Dotted Coated POM Material Technology Research Advancement

摘要

1. Dotted coated technology can improve LCO high voltage stability refer to XRD and Co solution content analysis 2. Dotted coated technology can improve LCO high temperature storage performance 3. Dotted coated technology can improve LCO battery safety performance, such as crush, penetration, overcharge and so on in some content 4. Dotted coated technology would cause the LCO low temperature discharge performance a little worse 5. Dotted coated technology can improve Graphite rate discharge and low discharge performance, cycle life performance keep the same 6. Dotted coated technology can improve Graphite safety performance, especially low temperature charge/heating test, penetration, etc. 1. POM cathode material is chemical synthesis method, process is simple, no need high temperature, so the cost is lower 2. POM cathode molecular cluster ion is stable, decomposition temperature is much higher compared with traditional cathode material, safety performance is good 3. POM cathode energy density higher 4. POM conductivity is not good, need improve the conductivity with physical conductive agent mixing and conductive polymer coating 5. POM cathode need use rich Li material be the anode, like Li metal.
