Solid electrolytes are very important next step in the li-ion development. And specifically ones with stable anodes. Not li-metal ones that is.
When the whole cell is solid there’s just intercalation going on in every stage when the ion moves. Meaning there is no chemical decomposition happening. And what that means? Li-ion cells with +50 year life expectancy. What’s nuts about this is that we’re witnessing significant price drop at the same time lifetime keeps growing. For EV that’s nice but for grid tied energy storage this is the major driver for exponential market growth. BESS segment will be 10x compared to automotive. At some point EV’s will start enjoying the scale up benefits and prices keep dropping. Raw material cost of a functional LFP cell is around $8/kWh. We’re heading to that level before 2035. Literature is vast and probably most can be absorbed from scientific papers online. The Limiting Factor youtube channel is also nice source. Jordan really puts plenty of effort to get facts to viewers. https://youtube.com/@thelimitingfactor -Jukka to 15.12.2022 klo 0.07 Lawrence Winiarski <lawrence_winiar...@yahoo.com> kirjoitti: > > I'm not chemist, but I would suspect that batteries go "bad" for lots of > different reasons.
