Review of Solid-State Battery Technology Progress

Battery development is essential to satisfy the green technology trend that requires electric-based technology. Lithium-ion battery (LIB) is the most popular battery that has been used in various electric technology. However, LIB has a concern on the safety aspect by using liquid electrolyte which is prone to thermal failure that leads to flame or explosion. Solid- state battery (SSB) recent development could handle such thermal problems due to the non-flammable characteristic of the solid electrolyte. SSB also has potential for future main battery candidates due to high energy & power density. Although there are many advantages, SSB also has several problems in recent development. Interfacial stability, low ionic conductivity on room temperature, mechanical properties, etc. need to be studied further to make an adjustment for further development. This review would give information regarding recent progress on SSB development from various types of electrolyte and failure mechanisms.
