Why lithium ion batteries burn or even explode?

Leave a Comment / Safety Standard / By

Introduction Lithium ion batteries are compact, lightweight batteries that hold considerable charge and fare well under constant discharge-recharge conditions. The batteries are found everywhere — in laptop computers, cameras, cell phones, and electric cars. Although accidents are rare, those that do occur may be spectacular, resulting in an explosion or fire. It can be seen that, theoretically, a …
