Solid-state battery patent

Who has a patent on solid-state batteries?

Toyo Kohan’s patent on solid-state batteries is co-filed with Toyota and is related to a sulfide all-solid-state battery. Nippon Denko’s patents on solid-state batteries are related to a garnet lithium ion-conductive oxide material with high ionic conductivity.

What is a solid state battery?

According to one embodiment, a solid state battery is disclosed. The method is performed in a moisture-free inert atmosphere. The method includes combining unreacted solid electrolyte precursors to form a green sheet. The method further includes stacking the green sheet in between porous electrodes to form a solid state battery.

Does knowmade patent solid-state Li-ion batteries?

That is why KnowMade is monitoring patenting activity on solid-state Li-ion batteries to complete its two recent reports on solid electrolytes for Li-ion batteries and solid-state Li-ion batteries with inorganic solid electrolytes.

Who invented solid-state batteries in 2022?

Several American companies entered the patent landscape in 2022, with the first patent on solid-state batteries being published that year. These companies include material manufacturers Ntherma, Zymergen, Ascend Element, PIDC, NEI Corporation and Huntsman, as well as the battery manufacturer EnPower Greentech.

Are solid-state batteries patentable in Japan?

Even though most Japanese companies had started filing patents on solid-state batteries many years earlier, some of them only joined the IP landscape in 2022, such as material manufacturers (Toyo Kohan, Nippon Denko), battery manufacturers (Prime Planet Energy & Solutions, Vehicle Energy Japan) and OEMs/end users (Futaba, Tripod Design, Softbank).

What makes pure lithium a solid state battery?

Its patent on solid-state batteries is related to lithium containing nano powders and/or mechanical alloys containing garnet solid electrolytes and their manufacturing methods. Pure Lithium, established in 2019, commercializes lithium metal negative electrodes.
