![]() These studies also increased interest in the commercialization of primary lithium-ion batteries. He observed the formation of a passivation layer that was capable of preventing a direct chemical reaction between lithium and the electrolyte while still allowing for ionic transport across it, which led to studies on the stability of lithium-ion batteries. In early 1958, Harris examined the solubility of lithium in various non-aqueous (aprotic) electrolytes-including cyclic esters (carbonates, γ-butyrolactone, and γ-valerolactone), molten salts, and inorganic lithium salt (LiClO 4)-dissolved in propylene carbonate (PC). SHE), it was quickly realized that lithium could serve well as a battery anode. Considering lithium’s excellent physical properties, such as its low density (0.534 g cm −3), high specific capacity (3860 mAh g −1), and low redox potential (−3.04 V vs. It was only a century later that Lewis began exploring its electrochemical properties. Lithium “lithion/lithina” was discovered in 1817 by Arfwedson and Berzelius by analyzing petalite ore (LiAlSi 4O 10), but the element was isolated through the electrolysis of a lithium oxide by Brande and Davy in 1821. ![]()
