Electric battery e.g. lithium-ion electrochemical type rechargeable battery, for e.g. electric motor vehicle, has device with phase changing material having eutectic mixture including specific solid liquid transformation temperature

摘要

The battery has a temperature conditioning device with a quantity of a phase changing material comprising an eutectic mixture, whose solid liquid transformation temperature is between 35 and 45 degrees. The material is placed in a can such that the material contacts a part of a surface of the casing. A cell (1) has a casing (2) in which an electrochemical system insulates chemical components for electricity generation. The casing has a battery terminal (3) branched on electrodes of an electricity generator system.
