Characteristics and principles of polymer lithium batteries

At present, due to the high manufacturing cost, the state is making high subsidies for electric vehicles. The main reason for the high cost of electric vehicles is that the cost of lithium batteries is too high, and its cost has exceeded one-third of the entire vehicle.
   
  Structural characteristics of polymer lithium-ion batteries
     The electrolyte of polymer ionic battery is to adsorb liquid organic electrolyte on a polymer matrix, called colloidal electrolyte. This electrolyte is neither a free electrolyte nor a solid electrolyte, so it can be made into batteries of any shape and size. For example, it can be made into an extremely thin battery with a thickness of only 1mm. A 12V battery pack can be only 3mm thick.

   The electrolyte is in the positive
     The role of conducting electrons between the negative electrodes is the guarantee for lithium-ion batteries to obtain the advantages of high voltage and high specific energy. Electrolyte is generally prepared from high-purity organic solvents, electrolyte lithium salts, necessary additives and other raw materials under certain conditions and in a certain proportion.
      
The rapid development of lithium-ion batteries will inevitably drive lithium manganese oxide
     The development of related mid-upstream industries such as lithium cobalt oxide and lithium iron phosphate. Of course, in the process of being driven, there is also fierce competition among the raw material production industries of lithium manganate, lithium cobalt oxide and lithium iron phosphate, because the cathode material required by the lithium-ion battery market is not just lithium manganate.
     

   
  The working principle of polymer lithium ion battery
     The positive and negative active materials of polymer lithium ion batteries are similar to those of liquid lithium ion batteries. The negative electrode can be made of polymer conductive materials, polyacetylene, polyaniline or poly-p-phenol, etc., and the positive electrode can be UCoO2, LiMnO,, LiNiO2 And LiMn2 O, etc.
     The safety performance of supercapacitors higher than that of lithium batteries has also been demonstrated in various events in recent years. In the past year, companies such as Boeing, Apple, and Tesla have all been trapped by the safety of lithium batteries, causing frequent incidents. Experts also pointed out that lithium batteries are "difficult to shift in nature" and it is difficult to make up for their safety shortcomings technically
 

   The so-called super capacitor
     It is a new type of energy storage device between traditional capacitors and rechargeable batteries. The basic principle is the same as other types of electric double-layer capacitors, which use the electric double-layer structure composed of activated carbon porous electrodes and electrolyte to obtain super large capacity.
     

Compared to lithium battery
     Supercapacitors have fast charging and discharging speed, high efficiency, long cycle life and high safety. These seem to be the antidote to the current dilemma in the promotion of electric vehicles. While the lithium polymer battery industry is enjoying the chase of stars holding the moon, one of its potential opponents has quietly approached and looked forward to it. It is a super capacitor.
