Tesla Model 3 production can only go as fast as the slowest part of the entire supply chain and production process. For months, the battery module line was their main production bottleneck.
This is an easy-to-make ionic liquid or deep eutectic solvent that I've made. Basically it's Epsom salt (magnesium sulfate heptahydrate) and glycerin/glycerol in a 1:3 molar ratio.
The gigafactory will cost Tesla up to $5 billion to build. It will produce 35 GWh/yr in battery cells and 50 GWh/yr in battery packs. Expansion plans are targeting 105 GWh of annual capacity by 2020.
The most difficult problem with off-grid living, solar, and wind power systems is the batteries. Traditional lead batteries are cheap but low quality and die quickly in the cold. What if a battery existed that could run for 100 years, run in any kind
Some Tesla observers are convinced that it will be a battery, based on the design that powers the company's automobiles, yet large enough to keep the lights on at a home.
