Past life of lithium-ion battery

The lithium-ion battery is a rechargeable battery that relies on lithium ions to move between the positive and negative electrodes to work. Lithium-ion batteries use an embedded lithium compound as an electrode material. Currently used as positive electrode materials for lithium-ion batteries are lithium cobalt oxide (LiCoO2), lithium manganate (LiMn2O4), lithium nickelate (LiNiO2) and lithium iron phosphate (LiFePO4).

The first to propose the concept of lithium-ion batteries was M.S. Whittingham, who worked at Exxon in the 1970s and now works at Binghamton University. He used titanium sulphide as the cathode material and lithium metal as the anode material to make the first lithium-ion battery, and the safety risk has been accompanied by lithium-ion batteries at this time - just under normal atmospheric conditions. As long as there are water and oxygen, the fiery character of lithium will be revealed, and the chemical reaction will follow.
