China-certified solid state, CATL sodium, and ProLogium are manufacturable batteries that don't violently deflagrate under puncture, cutting, or high temperature.

When these reach markets in significant quantities, most Li ion (NMC, LiPo, and LFP) with liquid electrolyte or plastic separators should be banned for most purposes, especially vehicles and occupied areas. These are whale oil lamps that pose a silent, ubiquitous danger to life and property.

Solid state batteries are offering a lot of tagline benefits: safety, high energy density, lightweight...amongst many other claims. However, there are a number of things you need to be aware of: 1. Safety - cannot be completely safe 2. Pressure - some solid state cells need pressure applied and this can be quite high and impact claimed density 3. Liquids - some cells call their technology Semi-Solid, this is not solid state, let's not be caught out
