What is the difference between polymer lithium ion battery and lithium ion battery

This is the overall reason why lithium-ion polymer batteries perform differently than lithium-ion batteries. Polymer battery refers to the use of polymer materials in at least one of the three major components of the positive electrode, negative electrode or electrolyte. In addition to the inorganic compounds of lithium-ion batteries, polymer battery cathode materials can also use conductive high-molecular polymers, and lithium-ion batteries use electrolyte (liquid or colloid). The difference in shaping The polymer battery can be thinner, arbitrarily shaped, and arbitrarily shaped. The reason is that the electrolyte can be solid or colloidal rather than liquid. Lithium-ion batteries use electrolytes and require a solid shell as the second part. The secondary package contains electrolyte. The difference in safety The polymer is mostly a soft pack battery, which uses an aluminum-plastic film as the outer shell. When an organic electrolyte is used inside, it will not explode even if the liquid is hot, but will naturally break. The difference in cell voltage is due to the polymer battery adopts polymer materials, which can be made into a multilayer combination in the cell to achieve high voltage, while the nominal capacity of the lithium ion battery cell is 3.6V, if you want to achieve high voltage in actual use , You need to connect multiple cells in series to form an ideal high-voltage working platform. The difference in conductivity The solid electrolyte ion conductivity of polymer batteries is low. At present, it is important to add some additives to make it a gel electrolyte to improve the conductivity. This is just a new addition of ionic conductivity, unlike the conductivity of lithium-ion batteries to maintain a stable value, and will not be affected by the quality of auxiliary materials.
