When it comes to building hybrid and electric vehicles, a lot of the development goes into the batteries.

These battery packs (typically lithium-ion) often cost a lot to produce, which is what drives the prices of hybrids and EVs up. The technology in the batteries also play the biggest role in determining driving range. Nissan, however, wants to change that. As a result, the automaker is currently developing safer, and cheaper lithium-ion batteries that also have increased charging capacity.

“We believe the widespread adoption of this technology will contribute to fulfilling the UN’s sustainable development goals and help realize a sustainable, low-carbon society,” said Hideki Kimata, vice president of the corporate strategy and business development division at Nissan.

Nissan, together with APB Corporation, will be producing what is called all-polymer batteries. According to the company, it is the next generation of lithium-ion batteries. The all-polymer battery with a bipolar structure works by using polymers and metal electrodes used in conventional batteries. As a result, the charging capacity is increased and also makes the battery safer by replacing liquid electrolytes with the aforementioned polymers. The more simplified structure also lowers overall cost. You can see how it works compared to a conventional lithium-ion battery in detail by checking the illustration above.

There is no word as to when the new all-polymer batteries will be fitted into their production hybrid and electric vehicles. However, Nissan did say that the application can also be used for stationary batteries for solar systems or electricity purchased from the grid during off-peak hours.
