiments, to see exactly what was happening during the process. “What we found was important information about how we can improve the process so that what comes out is a higher-grade NMC-type cathode material,” says Obrovac.

The highest quality cathodes available now are made from single crystals with particles about 5 microns in diameter. By carefully adjusting their starting materials and furnace conditions, Obrovac’s team was able to reproduce those qualities using an all-dry process, making cathode materials comparable to the best ones on the market today.

Obrovac has partnered with the Nova Scotia-based battery company NOVONIX, which is using all-dry processes to produce cathode materials at the company’s pilot-scale facility in Dartmouth. That facility is capable of producing 10 tonnes per annum of cathode material, with methods that offer an estimated 30% lower capital costs than the conventional (wet) methods, 50% lower operating costs, and uses 25% less energy, while requiring no process water, and generating zero waste.

“These are big numbers, it’s very much a step-change in the production of these battery materials,” says Obrovac. “It should result in lower-cost batteries overall with a substantially lower global warming footprint.”

New strategy improves performance of spent high-voltage lithium cobalt oxide batteries

In a study published in Advanced Materials, a research team led by Prof. Zhang Yunxia from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has developed an integrated bulk and surface commodification strategy to upgrade spent lithium cobalt oxide (S-LCO) batteries to operate at high voltages.

As the demand for high energy density storage devices grows, there’s a need to find sustainable ways to upgrade old LiCoO2 (LCO) batteries into more stable, high-voltage cathode materials.

In this study, the researchers developed a simple and effective method for upgrading LCO batteries. They used a combination of wet chemical treatment, heating, and a special phosphorus coating technique.

This process involved adding extra lithium, applying a uniform coating of lithium phosphate/cobalt phosphide (LPO/CP) to the surface, and incorporating manganese into the bulk material, along with a gradient of phosphorus near the surface. These modifications were all achieved simultaneously, resulting in significantly improved battery performance.

The result of these modifications is an improved LCO cathode, named MP-LCO@LPO/CP, which shows significantly improved electrochemical performance. The improved cathode exhibits high specific capacity and excellent cycling stability.

The researchers also investigated why the upgraded cathode performs so well at high voltages. They found that the modifications improve both structural stability and electrochemical properties, resulting in improved battery performance.

“This method is simple and easy to scale up, so it could also be used to recycle other waste cathode materials. This approach has great potential for the sustainable development of the lithium-ion battery industry,” said Prof. Zhang.

Do li ion batteries have memory

lithium ion battery pack

Understanding the Memory Effect in Batteries

Origins and Impact of the Memory Effect

The memory effect originally described a condition observed primarily in Nickel-Cadmium (NiCd) batteries, where they appeared to “forget” their full charge capacity if they were repeatedly recharged after being only partially discharged. This effect causes the battery to lose track of its full energy capacity, which could be misleading as to how much energy the battery could hold and deliver.
  1. Mechanism Behind Memory Effect:
    1. Formation of Memory: In NiCd batteries, if they are not fully discharged before charging, the areas of the battery that remain inactive start to form crystals. These crystals reduce the active material available for future discharges and charge cycles, effectively decreasing the usable capacity of the battery.
    2. Impact on Device Operation: For devices relying on these batteries, this could translate to shorter operational times after each charge, as the battery “thinks” it’s empty when there’s still unused energy left. This could lead to more frequent charging cycles, which in turn accelerates the wear and tear on the battery.
  2. Historical Context and Advances:
    1. Early Observations and Solutions: When the memory effect was first identified, it led to recommendations that users fully discharge their NiCd batteries before recharging them to “reset” the memory. This was a cumbersome process and not always practical for all types of devices, especially emergency equipment that needed constant, reliable power.
    2. Technological Responses: The inconvenience and operational inefficiency led to significant research into alternative battery chemistries that would not exhibit this problematic behavior, setting the stage for the development of lithium-ion batteries.

nicd-memory-effect

Characteristics of Lithium-Ion Batteries Against Memory Effect

Lithium-ion batteries(LI-ION BATTERY) were developed in part to address the limitations seen in earlier battery technologies, including the memory effect. Their chemistry and operational dynamics differ significantly from those of NiCd batteries, giving them a natural resistance to memory issues.
  1. Chemical Properties and Charge Management:
    1. No Memory Formation: Unlike NiCd batteries, lithium-ion batteries use a chemistry that does not lead to the crystallization of inactive areas during partial discharges. This is due to the movement of lithium ions in a liquid electrolyte between the anode and cathode, a process that doesn’t degrade the electrodes in a way that would create a memory.
    2. Efficient Charge Cycles: Lithium-ion batteries can handle partial discharge and recharge cycles without any significant loss in capacity. This flexibility makes them ideal for modern electronics that require frequent and varied usage patterns.
  2. Longevity and Performance:
    1. Cycle Life: Lithium-ion batteries typically have a cycle life of several hundred to several thousand cycles, with a gradual decrease in capacity. This degradation is uniform and predictable, unlike the abrupt and irregular capacity loss caused by the memory effect in NiCd batteries.
    2. Adaptability in Usage: The robustness of lithium-ion batteries in various discharge states makes them suitable for a wide range of applications, from mobile phones that are often charged overnight regardless of their remaining battery level, to electric vehicles that benefit from “top-up” charges without needing a full depletion of battery life.

FAA and IATA Guidelines on Lithium-Ion Batteries

The Federal Aviation Administration (FAA) in the United States and the International Air Transport Association (IATA) provide specific guidelines on how lithium-ion batteries should be carried on aircraft:
  1. Carry-On vs. Checked Baggage:
    1. Carry-On Luggage: Passengers are encouraged to carry lithium-ion batteries in their carry-on baggage. This allows any issues, such as a short circuit or smoke, to be addressed quickly by the crew.
    2. Checked Baggage: With few exceptions (like medical devices), lithium-ion batteries should not be placed in checked baggage to prevent any risk where it cannot be immediately managed.
  2. Battery Capacity Restrictions:
    1. Watt-Hour Rating: The allowable size for lithium-ion batteries in carry-on luggage is generally restricted to batteries with a Watt-hour (Wh) rating of not more than 100 Wh. Batteries with a rating between 100 Wh and 160 Wh can be carried with airline approval, usually limited to two spare batteries per passenger.
    2. Special Permissions: Batteries above 160 Wh are typically banned from being brought onto planes as carry-on or checked baggage unless they are installed in a device.

Safety Concerns with Lithium-Ion Batteries on Planes

The primary reason for these stringent regulations is the risk of thermal runaway, a process where excessive heat leads to a rapid increase in temperature and pressure in the battery. This can cause:
  1. Fire: If a lithium-ion battery overheats, it can catch fire. In an enclosed space like an aircraft, this can be particularly dangerous.
  2. Explosions: In extreme cases, the build-up of pressure and heat can lead to explosions, which might cause significant harm in the cabin or even jeopardize the aircraft’s safety.
