The conventional Li-ion cell burst into flames, but our silicon Li-ion cell did not. To fabricate the Enovix battery, we begin with a wafer of silicon that’s 1 millimeter thick. This doesn’t
Lithium batteries are over 95% efficient. This means they can use 95% of the energy they store. If you have 100 watts coming into a battery, you have 95 watts available to use. Batteries with higher efficiency charge faster. Lithium batteries can take a faster rate of current which means they charge quicker than lead-acid which overheats if you Lithium Ion. Lithium Ion (Li-Ion) cells have a negative electrode (anode) made from lithium compounds. Lithium is a highly reactive material and is much lighter than the hydrogen-absorbing metal alloy of the NiMH negative electrode. This leads to higher gravimetric energy densities for the Li-Ion cell.Cells can stay in storage for 12 months
But a car's 60~100Ah 12V battery is way more dangerous than a cell phone 3800 mAh because the car's simply has more energy. Of course big fat li-ion batteries do exist, but they are usually safer nonetheless because they tend to have a) safer connectors and/or b) built-in overdischarge protection.

The big difference is that capacitors store power as an electrostatic field, while batteries use a chemical reaction to store and later release power. Inside a battery are two terminals (the anode and the cathode) with an electrolyte between them. An electrolyte is a substance (usually a liquid) that contained ions.

Lithium-sulphur. Lithium-sulphur technology has the potential to offer cheaper, lighter batteries that also offer safety advantages. After initially finding use in niche markets such as satellites, drones and military vehicles, the technology has the potential to transform aviation in the long term.
