Lithium- Ion batteries were proposed by M Stanley Whittingham, at Binghamton University, while working for Exxon in the 1970s.So Lithium battery technology to begin research in the 1970s , which at that time is a type of single-use disposable or primary cell. special properties of lithium- Ion batteries. It’s a lightweight metal , high voltage and the highest energy density equal weight. But The first problem of lithium metal (Lithium metal) is safety between charging
Research in the past has been changed from experiments using lithium in metal more secure than the ions.
