Abstract
Provided herein are energy storage devices. In some cases, the energy storage devices are capable of being transported on a vehicle and storing a large amount of energy. An energy storage device is provided comprising at least one liquid metal electrode, an energy storage capacity of at least about 1 MWh and a response time less than or equal to about 100 milliseconds (ms).
Claims21
An electrochemical energy storage device, comprising:
- (a) a container comprising an electrically conductive housing, a reactive material, and an electrolyte comprising a salt, wherein said salt is in a liquid or a gas state during operation of said electrochemical energy storage device;
- and
- (b) a sealing unit configured to seal said container from an environment external to said container, wherein said sealing unit comprises a ceramic material exposed to said reactive material or said salt, wherein said ceramic material comprises an element capable of forming a compound with said reactive material, and wherein said sealing unit provides a helium leak rate of no more than about 1×10−6 atmosphere-cubic centimeters per second (atm-cc/s) at a temperature of at least about 200° C.
