Description

Technical field: [0001] The present invention mainly relates to a formula and method of a patch coating material used for rechargeable batteries, which is suitable for rechargeable lithium batteries or nickel-hydrogen batteries. Background technique: [0002] With the rapid development of modern electronic technology, rechargeable batteries are used in large quantities, such as lithium batteries. When they are charged, they generate lithium ions under the action of external voltage, which accumulate at the electrodes, and they become lithium atoms when they are discharged; this repeated movement, The rechargeable battery can be used many times and has a longer service life. Due to the flow of ion current in the battery, some variant substances are produced at the battery electrodes. With the increase in the use of rechargeable batteries, these substances gradually increase, which hinders the full production of lithium ions and the smooth flow of lithium ions. As a result, the per...
