Description

Lithium cell electricity core pole piece breaker

Technical Field

The utility model relates to a lithium cell electric core technical field specifically is a lithium cell electric core pole piece breaker.

Background

After the lithium battery core is overcharged to a voltage higher than 4.2V, side effects can begin to be generated. The higher the overcharge voltage, the higher the danger. When the voltage of the lithium cell is higher than 4.2V, the quantity of lithium atoms left in the anode material is less than half, at the moment, the storage lattice is always collapsed, and the battery generates permanent capacity loss. If charging is continued, since the storage cells of the negative electrode are already filled with lithium atoms, subsequent lithium metal may be deposited on the surface of the negative electrode material. These lithium atoms grow dendrites from the surface of the negative electrode toward lithium ions. These lithium metal crystals may penetrate through the separator to short-circuit the positive and negative electrodes. Sometimes, the battery explodes before the short circuit occurs because the electrolyte and other materials are decomposed to generate gas in the overcharge process, so that the battery shell or the pressure valve is swelled and broken, oxygen enters to react with lithium atoms accumulated on the surface of the negative electrode, and the battery explodes.
