CHINA OVERCOMES KEY BARRIERS TO UNLOCKING ALL-SOLID-STATE EV BATTERIES WITH 1,000 KM RANGE

Summary from the TLDR newsletter

Chinese scientists have achieved three breakthroughs that could be key to unlocking all-solid-state batteries. The first is iodine ions, which actively attract lithium ions in the interface between the electrode and the electrolyte, plugging the gaps and enabling a better bond. The second is a polymer material that can be bent 20,000 times and twisted into a twist without breaking. The third is a type of 'shield' on the electrolyte surface that passes needle penetration tests and can handle temperatures of over 120 degrees Celsius. The breakthroughs could result in a 100-kilogram battery pack that delivers over 1,000 kilometers of range.
