How to improve the energy density of lithium batteries

Source: 2020 - 04 - 04 now hits: time how to improve the energy density of lithium-ion batteries 1. To improve the anode material than the storage capacity ( G storage capacity) In the positive active material possession there is a cap. In the total number of the positive active material must be case, only the largest number of lithium was isolated from the positive ions thermal chemical reaction, to improve the energy density. Therefore, removable lithium ion is higher than the quality of the products share the positive active material, the quality of the products share the positive active material is higher than the quality of the products share storage index. 2. Improve anode materials than the storage capacity of the anode materials is often the case, not power lithium battery energy storage density of a major breakthrough, but if further improve cathode than store, on behalf of the quality of the product less, lithium ion anode materials can accommodate more and more, to improve the energy density increased. 3. To improve the occupancy rate continuously increase the positive active material of the positive active material in the share of main purpose is to increase the share of lithium continuously. In the same cell mechanism in the chemical industry, the composition of lithium ( Other necessary conditions for the same) , the energy density increased accordingly. So under the limit of certain volume and total weight, do you want to have a more positive active material, a little more. 4. Constantly improve the proportion of active substances in the cathode design is in order to better match the positive active material, and a growing number of negative active material for lithium ion downstream, to store the kinetic energy. If there is not enough in the cathode active material, will spare lithium ion precipitation and accumulation on the surface of the cathode, rather than get inside the cathode. Irreversible thermal chemical reaction and battery capacity attenuation coefficient often occur.
