What are the important constituent materials of lithium batteries?

Lithium batteries are widely used in our lives. Most people only know the wide range of uses of lithium batteries, but do not necessarily know which materials are required for it. Let’s analyze the positive and negative electrodes of lithium batteries for lithium ion positive and negative electrodes. Material requirements: 1. It has a layered or tunneled crystal structure to facilitate the insertion and extraction of lithium ions. The crystal structure is firm and has good stability within the charge and discharge voltage range, so that the electrode has good charge and discharge reversibility. In order to ensure the cycle life of the lithium battery; 2. During the charging and discharging process, there should be as much lithium ion insertion and extraction as possible, so that the electrode has a higher electrochemical capacity; 4. When the lithium ion is inserted and removed, the electrode reacts The free energy change should be small, so that the battery has a relatively stable charge and discharge voltage to facilitate the wide application of lithium battery packs; 5. Lithium ions should have a large diffusion coefficient to reduce the energy loss caused by polarization and ensure the battery Has good fast charge and discharge performance; 6. Small molecular weight, increase weight energy density; small molar volume, increase volume energy density. LiCoO2 cathode material.
