Polymer lithium battery and lithium ion batteries which good? What's the difference?

Source: 2020 - 03 - 25 20:53 hits: polymer lithium battery and lithium ion batteries which good? What's the difference? A list, lithium ion battery is a secondary battery ( Rechargeable battery) , first rely on lithium ion between the positive and negative to work. In the process of discharge, lithium reciprocating inserted between two electrodes and the insert. When charging, lithium from the positive spread out, through the electrolyte embedded negative. State of the cathode is rich in lithium. TV just the opposite. Lithium-ion batteries are widely used in mobile phones and laptop computers, is the representative of modern high-performance batteries. Ii. According to the different electrolytes used in lithium ion battery materials classifying lithium batteries, lithium ion batteries are divided into liquid lithium ion battery ( 自由) , polymer lithium ion battery, PLB) , plastic lithium ion battery ( PLB) 。 This image provided by the registered users' qingfeng-xiangguang fracture xu to, the copyright statement response polymer lithium ion battery materials and the positive and negative of liquid lithium ion is the same. 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. Four, polymer lithium battery and lithium ion batteries which good, polymer lithium battery which good. Polymer lithium battery is an upgraded version of lithium ion batteries. Compared with the current popular lithium ion battery, it has a large capacity, small volume, Thin) And security ( Won't explode) Wait for an advantage. However, due to the whole industry chain of the displacement demand is inevitable, its costs, Money) Still relatively high, in the high-end digital products only use ( Ultrathin laptop computers, etc. ) 。 The major advantages of the polymer lithium battery are as follows: 1. The working voltage of lithium polymer batteries up to 3, 6, 8 v v ~ 3, far higher than that of nickel metal hydride batteries and nickel-cadmium batteries. 2. Polymer lithium battery capacity density is larger, the volume density of nimh battery or nickel cadmium battery 1. 5 ~ 2. 5 times. 3. Small lithium-ion polymer battery self-discharge, placed a long time, little capacity loss. 4, polymer lithium battery life is long, normal use its cycle life can reach more than 500 times. 5, polymer lithium battery has no memory effect, not empty battery before charging, use lunch. 6, polymer lithium battery choose aluminous model on the structure of flexible packaging, different from the metal shell liquid battery, once appear safe hidden trouble, easily burst liquid battery, polymer battery will only at most gas drum. 7, thickness is small, can be made into ultra-thin lithium polymer battery, the battery can be assembled into a credit card. In general, liquid lithium battery using custom shell first, then the positive and negative material blocking method. The thickness of the lithium battery should be under 3 and 6 mm, this is a technical bottleneck. Polymer batteries do not have this problem. 8, lightweight lithium polymer battery choice without metal shell polymer electrolyte battery is a protective packaging. Polymer battery is 40% lighter than steel of the same capacity lithium battery, battery 20% lighter than aluminium. 9, the large capacity polymer lithium battery 10 - higher than the same size standard steel 15% of the battery capacity, higher than 5 - aluminum battery 10%, has become the preferred color screen mobile phones and MMS, now in the market of new color screen and MMS phones are mostly choose polymer battery. 10, small battery internal resistance polymer lithium battery internal resistance is less than the liquid battery, polymer battery internal resistance can do now is lower than domestic Ω 35 m, greatly reducing the battery power consumption, long standby time, can fully meet international standards. The polymer lithium battery support large discharge current, is the ideal choice of the remote control model, the nimh batteries is also the most promising alternatives. 11, shape can be customized manufacturer don't have to be limited to the shape of the standard, can the economy to make the right size. Polymer lithium battery can increase or decrease the thickness of the cells according to customer demand, the development of new cell model, cheap price, mold cycle is short, some can be customized according to the shape of a mobile phone, in order to make full use of the battery shell space, increase the battery capacity.
