Our technological level to produce a solid-state battery for smartphones will be mature enough in one to two years. However, it depends on Samsung Electronics whether it will be used for phones," said one anonymous Samsung SDI exec to Korean media, and, given what the technology promises, the adoption might be a no-brainer. Solid-state batteries eschew the liquid electrolyte of the current lithium packs for a material that can't leak, cause a reaction and burst into flames spontaneously."
According to Choi Jung-deok, an analyst at LG Economic Research Institute: "Solid-state batteries are a realistic alternative to lithium-ion batteries in solving the chronic safety issue as the development has been relatively faster than other next-generation batteries over the last 10 years." LG is also in advanced stages of development of such juicers, added Samsung's SDI exec who talked to the media about the state of the solid-state batteries, so we might see Galaxy S-series and G-series with worry-free battery packs in time for the S9 or the G7 even.
