It home on August 26, it was reported that Huawei Technologies Co., Ltd. announced on August 25, 2020 a patent for an elastic current collector and its preparation method, battery electrode plate and flexible lithium-ion battery. The patent application time was December 6, 2016. < / P > < p > it house understands that the patent abstract shows that the invention provides an elastic collector fluid, including an elastic polymer substrate and a conductive layer arranged on the elastic polymer substrate, the conductive layer has a folded structure, and the conductive layer material includes metal and/ The elastic collector has high flexibility and high cycle stability. When the elastic collector is used in the preparation of lithium-ion battery electrode sheet, the phenomenon of “powder drop” caused by mechanical deformation of electrode sheet and internal expansion of active material can be effectively avoided. The invention also provides a preparation method of the elastic collecting fluid, a battery electrode piece adopting the elastic collector and a flexible lithium-ion battery. gather and watch!
