    Abstract: A thermal barrier component for an electrochemical cell according to various aspects of the present disclosure includes a functional material. The functional material includes at least one of a hydrate of a metal carbonate and a hydrate of a metal phosphate. The functional material is configured to release water vapor at a first temperature of greater than or equal to about 100° C. and decompose to release a gaseous fire retardant at a second temperature of greater than or equal to about 300° C. Another thermal barrier component according to various aspects of the present disclosure includes a hydrate and a fire retardant. The hydrate is configured to release water in an amount greater than or equal to about 1 kg at a first temperature of greater than or equal to about 100° C. The fire retardant is configured to decompose at a second temperature of greater than or equal to about 300° C.
