Solar power ustc imitation pearl improve lithium battery shock resistance

Porous polyolefin because of their excellent electrochemical stability and is widely used as commercial lithium ion battery diaphragm, as the battery is against short circuit between the cathode of isolation layer, solar energy, polyolefin diaphragm plate heat exchanger type parameters greatly affect the security performance of the battery, heat dissipating capacity of heat storage tank, especially when there is outside of the local impact of diaphragm. The research results show that the polysilicon prices imitation nacre layer of the diaphragm to the battery has a good protective effect and can effectively reduce many safe hidden trouble. Polysilicon prices in response to external shocks, imitation nacre coating by patches of the effect of slip effectively expand stress area to dissipate the impact stress, thus effectively protect the diaphragm internal pore structure, maintain uniform inside the battery of lithium ion flow. In order to further confirm the pearl layer inspired the diaphragm effect about the safety of commercial battery, solar energy equipment, the team of two kinds of impact test of soft package battery diaphragm assembly. We have heard from China university of science and technology: this school team inspired by pearl layer has high toughness, imitation nacre layer diaphragm improve lithium battery shock resistance. The work proposed toughening diaphragm strategy, build imitation pearl layer plate heat exchanger type and parameters from the theoretical simulation and experimental tests prove its ability to improve lithium battery shock, solar photovoltaic (pv) network, which will enhance the safety of lithium-ion batteries for the future open up new ways. Team in the deep understanding of the nature mother of pearl high toughness principle, on the basis of the PE membrane surface layer build imitation pearl & other Mud brick & throughout; Ordered structures. The team through constructing imitation pearl in polyethylene membrane surface coating, monitoring and control system of explain effectively maintain the diaphragm within the pore structure after impact, so as to ensure the battery charge and discharge process of lithium ion flow with uniform. Monitoring system of the composition of the interpretation of the research team continues to investigated is impacted by the two soft package after the long cycle of the battery performance, the use of imitation nacre coating of the diaphragm in the soft package in the circulation of more than 80 battery still showed good stability. Recently, the university of science and technology of China, photovoltaic power station NiYong Yao Hongbin professor and professor shu-hong yu team inspired by pearl layer has high toughness, this paper proposes a method of impact toughness reinforced polyolefin diaphragm. Relative to use commercial ceramic diaphragm soft package of the battery, solar net, photovoltaic power station adopts the imitation pearl layer of the diaphragm soft package battery performance impact in the smaller change of open circuit voltage and good cycle stability and high security.
