The urge to make more energy-dense batteries is not new. On the contrary, it is getting more frequent to hear how crucial it is to make lighter and cheap.
One of the breakthroughs the Tesla 4680 cells were supposed to have was dry battery electrode (DBE) coating. This process would eliminate N-Methyl-2-pyrr.
QuantumScape continues its slow but constant progress with its solid-state cell platform. After disclosing some test results and getting critics to doubt them, the company asked Mobile Power Solutions to test its single-layer cells. The results are even better than the ones the company disclosed in December 2020.
One of the main arguments in favor of solid-state batteries is that they would be way safer than the current ternary cells. Solid Power wanted to prove that with its batteries and put them to third-party testing. After being perforated with a nail, overcharged, and submitted to a short circuit, Solid Power cells did not catch fire in any situation.
