Introduction to the material structure of low-temperature polymer lithium battery

Many people do not know the composition of low temperature polymer lithium battery. Now Shenzhen Shmu New Energy Technology Co., Ltd. to introduce the specific basic technical knowledge of low-temperature lithium battery, so that you can better understand the characteristics of low-temperature lithium battery

The compaction thickness of the compound lithium-ion low-temperature lithium battery cathode sheet (3) is 53-82 m, The cathode active materials are one or several of lithium manganese oxide or lithium nickel cobalt manganese oxide or lithium cobalt oxide, The adhesive is polyvinylidene fluoride; The conductive agent is phosphorus sheet graphite, acetylene in 1500 ± 200m2 / g of the specific surface area, VGCF, CNF in one or several; The weight percentage of cathode active material: adhesive: scale graphite: acetylene: VGCF is 85-96:1-5:1-3:1-4:1-3; The compaction thickness of the negative sheet (5) is 56-62 m, The negative electrode active material is one or more of artificial graphite or intermediate phase carbon microspheres, Adhesive are one or several of polyvinylidene fluoride, SBR and CMC, Conducting agent is one or more of the conductive carbon black, VGCF, CNF; The weight percentage of the negative electrode active material: SBR: CMC: carbon black: VGCF is 85-96:1-5:1-3:1-4:1-3. Low temperature lithium battery is a polymer lithium ion low temperature battery with good discharge performance, large discharge rate, stable product performance, high specific energy and good safety.

Using & quot; tripole ear polymer low temperature lithium ion battery cell & quot;, & quot; a polymer lithium ion low temperature battery & quot; battery patent technology production of VGCF and (2000 ± 500) ㎡ / g activated carbon as additive and matching positive and negative material, injected with special electrolyte with special additives, ensure the lithium battery low temperature discharge function, while high temperature 70℃ shelved 24h volume change rate of 0.5%, conventional lithium battery safety and storage function, and high and low temperature battery performance. Its uses include: equipment troops, aviation, aerospace, deep-sea submersible equipment power supply, polar scientific research, exploration equipment power supply, cold belt rescue, disaster relief power supply, cold clothing, cold shoes power lamp.
