    You mean panasonic battery, made by tesla with leased panasonic equipment.

    Nobody wants to hear this but that is a seriously low tech battery. Toyota is working on solid state batteries that will give over five times the range of current lithium ion batteries. If Toyota develops that it will put tesla out of business.

    A battery has more elektrons on the negative side so how could the positive side hold the power?

    *This battery reconditioning program exceeded my presumptions [ check Details Here>>>**bit.ly/2pDTMw1** ]. It worked on any drill battery, several AA and AAA batteries, and any camera battery. The steps are simple and the act itself is exciting to do. No matter what type of battery you`ve got, it is sure to function again!*

    Why not unroll what's inside the batteries and stack it like a 3 feet by 4 feet square batterie ? You take more space with this kind of batterie and you add more weight with the exterior finishing. Sorry for my poor english lol

    Most of what he says is incorrect. Black = carbon with Li atoms stored in it. The copper foil is the current collector. The electrolyte is most definitely not solid.

    US doesn't have a very large supply of lithium, it's mostly China (imagine that) in addition to other countries including areas in South America. batteryuniversity.com/learn/article/availability_of_lithium Also mentioned in this article is the need for rare earth magnets, again China controlling about 95% of the market of REM.

    That "carbon fiber" retainer is NOT carbon fiber. If it was, it could very easily short the battery. It is a fiberglass retainer (hence the white fibers/yellow resin). Also... stating "it is completely safe" is VERY FALSE!!!! EDIT THIS VIDEO SO MORE PEOPLE DO NOT DO THIS!!!!
