Abstract
A casing for the thermal management and protection of an electrochemical cell, the casing comprises a first material, an inner surface configured to be in physical contact with an electrochemical cell, wherein the inner surface is substantially solid at room temperature; and a polymer matrix dispersed within the first material and comprising two or more temperature management materials. At least one of the two or more temperature management materials comprise a phase change material having a latent heat of at least 5 Joules per gram and a transition temperature between 0° C. and 100° C., and an elastomeric material. The polymer matrix is substantially homogeneous, and in an environment where the electrochemical cell and a second electrochemical cell operate under the same charging and discharging conditions, the casing reduces a first operating temperature of the electrochemical cell by at least 10° C.
