Nissan Develops New Battery Technology

Nissan and Nissan Arc, Ltd. have teamed up to push for further developments in the auto industry. With the popularity of electric cars, Nissan has been finding new ways to improve innovation.

Together, they found a way to improve the performance of lithium-ion batteries. How? The simple answer is silicon.

Current lithium-ion batteries use graphite, but Nissan’s recent finding suggest that silicon holds more lithium than graphite. When it’s charged, graphite materials expand. But silicon materials expand even more. This discovery means that if silicon is used, batteries can store more lithium-ions than they currently do, which would improve the battery’s range.

“The utilization of this analysis method in our future R&D will surely contribute to extending the cruising range of future zero-emission vehicles,” said Takao Asami, senior vice president of Nissan Motor Co., Ltd. and President of Nissan Arc Ltd.

The reason it hasn’t been used so far is because the silicon’s base structure was unknown. But with Nissan’s new studies, they’re able to better understand silicon’s structure, which makes it easier to develop it and utilize it in new batteries.

Hopefully, we’ll be seeing these developments for ourselves soon!
