Lithium batteries are lightweight, offer a high energy density, and they’re very safe when treated correctly. For the sake of this answer I’ll compare them to a couple of other common chemistries.

NiMH batteries are pretty robust, but they’re heavier and pack less energy for the weight. They have their applications, but they’re not fit for mobile devices.

Lead acid batteries are also pretty hardy. However, they’re even worse on energy density and weight. They can potentially provide a lot more current than either NiMH or Li-ion, which makes them great for UPSes and car batteries. They also don’t mind being trickle charged, and they’re easy to charge. Just give them the right current and voltage and you’re good to go.

Lithium polymer battery cell:

The raw materials are generally mixed with lithium cobalt oxide, lithium manganate, and ternary lithium. Through a certain proportion of the three mixtures, a certain process is used to make the outer packaging mainly using aluminum plastic film, and the lithium material in the middle is paste. So the shape can be customized. At the same time, you can make ultra-thin batteries, such as ultra-thin batteries such as 0.33mm and 0.50mm.

Lithium polymer battery capacity:

Since the polymer battery can be of any size, it has no standard shape. The general volume is marked as long * wide * thick. In addition, the battery has a positive and negative tolerance, the length and width are 0.5 mm, and the thickness is 0.55 mm. The polymer is determined by the size of the volume, and is also related to the ratio of the lithium raw material.

The outer surface of the polymer battery is made of a layer of aluminum plastic film, and a layer of high-temperature adhesive tape is applied outside. The maximum safety of the polymer is that it leaks, short circuit, and causes the package to rise. The worst case is the burning and the flame. Therefore, compared with the Li-ion battery, the polymer battery is safer.

In the past ten years, with the rapid development of communication technology, mobile phone color screen technology, MMS technology, Bluetooth technology and camera technology have appeared successively, which puts higher requirements on the capacity, volume, weight and electrochemical performance of the battery. Traditional liquid lithium batteries have become increasingly unable to adapt to new demands. The emergence of a new polymer lithium-ion battery (Li-Polymer) caters to this demand. Polymer lithium battery is a third-generation lithium-ion battery developed on the basis of the original steel shell and aluminum shell battery. It is lighter, thinner and has higher energy density. It is accepted by domestic and foreign communication terminal manufacturers and design companies.
