While it is unclear which firm will win the race to place solid-state batteries in a manufacturing automotive, Toyota and analysis associate Panasonic at the moment have the lead in patents associated to the know-how, Nikkei Asia reported Thursday.
Along with Tokyo-based analysis agency Patent Consult, Nikkei studied patent functions for solid-state battery tech in ten nations and territories filed from 2000 by means of the tip of March of this 12 months.
Toyota was the clear chief with 1,331 recognized patents, adopted by Panasonic with 445 patents. In comparability, the third-place firm—Idemitsu Kosan—holds 272 patents, in line with the report.

It’s value noting that patents are a great way to guage analysis and improvement exercise, however they’re no sturdy indication of how far alongside an organization really is in bringing a specific know-how to manufacturing. Many different automakers and battery suppliers are additionally investing in solid-state battery analysis, lured by claims of higher power density.
Toyota started researching solid-state batteries within the Nineties, in line with Nikkei. It partnered with Panasonic for joint improvement of the tech in 2019. Just previous to that, Panasonic had stated solid-state cells weren’t going to reach till 2028 or later. Panasonic has after all additionally been a longtime enterprise associate with Tesla.
Toyota has confirmed at a few factors that the tech is beneath improvement and scheduled for a manufacturing mannequin across the center of the last decade. Earlier this 12 months it revealed the primary software might be a hybrid, not an EV.
