Research on new separator materials for 3.7V Lithium Polymer Battery—PI separators
Research on PI separator, a new separator material for 3.7V Lithium Polymer Battery. Polyimide (PI) has good thermal stability, chemical stability and outstanding mechanical properties. Its long-term use temperature can be as high as 300°C. It is the thin film insulation material with the best comprehensive performance today. PI separators are regarded as the next generation separator material to be developed due to their excellent thermal stability and good electrolyte absorption and retention properties, providing better safety protection for power lithium batteries.
3.7V Lithium Polymer Battery are mainly composed of positive and negative electrode materials, electrolytes and separators. There is a membrane material between the positive and negative electrodes of 3.7V Lithium Polymer Battery, usually called a separator, which is an important part of 3.7V Lithium Polymer Battery. There are two main methods for preparing lithium-ion battery separators: melt stretching and thermally induced phase separation.
Research on new separator materials for 3.7V Lithium Polymer Battery—PI separators
PI refers to a type of polymer containing polyamide rings in the main chain. It is one of the organic polymer materials with the best comprehensive properties. Its high temperature resistance is above 400℃, and its long-term use temperature is between 200 and 300℃. It has no obvious melting point and high insulation performance. The dielectric constant at 1000Hz is 4.0 and the dielectric loss is only 0.004~0.007. It belongs to F to H class insulation. Material. It has been widely used in special fields, aerospace, microelectronics, nanometer, liquid crystal, separation membrane, laser and other fields.
As a lithium-ion battery separator, PI separators have many advantages compared with traditional polyolefin separators: first, it has good high temperature resistance and can improve the safety performance of 3.7V Lithium Polymer Battery; secondly, PI porous membranes have high porosity , and PI has a large number of polar groups, the separator has high ionic conductivity, and has very good wettability to the electrolyte, making the lithium-ion battery suitable for charging and discharging at high rates, shortening the charging time, and extending the use of the lithium-ion battery. life.
Therefore, PI separators are expected to serve as next-generation lithium-ion battery separator materials. In addition to being used to modify polyolefin separators with poor thermal stability, PI can also be used alone to prepare lithium-ion battery separators. Among various preparation methods for PI separators, electrospinning, template methods, and phase inversion There are more legal studies.
So far, research on PI separators at home and abroad has achieved many phased results, but most of them still stay in the laboratory research stage. In addition, there is a lack of related production equipment for PI lithium battery separators, and the material cost is high, resulting in the domestic market. There is still a big vacancy in PI lithium battery separators.
Therefore, polymer material companies need to find ways to reduce PI costs in monomer synthesis and polymerization methods. Separator production companies and equipment processing companies cooperate with each other to enable the early industrialization of PI lithium battery separators.
PI materials have good heat resistance, but are difficult to process. It is difficult to achieve mass production of PI separators at this stage. Therefore, the domestic separator industry needs leading companies to set an example.
