What Is a Li-ion Polymer Battery?
- Li-ion batteries began appearing in the early 1990's. They have the highest energy density of all rechargeable batteries. But due to safety concerns, developers had to incorporate special features into the design to prevent explosion under certain conditions. These concerns, along with market demands for thinner batteries, led scientists to investigate Li-ion polymer technology
The Basic Li-ion Battery:
- A Li-ion battery consists of an anode made of graphite and a cathode made of "lithiated" metal oxide, not actually the metal Li-ion but a chemical mixture containing Li-ion molecules. The anode and cathode are separated by a non-liquid electrolyte, which completes the chemical action necessary to make it work. While in use, ions of Li-iontravel from the anode and return to the cathode, while electrons travel from the cathode to the anode, thus producing the electricity
- The chemical composition of Li-ion batteries carries a potential hazard of severe and life threatening explosion when they are exposed to extreme heat, overcharges, or if the outputs are shorted either by an external connection or a technical failure in the instrument in which they are installed. So Li-ion batteries must incorporate specific safety features to electronically limit or disconnect their output, or include physically features to reduce internal pressure if abused. The polymer battery improves these features.
The Polymer Separator:
- The separator between the anode and the cathode in a Li-ion polymer battery contains a highly porous solid polymer composite such as polyethylene oxide or polyacrylonitrile, which changes to a gel when the electrolyte is added. The cells are sealed in a plastic aluminum laminate which ruptures and vents any gases caused by electrolyte oxidation, and shuts the cell down in the case of overcharge, short circuit or high temperature, significantly reducing the risk of explosion
Size and Shape:
- Since the plates of a Li-ion polymer battery are cut from die cast materials, they can be stacked like a deck of cards and connected in parallel, giving them the advantage of being made in a wide variety of shapes and sizes. The composition of the polymer separator allows the batteries to be made thinner than competitive types, less than four millimeters. The choice to use a Li-ion polymer battery remains mainly with the manufacturers of the equipment that will use them
- Because of the nature of the separator, Li-ion polymer batteries cost more to manufacture. But ability to be made thinner makes them the preferred choice for many applications. So manufacturers of equipment considering using them need to decide if the dimensions of the battery compartment are worth the additional cost. Consumers should be aware of discounted or counterfeit Li-ion batteries, as they may not have the proper safety features to avoid explosion in abusive conditions
- Don't disassemble
- Don't dispose of in fire
- Don't change or charge battery in hazardous location
