1. An energy storage system, the energy storage system comprising at least one storage cell, wherein the at least one storage cell is provided at least in sections with a casing, wherein the casing consists of plastic, wherein the casing is provided with a material for increasing a thermal conductivity, wherein the material is configured such that a thermal runaway in the event of a fault is reduced, and wherein the material for increasing the thermal conductivity is an endothermically acting material which is subject to an endothermic reaction at temperatures above 100° C. and reduces the thermal conductivity at temperatures above 100° C.
