This is according to a Nikkei Asia study that also states the global solid-state scene is dominated by Japanese players, with South Korean companies following at some distance. The source notes that Toyota\u2019s lead comes thanks to the multitude of patents it holds, an impressive 1,331, followed by Panasonic with 445 patents and Idemitsu Kosan with 272 patents (mainly related to the metals that go into this type of batteries); Samsung is in fourth spot<\/a>.<\/p>\n 13<\/span> Photos<\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n It\u2019s worth noting that Toyota and Panasonic are working together on solid-state batteries<\/a>, after they set up a joint venture in 2020. The automaker apparently increased the number of patents it held between 2016 and 2020 by 40 percent.<\/p>\n Toyota<\/a> plans to install its first solid state battery in a hybrid due to be launched in the next few years. We haven\u2019t had any confirmation of previous reports which stated that the next-gen Prius would be the first commercially available car with a solid-state battery, but it still seems like a solid bet.<\/p>\n The concept that previews Toyota\u2019s first solid-state EV, the crossover that the carmaker said it would unveil in 2021, will probably be shown in the not too distant future, although the production model will probably only arrive after the middle of the decade. The main factor preventing solid-state tech from becoming mainstream is, of course, cost.<\/p>\n Korean corporations are gaining ground, according to the source. There is also a multitude of other companies doing solid-state battery research, with the most recent player being Vietnam’s VinFast<\/a>, which recently announced it was going to invest in a battery startup called ProLogium<\/a>.<\/p>\n![\"2019](\"https:\/\/cdn.motor1.com\/images\/static\/16x9-tr.png\")
