What is the difference between polymer lithium batteries and lithium iron phosphate batteries?

Lithium polymer battery (Li - polymer) is on the basis of the lithium ion battery with polymer electrolyte to replace the traditional organic liquid electrolyte. The polymer electrolyte that can be used as the transmission medium of ions, and can be used as isolation membrane, and the reactivity of metallic lithium is extremely low, thus effectively avoid the lithium ion battery of easy combustion and leakage phenomenon.

And because the lithium-ion polymer battery is the organic liquid electrolyte adsorption on a polymer matrix, called the colloidal electrolyte, the electrolyte is neither free nor solid electrolyte, electrolyte so as to make the son of lithium polymer battery not only has excellent performance of liquid lithium ion battery, also can be made into any shape and size, ultra-thin products, make its applicability is wide and good prospects for development. Additional security is better than lithium ion battery, use of if fever, will only produce bloat or without burning explosion.

lithium iron phosphate battery refers to lithium ion battery with lithium iron phosphate as the positive electrode material. Long life lead-acid battery cycle life of about 300 times, the highest is 500 times lithium iron phosphate battery, and lithium iron phosphate power battery, cycle life reach more than 2000 times, standard charge (5 hours rate) use, can reach 2000 times. Lead-acid battery of the same quality is "new half year, old half year, and maintenance of half a year", the most is 1~1.5 years, and lithium iron phosphate battery in the same condition, will reach 7~8 years. Taken together, the performance price will be more than four times that of lead-acid battery.

In addition, the polymer lithium battery (3.7v) is light in weight and higher in voltage than lithium iron phosphate (3.2v). The high temperature resistance coefficient is lower than that of lithium iron phosphate.
