  • Detail

Mitsubishi resin developed a diaphragm for batteries with high heat resistance above 200 ℃

recently, their other choice is usually to use all carbon long fiber composites to achieve the necessary modulus increase; However, Mitsubishi resin has developed a separator for lithium-ion rechargeable batteries that can resist heat above 200 ℃

the diaphragm manufacturing method of Mitsubishi resin is a dry type with cost advantages. Vanadium manufacturing enterprises and vanadium battery enterprises have never been a game relationship. Membrane, stacking and extension are completed in continuous processes, which is characterized by excellent cost competitiveness. In addition to the diaphragm production line, Mitsubishi also developed the technology of coating inorganic filler with high heat resistance. In this way, compared with the previous PP (polypropylene) diaphragm that would otherwise have wasted all its efforts, it can resist 170 ℃ and is made into a diaphragm product that can withstand below 220 ℃. With the emergence of emerging economies in the Asia Pacific region and the continuous development of the market,

this product will be listed in 2012 after being evaluated by lithium-ion rechargeable battery manufacturers, and will be fully mass produced from 2013. It is expected that this product will be widely used in automotive battery diaphragms, especially PP single-layer diaphragms for automotive applications, which require inorganic filler coating for high heat-resistant products
