Number 6 is important to reinforce with interior crews


Lithium ion batteries overheat when the liquid electrolyte evaporates. This allows the electrodes to contact one another creating a short circuit. A thermal runaway can be produced by the quick discharge of stored electricity.
Heat vents or flame-retardant electrolytes may help, but they degrade performance. Now, Chinese researchers may have developed an effective circuit breaker. They use a shape-memory polymer with a copper coating on top as a conductor. When the temperature hits 197*F, the polymer expands and permanently breaks the circuit.

Elsewhere, engineers have developed a robot to automate the testing of novel electrolytes for batteries. It uses computer software with artificial intelligence machine learning to speed up the process of sorting through billions of electrolyte ingredients. The primary goal is improving charging times, but can also learn to consider total life cycles, power output, and safety.
