Lithium Ion VS Lithium Polymer batteries

A lithium polymer battery refers to a lithium-ion battery in which the solid-state or the gel state is an electrolyte. Generally, an aluminum-plastic composite film is used as a packaging material. There are currently only two real lithium polymer battery brands in the world, one is Japan’s SONY and the other two are China’s ATL and Grepow. Lithium-ion vs lithium polymer battery, which is better?

Lithium-ion vs lithium polymer:

Which one is safer?

A lithium battery generally refers to an aluminum shell battery, the electrolyte is in a liquid state, and the outer packaging material is an aluminum shell, and the lithium polymer battery is safer than the lithium battery. The lithium-polymer battery is an upgraded product of lithium-ion batteries. It is safer (no explosion) than the current popular lithium-ion battery. a liquid casing will be more susceptible to explosions compared to ones with an aluminum casing.

However, due to the time required for the replacement of the entire industry chain, its cost is still relatively high, and it is only used in high-end digital products (ultra-thin notebook computers, UAV, etc.).

The lithium-polymer battery has no leakage problem, and the inside of the battery does not contain a liquid electrolyte, and a colloidal solid is used.

 What’s the difference in shape?

The polymer lithium battery is a new type of battery, it has more miniaturization, ultra-thin, lightweight, as well as high safety and low cost and other obvious advantages. In shape, the lithium polymer battery has the ultrathin characteristic, may cooperate with each kind of product need, makes any shape and the capacity battery. Grepow’s lithium polymer batteries can be as thin as 0.45mm and a 170-degree bend.

if it is 3.6V 400mAh capacity, Grepow Can make a thin battery for you. Lithium polymer batteries can be designed in a variety of shapes. If you are looking to buy a lithium polymer battery from a manufacturer, you can easily request the size and special shape battery to suit your situation.

Batteries can be bending deformation, polymer battery maximum bending around 90 °.

What’s the difference in voltage?

Lithium polymer battery can be made into a single high voltage cell: liquid electrolyte battery can only be a few batteries in series to get high voltage. and polymer battery itself because there is no liquid, can be made in a single multi-layer combination to achieve high voltage.

 What’s the difference incapacity?

A lithium-polymer battery has a high energy density and can hold twice as much energy as a lithium-ion battery of the same size.

It is foreseeable that in the next 5-10 years, polymer lithium batteries will replace the existing lithium-ion batteries! In fact, the penetration rate of lithium polymer batteries in countries such as Japan and South Korea, which are relatively developed in the electronics industry, has reached a certain level, but China is still relatively backward in this respect. Grepow lithium polymer battery production technology has matured, the market is growing, and the popularity of lithium polymer in China is just around the corner!
