Current development status of sodium batteries

Himax - decorating image

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.

Using sodium to develop rechargeable batteries may bolster the EU’s green ambitions

portable device decorate img

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.

https://youtu.be/ojLGPk4UltE

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.

Fire-resistant sodium battery balances safety, cost and performance

portable device decorate img

A sodium battery developed by researchers at The University of Texas at Austin significantly reduces fire risks from the technology, while also relying on inexpensive, abundant materials to serve as its building blocks.

Though battery fires are rare, increased battery usage means these incidents are on the rise.

The secret ingredient to this sodium battery breakthrough, published recently in Nature Energy, is a solid diluent. The researchers used a salt-based solid diluent in the electrolyte, facilitating the charge-discharge cycle. A specific type of salt—sodium nitrate—allowed the researchers to deploy just a single, nonflammable solvent in the electrolyte, stabilizing the battery as a whole.

Over time, the multiple liquid solvents in an electrolyte—the component that transfers charge-carrying ions between the battery’s two electrodes—react with other components in ways that degrade batteries and lead to safety risks. Sodium, an alternative to lithium that is one of the key ingredients in this battery, is highly reactive, posing a significant challenge to the adoption of these types of batteries. These reactions can lead to the growth of needle-like filaments called dendrites that can cause the battery to electrically short and even catch fire or explode.

“Batteries catch fire because the liquid solvents in the electrolyte don’t get along with other parts of the battery,” said Arumugam Manthiram, a professor in the Cockrell School of Engineering’s Walker Department of Mechanical Engineering and the lead researcher on the project. “We have reduced that risk from the equation to create a safer, more stable battery.”

In addition to the safety improvement, this new, sodium-based battery represents a less expensive alternative to the lithium-ion batteries that power smartphones, laptops, electric cars and more.

Future Batteries（Article illustrations）-sodium battery

The battery also boasts strong performance. How long a battery lasts on a single charge tends to decline over time. The new sodium battery retained 80% of its capacity over 500 cycles, matching the standard of lithium-ion batteries in smartphones.

“Here we show a sodium battery that is safe and inexpensive to produce, without losing out on performance,” Manthiram said. “It is critical to develop alternatives to lithium-ion batteries that are not just on par with them, but better.”

Though the researchers applied this technique to a sodium battery, they said it could also translate to lithium-ion-based cells, albeit with different materials.

Lithium mining is expensive and has been criticized for its environmental impacts, including heavy groundwater use, soil and water pollution and carbon emissions. By comparison, sodium is available in the ocean, is cheaper and is more environmentally friendly.

Lithium-ion batteries typically also use cobalt, which is expensive and mined mostly in Africa’s Democratic Republic of the Congo, where it has significant impacts on human health and the environment. In 2020, Manthiram demonstrated a novel, cobalt-free lithium-ion battery.

Sodium-ion batteries: How doping works

Compared to lithium batterie, Sodium-ion batteries still have a number of weaknesses that could be remedied by optimizing the battery materials. One possibility is to dope the cathode material with foreign elements. A team from HZB and Humboldt-Universität zu Berlin has now investigated the effects of doping with scandium and magnesium.

The scientists collected data at the X-ray sources BESSY II, PETRA III, and SOLARIS to get a complete picture and uncovered two competing mechanisms that determine the stability of the cathodes. Their research is published in the journal Advanced Materials.

Lithium batterie have the highest possible energy density per kilogram, but lithium batterie resources are limited. Sodium, on the other hand, has a virtually unlimited supply and is the second-best option in terms of energy density. Sodium-ion batteries (SIBs) would therefore be a good alternative, especially if the weight of the batteries is not a major concern, for example in stationary energy storage systems.

However, experts are convinced that the capacity of these batteries could be significantly increased by a targeted material design of the cathodes. Cathode materials made of layered transition metal oxides with the elements nickel and manganese (NMO cathodes) are particularly promising.

They form host structures in which the sodium ions are stored during discharge and released again during charging. However, there is a risk of chemical reactions which may initially improve the capacity, but ultimately degrade the cathode material through local structural changes. This has the consequence of reducing the lifetime of the sodium-ion batteries.

“But we need high capacity with high stability,” says Dr. Katherine Mazzio, who is a member of the joint research group Operando Battery Analysis at HZB and the Humboldt-Universität zu Berlin, headed by Prof Philipp Adelhelm. Spearheaded by Ph.D. student Yongchun Li, they have now investigated how doping with foreign elements affects the NMO cathodes.

Different elements were selected as dopants that have similar ionic radii to nickel (Ni 2+), but different valence states: magnesium (Mg 2+) ions or scandium ions (Sc 3+).

Three years of experiments at BESSY II, PETRA III, and SOLARIS

To decipher the influence of the two elements, they had to carry out experiments at three different X-ray sources.

At BESSY II, they analyzed the samples using resonant inelastic X-ray scattering (RIXS) and X-ray absorption spectroscopy (XAS) in the soft and hard X-ray ranges; at PETRA III, they evaluated structural changes with X-ray diffraction (XRD) and pair distribution function analysis (PDF) with hard X-rays, and for more detailed insights on the element magnesium, they carried out additional soft XAS investigations at the PIRX beamline at SOLARIS.

“The results surprised us,” explains Mazzio. Although doping with scandium leads to fewer structural changes during the electrochemical cycle than doping with magnesium, it does not improve stability. “Until now, it was thought that suppressing phase transitions (and thus volume changes) would also improve the cathode material cycling performance over many cycles. But that’s not enough.”

Magnesium doping suppresses the oxygen redox reaction in NMO even more. This was also unexpected, as magnesium is known to trigger an oxygen redox reaction in layered manganese oxides. “We analyzed different Mg/Ni ratios in NMO and found that the oxygen redox reaction reaches a minimum at a ratio close to 1,” explains Mazzio.

“Only through a combination of advanced X-ray techniques could we show that it is more than just suppression phase transitions that are important for improving the long-term cycling behavior, but also the interplay between Ni and O redox activity dictate performance.”

Engineers develop promising calcium-based battery that’s rechargeable and operates at room temperature

Himax - decorating image

A multi-institutional team of Chinese engineers has developed a proof-of-concept calcium-based battery that withstands 700 charge cycles at room temperature. In their paper published in the journal Nature, the group describes the challenges they addressed in developing the battery and what they have learned about the possible use of calcium-based batteries in consumer products in the future.

The current standard for rechargeable custom lithium battery pack used in consumer products is lithium. But because it is a rare material and has issues such as poor aging and the need to prevent overcharge, scientists have been looking for a suitable replacement. One such material is calcium, which is 2,500 times as abundant as lithium.

Prior research has suggested rechargeable batteries based on calcium should be possible if problems can be resolved. One of the biggest challenges is finding suitable electrolyte and electrode materials that can provide stability and safety.

 

In this new effort, the researchers attempted to develop a useable, rechargeable, calcium–oxygen-based battery—prior research has suggested such pairings are likely to have the highest energy density of calcium-based batteries. Prior efforts to create batteries using this approach have run into problems with inactive discharge materials, and it has also been challenging to find electrolytes that can work with both calcium and oxygen.

To overcome these problems, the team in China created a new type of liquid electrolyte that works with both calcium and oxygen. This involved the use of a two-electron redox process and specific proportions of materials. The result was a battery that could be charged and recharged up to 700 times at room temperature.

The research team also incorporated their battery into flexible fibers which they wove into a textile, presenting the possibility of wearable consumer products. They acknowledge that the battery is still not efficient enough for use in commercial products, but they plan to continue their work to see if it can be improved.
