What is the inside of the gas after bulge lithium-ion batteries?

Source: 2020 - 03 - 29 sets of hits: first lithium battery expansion after the gas inside, poisonous? Treasure is the affirmation of the lithium ion battery, charging collisions produce all sorts of side effects, a gas such as hydrogen, carbon monoxide, carbon dioxide and various kinds of alkanes main body smell is the evaporation of electrolyte is not wrong, ethylene carbonate, dimethyl carbonate, etc. , toxicity is not big, but smell occasionally there will be no problem! ! You can't use this battery! ! Throw it away! ! Lithium ion battery is in the case of no water and no oxygen work required ( So it is necessary to seal the aluminum plastic film or stainless steel shell) , if you have any oxygen into water, I don't know what a chemical reaction, is not impossible. Be careful not lead-acid batteries, lithium ion batteries metal hydride batteries, zinc manganese battery, etc. These cells are made from electrolysis of water, and sometimes the trick is to saline injection of the zinc manganese dry cell death, and still use it, I don't know whether it is effective, but at least it doesn't have any security problems; If you put water in the lithium ion battery science pay lithium ion battery is reaction of the chemicals in the process of charging and discharging, lithium ion run between the positive and negative, may consume electrolyte. The positive data is commonly graphite of the lithium ion battery, the positive data is commonly lithium cobalt oxide, lithium iron phosphate, nickel and cobalt manganese three metadata. The commonly used electrolyte for organic solvent ( Ether) Six fluoride phosphate, lithium solute. Generally the use of special processing of polyethylene, polypropylene and its composite materials for clearance, which is separated from the cathode, the micro hole on the clearance can be through the electrolyte. Lithium iron phosphate batteries, refers to the lithium iron phosphate battery with the positive. T cells, refers to the three source data with the anode nickel cobalt manganese battery. Lithium titanate battery, refers to the lithium titanate battery with the cathode. 18650 cell is a specific standard stainless steel shell cell ( Cylindrical, 18 mm in diameter, the length of 65 mm) 。 Soft package battery, refers to the battery packed in aluminum composite membrane. Polymer lithium ion battery, it is to point to not polyethylene polypropylene split, electrolyte solution phase, and used as a polymer gel electrolyte of lithium ion battery ( By polymer gel so naturally from the cathode is cut off, and the gap effect) , during which the gel electrolyte solute still six lithium fluoride phosphate, gel contains also contains ether solvents. In short, polymer lithium ion battery is still essentially lithium ion batteries. 18650 batteries and soft bag packing way, just not sure exactly what kind of batteries.
