What are the precautions for lithium-ion polymer battery to use?

Source: 2020 - 03 - 24 therefore hits: lithium-ion polymer battery application note is what? Electrolyte material for lithium-ion batteries, according to the use of different, divided into liquid lithium ion battery ( 自由) And polymer lithium ion battery, PLB) 。 The positive and negative materials used in the polymer lithium ion battery is the same as the liquid lithium ion. The anode material into lithium cobalt oxide, lithium manganese oxide, ternary material and lithium iron phosphate material. The first difference is the electrolyte. Liquid lithium ion battery using the liquid electrolyte, polymer lithium ion battery using the solid polymer electrolyte, it can be either 'dry', can also be a 'colloid. 1 classification solid lithium ion battery electrolyte is a mixture of a polymer and salt. The battery low room temperature ionic conductivity, can be used at room temperature. Gel lithium ion battery is in solid polymer electrolyte adding plasticizer and other additives, then positive ion conductive and make a battery can be used at room temperature. Polymer conductive polymers as lithium ion battery cathode material, improve the specific capacity of lithium ion batteries. Compared with liquid lithium ion batteries, polymer lithium ion battery has a small thickness, area is large, shape arbitrarily, etc. Battery shell, therefore, can use aluminum-plastic composite membrane, increase the specific capacity of the battery. Polymer polymer lithium ion battery can also be used as the anode material, its quality - Energy than would be more than 20% more than the liquid lithium ion battery. Polymer lithium ion battery has small volume, light weight, small thickness, etc. Therefore, polymer battery increasingly appear on the market. 1. Note polymer lithium ion battery short circuit conditions, in the process of charging is very short short circuit. Including: internal short circuit and external short circuit, and so on and so forth. Although now most of the lithium ion battery with blast proof and short circuit protection circuit and the line, but in many cases, the protection circuit is not necessarily effective in all situations, the effect of explosion-proof line is limited. Don't overcharge polymer lithium ion battery, assumes that the charging time is too long, will increase the likelihood of burst. Lithium chemical nature very lively, very short, battery charge and discharge, battery continues to heat up, activation process against gas expansion, increased cell pressure, a certain amount of stress, such as the shell of the scar, it will break, cause leakage, fire, or even an explosion. Polymer lithium ion battery will only expand. We must pay attention to safety when used. At present there are two types: lithium ion battery liquid lithium ion battery, 自由) And polymer lithium ion battery, PLB) 。 At the same time, the liquid lithium ion battery to embed the lithium ion compounds known as the positive and negative secondary battery. Is extremely or LiCoO2, LiNiO2, LiMn2O4 lithium compounds, carbon negative extremely lithium compound LixC6 between the layers. A typical battery system are as follows: ( - ) C | LiPF6EC+DEC | LiCoO2( +) Polymer lithium-ion batteries, polymer lithium ion battery ( 15) The positive reaction ( Oxidation reaction) :LiCoO2 = li1 - Xcoo2 + xLi++ xe negative reaction ( Recycling response) :6C+xLi++xe- =LixC6( 2. 2) Total cell reaction: LiCoO2 + 6 = li1 - c xcoo2 +LixC6( 2. 3) Polymer lithium ion battery works the same as the liquid lithium, the main difference lies in the electrolyte is different from liquid lithium. The basic structure of the battery is made up of three parts: the anode, cathode and electrolyte. Polymer lithium ion battery refers to the least in three basic structures of one or more polymer materials as the main battery system. In polymer lithium ion battery systems, polymer material is mainly used in the anode and electrolyte. Anode materials containing conductive polymer or inorganic compounds are generally selected, lithium ion battery electrolyte can use solid or gel polymer electrolyte, or organic electrolyte, general use liquid or gel electrolyte lithium ion technology, so demand stable secondary packaging to the flammable, active ingredients, this increases the weight, in addition to the flexibility of constraint specifications.
