Abstract

The present disclosure relates to an all-solid-state battery with improved lifetime and an operating method thereof. Specifically, the all-solid-state battery includes a laminate including a unit cell provided with an anode, a cathode, and a solid electrolyte layer interposed between the anode and the cathode, and an expansion layer positioned on at least one surface of the laminate, and expanded by at least any one change in voltage and temperature.

Description

technical field [0001] The present disclosure relates to an all-solid-state battery with increased lifetime and a method of operating the same. Background technique [0002] Chargeable and dischargeable lithium secondary batteries are used not only for small electronic devices such as mobile phones or notebook computers, but also for large transportation devices such as hybrid vehicles or electric vehicles. Therefore, there is a need to develop secondary batteries with higher stability and energy density. [0003] Since a conventional lithium secondary battery is mainly based on an organic solvent (organic liquid electrolyte) to constitute a single cell (cell), it is limited in improving stability and energy density. [0004] Meanwhile, all-solid-state batteries using inorganic solid electrolytes are based on technologies that do not include organic solvents, so safer and simpler single cells can be manufactured, and thus all-solid-state batteries using inorganic solid elec...
