Solid State Battery: Could expensive EV batteries be coming to an end? Scientists have developed a super sodium battery; learn its features...

Electric vehicles are rapidly gaining popularity in India. Simultaneously, the cost of batteries is also increasing. In today's world, where everything from mobile phones and laptops to EVs relies on batteries, the shortcomings of lithium-ion batteries are becoming apparent.

Dr. Ganga Jha, a scientist at the Department of Mechanical and Materials Engineering at Western University in Canada, is working on this. They claim that sodium is abundant on Earth and is many times cheaper than lithium.

Nearly Zero Risk of Fire
Solid-state batteries use a solid electrolyte instead of a liquid, reducing the risk of fire to almost zero. This increases energy density, meaning the battery lasts longer. High temperature stability, long life, and increased charge cycles are among the advantages.

The biggest challenge was how to ensure sodium ions move quickly in the solid electrolyte. Dr. Jha's team solved this challenge by explaining that a new sulfur- and chlorine-based solid material makes the sulfur structure flexible, increasing the speed of sodium ions many times. It remains stable even under conditions such as temperature and vibration. It does not deteriorate even when in contact with other battery parts. This characteristic makes it a next-generation battery.

In-depth investigation using X-ray technology
Using the high-energy X-ray system at Canada's CLS (Canadian Light Source), scientists precisely examined ion movement and chemical bonds. This investigation shows that this new material is ideally suited for industrial battery manufacturing.

If industrial production begins, it will significantly transform the EV and energy storage sectors. EV prices will decrease, battery safety will increase, dependence on lithium will decrease, and the path to large-scale, affordable energy storage will open up. This technology could usher in a new era of energy storage.
