Three years ago, sodium ion batteries emerged as a replacement to solve the problem of soaring raw material prices and production shortages for lithium batteries. And then gradually disappeared.

In 2022, against the background of soaring prices of lithium battery raw materials, the concept of sodium-ion batteries suddenly exploded. Major battery manufacturers have successively launched this kind of battery products.

However, in the past two years, the lithium battery industry chain has expanded production on a large scale, and the price of lithium batteries has dropped. The low-cost advantage of sodium-ion batteries has weakened, the technology is immature, and its performance is not as good as that of lithium batteries. Subject to energy density and cycle times, sodium-ion batteries are generally used in mini-cars and small cars.

However, sodium-ion batteries have a certain space for survival in the energy storage market. Because they can just meet the needs of energy storage batteries for low investment prices, safer safety, and long life. They may be deployed on a large scale in the future.

At present, many battery companies have abandoned their already developed electric vehicle product lines and switched to energy storage product lines. According to industry estimates, more than half of sodium battery companies have added new energy storage product lines. In addition, the academic community has also been insisting on the research and development of sodium batteries. It is expected to make a breakthrough in the energy storage market.

What determines the cycle life of batteries? And, more importantly, how can we extend it? An international research team led by TU Delft has discovered that local disorder in the oxide cathode material increases the number of times  lithium ion battery can be charged and discharged. Their results have been published in Nature.

Rechargeable batteries are a key ingredient of the energy transition, especially now that more and more renewable energy is becoming available. Among the many types of rechargeable batteries, Lithium ion battery pack are among the most powerful and widely used ones.

To electrically connect them, layered oxides are often used as electrodes. However, their atomic structure becomes unstable when the battery is being charged. This ultimately affects the battery cycle life.

To solve this problem, the “Storage of Electrochemical Energy” group at TU Delft teamed up with international researchers. Qidi Wang, the paper’s lead author says, “The layered oxide used as cathode material for Li-ion batteries is neatly ordered. We conducted a structure design study to introduce chemical short-range disorder into this material through an improved synthesis method. As a result, it became more stable during battery use.”

The improved structural stability almost doubled the battery’s capacity retention after 200 charging/discharging cycles. In addition, this chemical short-range disorder increases the charge transfer in the electrode, resulting in shorter charging times. The team demonstrated these advantages for well-established commercial cathodes such as lithium cobalt oxide (LiCoO2) and lithium nickel manganese cobalt oxide (NMC811).

The outcomes could lead to a new generation of Li-ion batteries, with a lower manufacturing cost and smaller CO2 footprint per unit of energy stored over its lifetime. The team will next investigate if the same material design principles can be used to build cathodes from raw materials that are less scarce.

“Both cobalt and nickel are so-called critical materials for energy technologies and it would be a good thing to reduce the use these materials in batteries,” says the paper’s senior author, Marnix Wagemaker.

The difference between Li-PO battery and metal casing lithium battery mainly refers to the material of the shell.

Polymer batteries are just liquid lithium-ion batteries with a polymer shell. Structurally, it is packaged with aluminum-plastic film. If a safety hazard occurs, the aluminum-plastic film of the battery will only inflate and crack at most.

The metal casing lithium-ion battery is made of steel or aluminum, and the cover assembly has an explosion-proof power-off function.

Compared with metal casing lithium ion batteries, polymer batteries have more or less advantages in terms of weight, capacity, shape, etc.

However, polymer batteries generally have smaller capacities and higher molding costs. The MOQ is high for customized battery, so the current market share of soft-pack lithium-ion batteries is relatively small.

LiTypes of Lithium-ion

Charge-recharge cycling of lithium-super-rich iron oxide, a cost-effective and high-capacity cathode for new-generation lithium-ion batteries, can be greatly improved by doping with readily available mineral elements.

The energy capacity and charge-recharge cycling (cyclability) of lithium-iron-oxide, a cost-effective cathode material for rechargeable lithium-ion batteries, is improved by adding small amounts of abundant elements. The development, achieved by researchers at Hokkaido University, Tohoku University, and Nagoya Institute of Technology, is reported in the journal ACS Materials Letters.

Lithium ion batteries have become indispensable in modern life, used in a multitude of applications including mobile phones, electric vehicles, and large power storage systems.

A constant research effort is underway to increase their capacity, efficiency, and sustainability. A major challenge is to reduce the reliance on rare and expensive resources. One approach is to use more efficient and sustainable materials for the battery cathodes, where key electron exchange processes occur.

