    Lithium with you to discuss the safety of polymer batteries

    China Batter polymer battery (Li-polymer, also known as polymer lithium battery): it is also a lithium-ion battery, but compared with the liquid lithium battery (Li-ion) with high energy density, more compact, ultra-thin , Lightweight, and high security and other obvious advantages, is a new type of battery. In shape, lithium polymer battery with ultra-thin features, can be combined with the needs of various products, made into any shape and capacity of the battery. This type of battery can achieve a minimum thickness of up to 0.5mm. Its nominal voltage and Li-ion is also the nominal voltage of 3.7V, no memory effect. Ordinary lithium-ion battery in the overcharge, short circuit and other circumstances occur when the battery may be inside the temperature rise, the cathode material decomposition, anode and electrolyte materials are oxidized and so on, which led to gas expansion and battery pressure increases, when the pressure reaches a certain The extent possible after the explosion. The polymer lithium-ion battery because of the use of colloidal electrolyte, not because of the liquid boiling and produce a lot of gas, thus eliminating the possibility of a violent explosion. At present, most of the domestic polymer battery is only soft package battery, made of aluminum plastic shell, but the electrolyte did not change. This battery can also be thin, its low temperature discharge characteristics better than the polymer battery, and material energy density and liquid lithium batteries, ordinary polymer battery is basically the same, but because the use of aluminum plastic film, so more than ordinary liquid lithium light. Security, when the liquid just boiling when the soft package of aluminum plastic film will naturally drum or rupture, the same will not explode. It should be noted that the new battery is still possible to burn or swell, security is not foolproof.
