A solid-state battery (SSB) is an electrical battery that uses a solid electrolyte (solectro) to conduct ions between the electrodes, instead of the liquid or gel polymer electrolytes found in conventional batteries. Solid-state batteries theoretically offer much higher energy density than the typical lithium-ion or lithium polymer batteries. 

In the present book, fifteen typical literatures about solid-state battery published on international authoritative journals were selected to introduce the worldwide newest progress, which contains reviews or original researches on solid-state battery. We hope this book can demonstrate advances in solid-state battery as well as give references to the researchers, students and other related people.
