Electric Car Batteries Safer Than Used in Boeing Dreamliner
Boeing’s (NYSE:BA) Dreamliner battery woes are casting a dark shadow on the electric car industry’s reliance on lithium batteries. The safety of lithium-based batteries has been routinely called into question by critics who believe the widespread adoption of the electric car is a Jetsonian fantasy whose time will never come.
Some of those critics have further railed against the use of lithium batteries in electric and hybrid vehicles using the revelation that lithium-cobalt oxide, the type of lithium cell chemistry used in the 787 Dreamliner, is also used in the Tesla Roadster and Model S automobiles. However, most electric car manufacturers have opted to use batteries based on lithium-manganese oxide, and to a lesser degree, lithium-nickel-manganese-cobalt oxide and lithium-iron-phosphate chemistries, as laboratory testing shows these are the safest in high-temperature applications. Lithium-manganese batteries may have lower energy density, but compared to lithium-cobalt batteries, they last longer and hold up better when damaged.
