These lithium atoms grow dendritic crystals in the direction of lithium ions from the surface of the cathode. These lithium metal crystals pass through the diaphragm paper to short-circuit the positive and negative poles. Sometimes in the short circuit before the battery exploded, this is because in the overcharge process, electrolyte and other materials will be cracked to produce gas, so that the battery shell or pressure valve drum burst, so that oxygen into the negative surface with the accumulation of lithium atom reaction, and then exploded.Many companies have begun to use nano-titanium oxide and nano-silicon oxide in the previous traditional graphite, tin oxides, carbon nanotubes inside, greatly improve the lithium battery charge and discharge and the number of times.
