Solar power in our country scientists imitate mussel and developed the 'bruise' lithium battery protective material

The journal of top academic field of international materials of advanced materials has published the results. Recently, professor USTC joining NiYong Yao Hongbin, boiler heat storage in power plants and the bionic mother-of-pearl shu-hong yu research team, in the polyethylene membrane surface construct a & other; Layers of mud brick & throughout; The structure of the new materials. Recently, solar energy, photovoltaic contracting to install the pricelist university of science and technology of China scholars gleaming mother-of-pearl layer in the shell nature inspired, bionic build give a kind of new type & other; Imitation nacre layer throughout the diaphragm &; Protection material, the experiment shows that can effectively reduce the impact when the possibility of a lithium battery short-circuit, enhance security. On the market at present the mainstream commercialization of lithium-ion batteries, China solar energy network, widely used in porous polyolefin material as battery diaphragm for protection. Network monitoring solution offer experiments have shown that using commercial diaphragm protection material of lithium battery, boiler heat storage when hit by instantaneous voltage fluctuation amplitude was 60%, and the use & other; Imitation nacre layer throughout the diaphragm &; Material to protect the battery voltage fluctuations under 20%, and the voltage recovery faster. When the diaphragm by external shocks, the pore structure is very easy to deformation, cracking, leading to the inside of the battery ion flow disorder, joining and short circuit or even fire explosion in power station. ” Yao Hongbin professor introduction, solar panels, experiments show that this new material has better protective effect on batteries, and its production cost is not high, solar photovoltaic (pv) network, coating thickness and existing business materials, has good application prospect. At present, the research team has applied for patent. Photovoltaic power generation project of electric vehicles as a car accident collision, contracting installation price list may cause on-board lithium-ion battery fire explosion. “ Like a punch on the cotton, the new material can put stress on both sides to dissipative structure, unique solar net, conduction to the impact of the internal is reduced. The mother of pearl inside the clam shells in the nature, is a kind of & other; Hard and do not break tenacity & throughout; The excellent performance of materials.
