All lithium ion batteries, whether in the past or in recent years, including lithium polymer batteries, lithium iron phosphate batteries and so on, are very afraid of internal battery short circuit, external battery short circuit, overcharge these situations.
Lithium polymer battery uses file alloy as positive electrode, polymer conductive material, polyacetylene, polyaniline or polyphenol as negative electrode, organic solvent as electrolyte. The specific energy of lithium polyaniline battery can reach 350w.h /kg, but the specific power is only 50-60W/kg, the service temperature is -40-70 degrees, and the service life is about 330 times.
Compare the battery capacity. General cadmium nickel battery is 500mAh or 600mAh, nickel hydrogen battery is 800-900mah; The capacity of lithium-ion mobile phone battery is generally between 1300-1400mah, so the time of lithium battery after full charge is about 1.5 times that of nickel hydrogen battery, and about 3.0 times that of cadmium nickel battery. If it is found that the lithium ion mobile phone battery you buy does not work as long as advertised or specified in the manual, it may be counterfeit.
In the retired lithium iron phosphate batteries, the batteries that do not have the value of step utilization and the batteries after step utilization will eventually be dismantled and recycled. The difference between lithium iron phosphate battery and ternary material battery is that it does not contain heavy metals, and the recovery is mainly Li, P and Fe. The added value of the recovery product is low, so a low-cost recovery route needs to be developed. There are two main methods of recovery: fire method and wet method.
