How to measure the quality of lithium-ion battery cathode materials? I believe that everyone is not very familiar with it. Let's follow the new energy manufacturers of Tuopai to find out.
(1) The positive electrode material should have a high redox potential, so that the battery has a high output voltage
(2) Lithium ions can be reversibly intercalated and deintercalated into a large number of cathode materials, enabling batteries with high capacity
(3) During the lithium ion intercalation and delamination process, the structure of the cathode material should not be changed or changed as little as possible to ensure good cycle performance of the battery
(4) During the insertion and de-insertion of lithium ions, the redox potential of the positive electrode should be changed as little as possible, so that the voltage of the battery will not change significantly, in order to ensure the smooth charging and discharging of the battery.
(5) The positive electrode material should have high conductivity, so that the battery can be charged and discharged with a large current
(6) The positive electrode does not react with the electrolyte
(7) Lithium ions should have a large diffusion coefficient in the electrode material,
(8) The price is cheap and does not pollute the environment.
