The biggest safety difference between Li-Polymer and Li-Ion batteries is that Li-Ion batteries explode when both cells are heated to a certain degree, while Li-Polymer batteries
only have chemistry. Volatile, at most flammable, but never exploded.
Polymer lithium batteries, also known as polymer lithium batteries
, are chemical batteries. Compared with previous batteries, it features high energy, miniaturization and light weight. Lithium polymer batteries have ultra-thin characteristics, and can be made into batteries of various shapes and capacities to meet the needs of certain products. The theoretical minimum thickness can reach 0.5mm. Polymer lithium batteries use file alloys as positive electrodes, polymer conductive materials, polyacetylene, polyaniline or poly-p-phenol as negative electrodes, and organic solvents as electrolytes. The specific energy of polyaniline lithium battery can reach 350W.h/kg, but the specific power is only 50-60W/kg, the working temperature is -40-70 degrees, and the service life is about 330 times.
The polymer lithium battery
is a kind of battery with high working voltage, small size, light weight, high energy density, no memory effect, low pollution, low self-discharge and long cycle life. It has been widely recognized due to its many advantages. Since commercialization, lithium-ion batteries have been conquering cities and have been widely used in portable appliances such as laptop computers, video cameras and mobile communications.
