Electrochemical energy storage devices
摘要
說明書
In embodiments, the solid electrolyte allows for migration of ions across the solid electrolyte, making the solid electrolyte suitable for use in an energy storage device. It will be appreciated that certain solid electrolyte materials may exhibit ionic conductivity properties at high temperatures, such as at temperatures of about 600° C., but the ionic conductivity decreases with temperature such that the solid electrolyte material is not ionically conductive at low temperatures, such as temperatures of 25° C. or even 50° C. Advantageous electrolytes for energy storage devices of the invention, however, maintain suitable ionic conductivity properties even at temperatures at which conventional batteries are useful, such between 0° C. and about 50° C., such as about 25° C. Unlike conventional batteries, the energy storage devices of the invention exhibit suitable properties at most temperatures commonly encountered by humans. For example, the solid-state electrolytes used in the energy storage devices may exhibit suitable ionic properties at temperatures as low as about ?50° C., as well as at temperatures as high as about 50° C. and higher.
