Electric vehicle fires often become big news stories, but what actually causes them? A chain reaction inside the battery—called thermal runaway —causes the battery to generate excess heat and catch fire. Regulations have been put in place so that once a thermal runaway issue has been detected in the battery pack, occupants of the car… Read more »

MIT chemists develop an organic battery cathode for EVs
MIT researchers have designed a new lithium-ion battery using an organic cathode that contains no cobalt or nickel. In a new study, the researchers showed that this material an conduct electricity at similar rates as cobalt batteries, and could be produced at much lower cost. The new battery also has comparable storage capacity and charges… Read more »
SAE International forms committee to develop standard for energy-efficient and sustainable EVs
