Guangxin Hongsheng: What is the difference between polymer lithium battery and ordinary lithium battery? How to choose the right one?

With the full popularisation and high-frequency use of smartphones, battery degradation and battery life anxiety have become increasingly concerned pain points. Why not if replacing a battery can give your phone a new lease of life? So what is the difference between the polymer lithium battery, which is a rookie mobile phone battery, and the ordinary lithium battery? How to choose the right between?

First, the battery structure is different

Polymer lithium batteries use polymer as the electrolyte, and the electrodes are composed of a positive electrode coated on conductive aluminium foil and a negative electrode coated on conductive copper foil that are wound with each other, separated by a polymer separator, and finally loaded into a metal shell. Lithium batteries, on the other hand, use an organic liquid as the electrolyte.

Second, security is different

Lithium polymer batteries are safer than lithium batteries, which is determined by the polymer electrolyte used. The polymer electrolyte has better thermal insulation and flame retardancy, and the electrode packaging of the polymer lithium battery is also stronger, and the production process is more stringent, making it easier to achieve fire-free and explosion-free safety performance.

Third, the capacity and weight are different

By changing the ratio of electrode to electrolyte, lithium polymer batteries can achieve higher energy density, so it has a higher capacity at the same volume and is also relatively lightweight. Lithium batteries, on the other hand, are limited by the weight of liquid electrolytes and metal oxide electrodes, and have a relatively low energy density.

Fourth, the cost is slightly different

The production cost of polymer lithium batteries is relatively high, which is determined by its production process and material characteristics. Lithium batteries, on the other hand, are relatively cheap to produce, but their service life and performance are slightly inferior.

In general, polymer lithium batteries have greater advantages than lithium batteries in terms of safety, capacity, weight, etc., but at the same time, the production cost is also higher. Therefore, it is necessary to balance the price/performance ratio in practical applications. If you need higher safety performance and larger capacity and a more relaxed cost budget, then polymer lithium batteries are a better choice. And if you need to control the cost more strictly, lithium batteries are more suitable.

To sum up, although polymer lithium batteries and lithium batteries are both lithium-ion batteries, the difference between them is quite significant. When choosing a battery, you need to combine the application scenario and budget to choose. No matter what kind of battery it is, you need to pay attention to proper use and proper maintenance, so as to be able to give better play to the performance of the battery.
