The latest research results of solid polymer lithium battery

Source: 2020 - 04 - 10 when hits: recently, the latest research results of solid polymer lithium battery, the Chinese Academy of Sciences developed a solid polymer lithium-ion batteries, the research was published in the journal. With the continuous development of the electric car industry, the demand for high power output and the safety of lithium-ion batteries is increasing. The electrolyte membrane material is one of the reasons for the lithium battery industry rapid development. The development of new polymer electrolyte and safety film materials is particularly important to improve the dynamic performance of lithium-ion batteries. Through long-term efforts, China's scientific research personnel to use their related intellectual property rights, such as functional changes, wet the manufacture, the interface coupling, etc. , developed the high voltage, high security of dynamic lithium battery diaphragm. The diaphragm has a good flame retardant, high temperature resistance and good electrolyte invasive, greatly improving the safety and performance of multiplier of lithium-ion batteries. Polymer battery traditional liquid lithium batteries are made from polyolefin film and combustible carbonate solvent. With flame retardant fiber as the basic raw material, through functionalization modified predictor, the preparation of a kind of good plastic performance of solid polymer electrolyte. Compared with traditional solid electrolyte, the electrolyte has higher mechanical strength, better charge-discharge performance, a wide applicable temperature range, it has great industrial value and development prospects. At present, Chinese researchers are trying to optimize all kinds of industrial parameters, hope the battery can be applied in the economical electric car industry.
