Before we start, let us first define what polymer is. Or should be rather say what polymer does like making bank notes. Chemically speaking, a polymer is ‘a large molecule, or macromolecule with many repeated subunits.’ These flex between each other. Our clothes comprise polymers, and we have lithium polymer batteries.
Latex rubber is also a polymer. So are many of the flexible plastics we use such as pvc and silicone. Whether we would sell as many polymers at tupperware parties is something you can decide. It is time to get back on topic and discuss polymer batteries.
Two Types of Lithium Polymer Batteries
Early polymer batteries used a polymer material as the electrolyte. Scientists hoped to develop a thin, flexible cell in a variety of shapes that would not leak.
Polymer research continues in the hopes of finding a commercially viable solution.
The lithium polymer batteries on sale in shops as LiPo, LIP, and Li-poly have a different design philosophy. They are flexible polymer pouches holding lithium-ion cells. The answer to ‘which is better, lithium polymer or lithium-ion batteries’ could be, ‘neither, it’s the same thing.’
Applications for LiPo, LIP, and Li-poly Batteries
Modern polymer batteries are almost everywhere we go. They come in all kinds of designer shapes and colors. We find them in radio control aircraft, cars, trains, and airsoft paintball guns.
They also power our mobile phones and notebooks, where their low self-discharge rate is an advantage.
They command their own space in personal electronics and wearables, because small size and high density matter most, not price. If you have a power bank, ultra-thin tablet, or portable media player you have lithium polymer battery energy.
Lithium Polymer Batteries and Safety
Any lithium-ion polymer battery may overheat from over-discharging, a hot environment, or short-circuiting. The polymer outer casing can rupture resulting in explosion, fire and injury. The possibilities are extremely small provided we act smart and follow the instructions. The same applies to automobiles, medication and crossing streets.
