"We supplied samples to customers from the end of last year to the beginning of this year and are receiving positive feedback," Samsung SDI VP Koh Joo-young said at SNE Battery Day 2024 in Seoul, according to Korean outlet The Elec and translated by Google." This would be more convincing if reviewers could order samples. Yoshino seemed to be shipping a solid state battery, but several people have bought and disassembled the thing, and it has liquid/gel components. That was disappointing. CATL has some good comments.[1] Wu Kai of CATL was quoted as saying that the maturity level of the technology and the manufacturing process can currently be categorised at 4 on a scale of 1 to 9. CATL wants to be at 7 to 8 by 2027, which is equivalent to the production of solid-state batteries in small quantities. CATL also mentions that they have 1,000 people in R&D working on this. This is a big project in China. The China All-Solid-State Battery Collaborative Innovation Platform is getting government funding and has all the big battery makers in China on board.[2] Toyota's roadmap shows solid state batteries around 2028.[3] There are solid state battery announcements all over, but the big players all admit that the manufacturing is really tough. A US startup exists.[4] They mostly make press releases, not products.