The researchers worked to improve the performance of cathodes based on a particular lithium-iron-oxide compound. In 2023, they reported a promising cathode material, Li5FeO4, that exhibits a high capacity using iron and oxygen redox reactions. However, its development encountered problems associated with the production of oxygen during charging-recharging cycling.

“We have now found that the cyclability could be significantly enhanced by doping small amounts of abundantly available elements such as aluminum, silicon, phosphorus, and sulfur into the cathode’s crystal structure,” says Associate Professor Hiroaki Kobayashi at the Department of Chemistry, Faculty of Science, Hokkaido University.

18500 3.7v 1100mah Lithium battery

A crucial chemical aspect of the enhancement proved to be the formation of strong ‘covalent’ bonds between the dopant and oxygen atoms within the structure. These bonds hold atoms together when electrons are shared between the atoms, rather than the ‘ionic’ interaction between positive and negatively charged ions.

“The covalent bonding between the dopant and oxygen atoms makes the problematic release of oxygen less energetically favorable, and therefore less likely to occur,” says Kobayashi.

The researchers used X-ray absorption analysis and theoretical calculations to explore the fine details of changes in the structure of the cathode material caused by introducing different dopant elements. This allowed them to propose theoretical explanations for the improvements they observed. They also used electrochemical analysis to quantify the improvements in the cathode’s energy capacity, stability and the cycling between charging and discharging phases, showing an increase in capacity retention from 50% to 90%.

“We will continue to develop these new insights, hoping to make a significant contribution to the advances in battery technology that will be crucial if electric power is to widely replace fossil fuel use, as required by global efforts to combat climate change,” Kobayashi concludes.

The next phase of the research will include exploring the challenges and possibilities in scaling up the methods into technology ready for commercialization.

A green industrial future for Europe may depend on an element that is part of a household staple: table salt. Dr. John Abou-Rjeily, a researcher at Tiamat Energy in France, is using sodium to develop rechargeable batteries. Sodium is a part of sodium chloride, an ionic compound that is the technical name for ordinary salt.

 

The idea behind sodium-ion batteries is to reduce Europe’s reliance on the lithium-ion ones that power everything from toothbrushes and mobile phones to mopeds and cars.

Today’s batteries include materials such as lithium, nickel and cobalt that are both scarce and toxic, whereas sodium is one of the most plentiful elements on Earth.

“Sodium-ion batteries are based on more abundant and safer materials than lithium-ion batteries,” said Abou-Rjeily. “There’s not enough lithium ions and cobalt and nickel to meet everyone’s needs.”

He is a research and development engineer at Tiamat, which designs and manufactures sodium-ion batteries.

Abou-Rjeily led a research project to develop sodium-ion batteries that have commercial appeal and can serve as a new foundation for European manufacturing.

Called NAIMA, the project ran from December 2019 through May 2023. It featured companies, research institutions and universities in Bulgaria, Belgium, France, Germany, the Netherlands, Slovenia, Spain and Sweden.

Battery charge

Batteries are central to Europe’s drive to replace fossil fuels with renewable-energy sources such as wind and solar power. More clean energy in Europe requires new storage capacity that batteries can provide.

The European battery market could be worth as much as €250 billion a year as of 2025. Europe aims to increase its share of global battery-cell production to as high as 25% this decade from 3% in 2018, chipping away at Asia’s 85% dominance.

The research covers all segments of the supply chain—from access to raw materials needed to make batteries and the infrastructure required for storing energy to “smart grids” that automatically charge vehicles when power is cheapest and battery designs that ensure recycling.

Lithium-ion batteries can store lots of energy in a small space, making them winners for smart phones and electric cars. Sodium-ion batteries are slightly bigger and potentially cheaper, making them candidates for storing energy in places such as homes, power tools and small vehicles.

French connection

Abou-Rjeily, a trained chemist from Lebanon, moved to France in 2016 to pursue an interest in environmental sustainability.

He is at home with Tiamat, whose sodium-ion batteries exclude lithium, cobalt and copper and largely avoid nickel too. The company is a spinoff from the French National Center for Scientific Research, or CNRS, which was among the NAIMA participants.

Lithium, cobalt, copper and nickel are on an EU list of critical raw materials, highlighting concerns in Europe about reliance on foreign suppliers and supply squeezes.

For example, when it comes to lithium-ion batteries worldwide, China manufactured almost 80% of them in 2021.

Furthermore, most global production of lithium-ion batteries is expected to go to the automotive industry.

Tiamat plans in 2026 to open a gigafactory in the French city of Amiens to produce sodium-ion batteries suitable initially for equipment such as power tools, according to Abou-Rjeily.

