Ciesla Abstract. A solid‐state lithium‐ion battery, in which all components (current collector, anode and cathode, electrolyte, and packaging) are stretchable, is introduced, giving rise to a battery design with mechanical properties that are compliant with flexible electronic devices and elastic wearable systems

A lithium-ion battery or Li-ion battery is a type of rechargeable battery.Lithium-ion batteries are commonly used for portable electronics and electric vehicles and are growing in popularity for military and aerospace applications. A prototype Li-ion battery was developed by Akira Yoshino in 1985, based on earlier research by John Goodenough, M. Stanley Whittingham, Rachid Yazami and Koichi. An improved current collector for use with lithium ion batteries includes an aluminum grid of the type used for making conventional current collectors that is plated with a layer of zinc, the outermost portion of which is oxidized to zinc oxide. The current collector is made by first cleaning an aluminum grid in an aqueous basic solution to remove its outer layer of alumina The primary current-collector materials being used in lithium-ion cells are susceptible to environmental degradation: aluminum to pitting corrosion and copper to environmentally assisted cracking. Localized corrosion occurred on bare aluminum electrodes during simulated ambient-temperature cycling in an excess of electrolyte
