The 9.65 number is nonsense,
The 9.65 number is nonsense, nobody is claiming anything like that for solid-state batteries. Metal air batteries have shown numbers like that but so far no one has figured out how to build one that has the durability that would be necessary. The tone of the article that lithium ion batteries are an extreme fire hazard is also objectionable. Yes they can catch fire but it hardly ever happens, gasoline fires are an order of magnitude more likely to happen. The inherent safety of solid state batteries will make a big difference mostly because it will reduce the costs associated with protecting the batteries and 0 fires is better than a few fires. But the author deliberately exaggerated the risk.
