A solid-state battery (SSB) is an electrical battery that uses a solid electrolyte for ionic conductions 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. OriginBetween 1831 and 1834, discovered the solid electrolytes and, which laid the foundation for. 1900s-2009 Solid-state batteries are potentially useful in,,, and. Electric vehicles and have used a variety of battery technologies, including Improved energy densitySolid state batteries offer the potential for significantly higher compared to traditional lithium-ion batteries. This is largely due to the use of lithium metal anodes, which have a much higher charge capacity. • • Cymbet• Ilika• Ionic Materials• LG• Panasonic (SSEs) candidate materials include ceramics such as, , sulfides and. Mainstream oxide solid electrolytes include Li1.5Al0.5Ge1.5(PO4)3 (LAGP), Li1.4Al0.4Ti1.6(PO4)3 (LATP), perovskite-type Li3xLa2/3-xTiO3. CostThin-film solid-state batteries are expensive to make and employ manufacturing processes thought to be difficult to scale, requiring expensive equipment. As a result, costs for thin-film solid. BackgroundThe earliest thin-film solid-state batteries is found by Keiichi Kanehori in 1986, which is based on the Li electrolyte. However, at that time, the technology was insufficient to power larger electronic devices so it was not fully developed.
