THREE-DIMENSIONAL SOLID STATE BATTERY

摘要

The present invention relates to a battery in which both electrodes and the electrolyte are solids which is called a solid state battery. Solid electrolytes are a class of materials also known as superionic conductors and fast ion conductors, and their study belongs to an area of science known as solid-state ionics. As a group, these materials are very good conductors of ions but are essentially insulating toward electrons, properties that are prerequisites for any electrolyte. The high ionic conductivity minimizes the internal resistance of the battery, thus permitting high power densities, while the high electronic resistance minimizes its self-discharge rate, thus enhancing its shelf life. Solid-state batteries generally fall into the low-power-density and high- energy-density category. The former limitation arises because of the difficulty of getting high currents across solid-solid interfaces.
