Patent number: 12009494Abstract: Systems and methods in which a thermal conductive composite comprises a non-uniform heat absorption profile of a thermal reactive material are described. Thermal conductive composites herein may be utilized in thermal regulatory modules with a gradient structure configured to transfer heat energy away from an area near a heat source to an area with a relatively large latent heat absorbing capacity. Thermal conductive material may be provided in a frame structure having lower porosity in a first region more near a heat source and higher porosity in a second region more distant from the heat source. A thermal reactive material may be deposited so as to be disposed within the pores of the thermal conductive material frame structure wherein the density of the thermal reactive material in the first region of the thermal conductive composite is lower than that at the second region of the thermal conductive composite.Type: GrantFiled: January 19, 2021Date of Patent: June 11, 2024Assignee: Hong Kong Applied Science and Technology Research Institute Co., Ltd.Inventors: Jing Xiang, Pau Yee Lim, Laiyong Xie

Patent number: 9431643Abstract: The present disclosure relates to a separator of a lithium-ion battery and a preparation method thereof, the separator comprises a substrate membrane and a coating provided on a surface of the substrate membrane, the coating comprises ceramic particles, an adhesive and a solid polymer wax which has a melting point of 85˜120° C., a molecular weight of 1,000˜25,000 and a particle size of 0.5˜10 ?m. When the lithium-ion battery is heated due to overcharge and the like to make the interior temperature reach the melting point of the solid polymer wax, the solid polymer wax can be melt and enter among the ceramic particles and into the micropores of the substrate membrane by capillarity so as to function as electrical disconnection, which can effectively cut off the channel of the lithium ions and stop the overcharge, and ensure the safety performance of the lithium-ion battery under the situation of overcharge.Type: GrantFiled: April 15, 2014Date of Patent: August 30, 2016Assignee: DONGGUAN AMPEREX TECHNOLOGY LIMITEDInventors: Xulun Lai, Xinzhi Zhang, Qian Xiu, Yaoming Deng, Laiyong Xie, Hui Jiang, Ying Wang
