Abstract
A battery includes a case having an interior holding an electrolyte activating one or more anodes and one or more cathodes. A cover is positioned on the case. The cover includes one or more quenching media that each has a phase transition that occurs at a temperature above a failure temperature of the battery and below a failure temperature of the battery. The failure temperature is the temperature at which a chain reaction associated with thermal runaway is initiated. The failure temperature of the battery is the temperature of the battery at which the thermal runaway causes failure of the battery.
Claims16
A battery, comprising:
- a case having an interior holding an electrolyte activating one or more anodes and one or more cathodes;
- a cover on an exterior of the case such that the case is positioned between the cover and the interior of the case, the cover including a quenching layer between the case and a support layer, the quenching layer including one or more quenching media dispersed in a first support,
- each quenching medium having a phase transition that occurs at a temperature above a exothermic reaction temperature of the battery and below the failure temperature of the battery,
- the exothermic reaction temperature being the temperature at which a chain reaction associated with thermal runaway is initiated, and
- the failure temperature of the battery being the temperature of the battery at which the thermal runaway causes failure of the battery.
