摘要： In using silicone to control thermal runaway in a battery module for an electric vehicle, a mold is provided to hold a plurality of energy storage elements with spaces in between adjacent ones thereof. Substantially uncured silicone polymer mixture is injected into the mold to fill the spaces. During fill of the mold with the injected silicone polymer mixture, variation is introduced of one or more of: a ratio of constituents of the silicone polymer mixture being injected; at least one of a presence or absence of additive(s) in the injected silicone polymer mixture, type(s) of the additive(s) in the injected silicone polymer mixture, or concentrations of the additive(s) in the injected silicone polymer mixture; or mold temperature. Upon completion of the fill of the mold with the injected silicone polymer mixture, curing of the injected silicone polymer mixture is completed. Precise, fast cure of the silicone is achieved.

摘要： A thermal storage device for batteries is provided. In some examples, the thermal storage device is provided for a battery pack that includes one or more rechargeable battery cells. In some examples, the lithium ion battery cells are used. The thermal storage device is in thermal contact with the battery cell. The thermal storage device is made of a material that absorbs heat that is given off by battery cells during discharge. In some examples, the thermal storage device is made of a plastic material. The material has a relatively low thermal conductivity but a relatively high specific heat capacity, allowing heat energy to be stored in the thermal storage device. The thermal storage device prevents the battery pack from overheating during use. The thermal storage device defines one or more cell receiving volumes. In some examples, an axially extending relief volume is provided.

The core includes a first phase-change component and a second phase-change component. The first phase-change component is paraffin with a melting point of 37° C. to 42° C. The second phase-change component is paraffin with a melting point of 65° C. to 75° C. A melting point of the insulative heat-conducting wall material is greater than 75° C. A mass ratio between the first phase-change component and the second phase-change component is 35:(45 to 77). The phase-change microcapsule is applied to the battery in the form of a coating layer. The specified first phase-change component and second phase-change component of a specified melting point are mixed at a specified ratio in the core.
