Sorry if this is a silly question, but what are the moving parts that make normal lithium ion batteries not solid state?
Phones and laptops don't make any noticeable movement sounds when they charge, but I have noticed that my Tesla will produce some random knocking sounds when supercharging. Are these the kinds of moving parts that solid state batteries would remove?
- adgjlsfhk1 4y agoThe sound your car makes when charging are temperature control stuff (fans, valves, cooling pumps etc). "solid state" for batteries isn't opposed to moving stuff, but liquid stuff.

- sanxiyn 4y agoIt's not about moving parts. All current lithium ion batteries use liquid electrolyte.
- jxramos 4y agoI'd suspect the knocking sounds are thermal expansion of some rigid parts shifting about.
- monocasa 4y agoIn this case solid state refers to replacing the electrolyte gel with a solid material. That gel can move out of the way as dendrites grow within the cell causing short circuits between the anode and cathode layers.
- panick21_ 4y agoThey still have liquid gel. The just have a solid separator and the gel is only on 1 side of the battery.
