Polymer battery safety issue.1.5V rechargeable battery

　　All lithium -ion batteries, in the past, or these years, including polymer lithium -ion batteries, lithium iron phosphate batteries, etc., they are very afraid of short circuit inside the battery, short -circuit of the battery, and overcharge.

　　Because the chemical properties of lithium are very active and easy to burn. When the battery is discharged and charged, the battery will continue to rise inside. , That is, it will rupture, cause leakage, fire, and even explosion.

　　In order to alleviate the risk of lithium -ion batteries, technicians have added ingredients (such as cobalt, manganese, iron, etc.) that can inhibit the active lithium element, but these do not essentially change the danger of lithium -ion batteries in essence.

　　When ordinary lithium -ion batteries occur when over -charging, short circuit, etc., the phenomenon of heating, orthopedic material decomposition, negative electrode and electrolyte materials may occur inside the battery, which will lead to increased gas expansion and increased battery pressure. Explosion may occur after the degree. The polymer lithium -ion battery will not produce a large amount of gases because the liquid is boiling because the liquid is boiled, which will prevent the possibility of severe explosion.

　　Most of the domestic polymer batteries are only soft -packed batteries. The aluminum -plastic film is used as shell, but the electrolyte has not changed. This battery can also be thinner, and its low -temperature discharge characteristics are better than polymer batteries, while material energy density is basically the same as liquid lithium batteries and ordinary polymer batteries. However, because the aluminum plastic film is used light. In terms of safety, when the liquid is just boiling, the aluminum -plastic film with a soft -packed battery will naturally drum or rupture, and it will not explode.

　　It should be noted that the new battery may still be burned or expanded, and the safety is not foolproof.

　　Therefore, when you use various lithium ion batteries, you must pay attention to safety.
