Electrochemical energy storage devices
摘要
說(shuō)明書(shū)
Like batteries, the solid-state energy storage devices and systems described herein make use of conduction of ions through an electrolyte. For example, the disclosed energy storage devices and make use of reversible redox reactions that take place at the electrodes with ions that pass through the electrolyte. In the disclosed energy storage devices, these reversible redox reactions can occur without limit, and permit full discharge without damage. In some embodiments, an energy storage device comprises a simple construction, where two electrodes are separated by a solid-state electrolyte.
B. Temperature
Unlike battery chemistries such as lead/acid and lithium-ion, energy storage devices described herein are not restricted by temperature and remain capable of operating within a wide range of temperatures, such as, for example between about ?100° C. and about 700° C., although some embodiments may exhibit a certain amount of temperature sensitivity. It will be appreciated that the energy storage devices of some embodiments can withstand this temperature range due to the use of ceramic electrolytes instead of liquid, gel, or polymer electrolytes. It will be appreciated that the ceramic materials used as electrolytes herein are not commonly seen to represent electrolytes at ambient temperatures when in bulk, but rather as dielectrics through which neither electrons nor positive ions can move.