He said NAIMA helped advance the company’s battery know-how.

The project also helped partners move forward with a type of sodium-ion battery for renewable-energy storage. This kind of battery could also one day be suitable for some cars.

While it wouldn’t ever challenge the 500-kilometer capacity of lithium-ion batteries, this sodium-ion type could be more competitive for smaller stretches, according to Abou-Rjeily.

“They could be cheaper for short and medium driving distances,” he said.

Home base

An energy link between cars and homes through sodium-ion batteries is a vision of Dr. Magdalena Graczyk-Zajac, a visiting professor at the Technical University Darmstadt in Germany.

Also an electrochemist at the German energy company EnBW, she is involved in a project to develop a sodium-ion battery for homes. Called SIMBA, the project is due to wrap up in June 2024 after three and a half years.

Graczyk-Zajac paints a future where energy captured by photovoltaic panels on homes is stored in a rechargeable household sodium-ion battery. The battery would then power the homes and charge the inhabitants’ electric vehicles.

Graczyk-Zajac said such a scenario would mean a big cut in transportation costs.

“You could be driving your car for free for eight to nine months of the year,” she said.

Household gains

While sodium-ion and lithium batteries work in a similar way, sodium is a larger ion than lithium. That’s one reason that a sodium-ion battery takes up a little more space.

For home storage, such a battery would be placed underground or in a garage, so a slightly larger battery wouldn’t matter much, according to Graczyk-Zajac.

SIMBA, which involves almost 20 research institutes, universities and companies from across Europe, has put together some essential components of a home sodium-ion battery for laboratory testing.

One part, the anode, is made from hard carbon, which can be manufactured from wood or biowaste. Another—the cathode—can be made of a material called Prussian white.

While lithium-ion cathodes frequently contain cobalt, this Prussian white cathode contains iron, which is a more abundant and cheaper metal.

This cathode was developed by Altris, a spinoff in 2017 from Uppsala University in Sweden—one of the SIMBA participants.

Altris made headlines in November 2023 when its industry partner, Sweden-based Northvolt, announced that it would make batteries in Europe with the cathode.

In general, sodium-ion batteries promise households in Europe the chance for cheaper and cleaner energy.

The batteries also offer the prospect of financial gains through the storage and then either sale of spare electricity to the grid when home production is higher than needed or later use in the home.

Graczyk-Zajac recommends the later-use option. “A householder would save more money by just keeping that energy,” she said.

lifepo4 battery 12V

In the landscape of modern battery technologies, LiFePO4 (lithium iron phosphate) batteries have emerged as a standout choice due to their reputed safety and reliability. Especially prevalent in applications where safety cannot be compromised, such as electric vehicles and renewable energy systems, LiFePO4 batteries offer an appealing alternative to traditional lithium-ion batteries. This article delves deeply into the safety features of LiFePO4 batteries, compares them with other battery types, and discusses how Himax Electronics utilizes this technology to deliver superior safety in battery solutions.

lifepo4 battery 12V

Understanding LiFePO4 Battery Safety

Chemical and Thermal Stability:
LiFePO4 batteries are constructed using lithium iron phosphate as the cathode material, which inherently provides significant safety advantages. The phosphate chemistry grants these batteries a strong bond that withstands extreme abuse conditions better than other lithium chemistries. This chemical stability leads to superior thermal stability, meaning LiFePO4 batteries are less likely to suffer from thermal runaway—a condition where increased temperature causes a reaction that continuously increases temperature, leading to fires or explosions.

Overcharge and Overdischarge Resistance:
One of the significant risks with battery technologies is the potential for overcharging or deep discharging, which can compromise battery integrity and safety. LiFePO4 batteries inherently resist both conditions. They maintain a stable voltage range during charging and discharging, which helps prevent the scenarios where voltage spikes or dips could lead to hazardous situations.

Comparative Safety with Other Battery Technologies

LiFePO4 vs. Lithium-Cobalt Oxide (LiCoO2):
While LiCoO2 batteries, commonly used in mobile devices and laptops, store higher amounts of energy, they pose higher risks of thermal runaway and are more sensitive to high temperatures. In contrast, LiFePO4 batteries operate safely at higher temperatures and are significantly less prone to catastrophic failure when damaged.

LiFePO4 vs. Nickel-Metal Hydride (NiMH):
NiMH batteries, found in many hybrid vehicles, are less volatile than traditional lithium-ion batteries but still lag behind LiFePO4 in terms of overall safety, lifespan, and weight efficiency. LiFePO4 batteries offer a lighter, more efficient solution with a considerably longer life cycle and better stability during thermal stress.
