Tesla long promised big moves for its future batteries, and Panasonic hopes its new prototype battery will deliver for the electric carmaker. On Monday, Automotive News reported on the Japanese company’s new prototype battery complete specifically for Tesla. It promises fives times more energy storage, which may increase ranges significantly.

In addition to more energy, the battery will cost 50% less to produce and help boost battery issues at Panasonic “100-fold,” by 2030, according to the record. These three elements could produce a game-changing battery pack for Tesla with a touch cost and more range at the core of EV adoption hurdles. Panasonic did not immediately return a request for comment and more examine on the prototype battery. Tesla does not operate a Pro-reDemocrat relations department to field requests for comment.

However, according to Automotive News, the move to interpretation the prototype battery and making it a reality comes down to strengthening its ties with the EV maker. While Tesla has a long relationship with Panasonic, it’s also begun forging supplier requisitions with South Korea’s LG Energy Solutions and China’s CATL to acquire lithium-iron-phosphate (LFP) batteries for its Standard Range models. Panasonic has no plans to acquire LFP units, a technology Tesla plans to embrace to acquire cheaper batteries for these cars. They’re also kinder to the environment when it comes to sourcing fewer rare humankind materials.
