Not all lithium ion batteries are the same. In fact, there are a variety of different lithium ion chemistries. Many lithium ion batteries contain cobalt. Cobalt is the element responsible for thermal runaway, fires and overheating that have been reported in homes, businesses, on airplanes, laptops, cellphones and hover boards and even in utility-scale installations. Cobalt is toxic, unstable and hazardous. SimpliPhi does not use cobalt. Our lithium ion chemistry is lithium ferrous phosphate (LFP). LFP is environmentally benign, does not pose a danger of thermal runaway and is non-toxic.
