1. Raw materials

Raw materials are the general roots of the two different performances. The polymer battery refers to at least one of the three major components of positive electrode, negative electrode or electrolyte. At present, polymer battery polymer materials developed are mainly used for positive and electrolytes. ① In addition to the inorganic compounds of lithium batteries, the positive electrode material of the polymer battery can also use conductive polymer polymers; (Liquid or colloid).

2. Shape

The polymer battery can be thin, any area and arbitrary shape, because its electrolyte can be solid, glue, and not liquid. The lithium battery uses an electrolyte. Essence

3. Security

The current polymers are mostly soft -packed batteries. The aluminum -plastic film is used as a shell. When the inside uses an electrolyte, the liquid is very hot and does not explode. Natural rupture.

4. Core voltage

Because the polymer battery uses polymer materials, it can be made into a multi -layer combination in the battery cell to achieve a high voltage, and the lithium battery battery cell is said to be 3.6V. If you want to reach high voltage in actual use, multiple multiple needs to be multiple. The battery series can be connected together to form an ideal high -voltage work platform.

5. Conductivity

The solid electrolyte ion conductivity of the polymer battery is low. At present, some additives are mainly added to make it a gel electrolyte to improve the conductivity. This only increases ionic conductors, unlike the conductivity of lithium batteries, maintaining a stable value without being affected by the quality of the auxiliary materials.

6. Capacity

The capacity of polymer batteries has not been effectively increased, and it is still reduced compared with the standard capacity of lithium batteries.

7. Manufacturing process

The thinner the polymer battery is, the better the lithium battery, the thicker the lithium battery, the better the production, which makes the lithium battery expand the field more.

8. Price

At present, the price of polymer batteries on the market is generally higher than lithium batteries, which affects the market capacity of the two. The ratio of the former is 1: 9

9V nickel -hydride battery

9V secondary nickel-metal hydride battery (23F6-220): 9V nickel-metal hydride battery is divided into 9V circular batteries and 9V square batteries. There are two forms of composition, as shown in the figure. It can usually be charged more than 500 times, which is long and environmentally friendly than carbon batteries. It is widely used for toys, remote control cars, remote control.
