General Motors Co. said a lithium-ion battery undergoing tests exploded Wednesday at a GM research center in Warren, Mich., injuring at least seven employees.
Eighty other employees were forced to evacuate GM's Warren Technical Center after the battery exploded during morning work hours. Two were sent to the hospital.
GM spokesman Greg Martin told Fox News all damage was confined to the lab, which is equipped with blast doors and windows for just such an occurrence. Warren Mayor Jim Fouts said GM "had extreme testing going on," Fox News reported, and admitted major damage was done to the building housing the lab.
According to autoblog.com, the fire department told Mayor Fouts the explosion was caused by fumes from hydrogen sulfide. When asked to comment, GM declined. An investigation is underway.
