 What is a fast charge battery?

Most of the fast-charging batteries on the market are lithium-ion batteries, so the fast charging generally refers to lithium-ion batteries. The charge-discharge rate of a lithium-ion battery determines how fast we can store a certain amount of energy in the battery, or how fast we can release the energy in the battery.

When charging, lithium ions are generated on the positive electrode of the battery, and the generated lithium ions move to the negative electrode through the electrolyte. The carbon as the negative electrode has a layered structure, which has many micropores for the insertion of lithium ions that reach the negative electrode.

The more lithium ions are inserted, the higher the charging capacity. During fast charging, lithium ions need to be quickly inserted into the negative electrode. This poses a great challenge to the negative electrode's ability to quickly receive lithium ions. The battery of ordinary chemical system will have by-products in the negative electrode during fast charging, which will affect the cycle and stability of the battery. The core of the lithium battery fast charging technology is to accelerate the speed of lithium ions moving between the positive and negative electrodes through chemical system and design optimization without affecting the battery life and reliability.

Is there any difference between fast charge battery and ordinary battery?

Fast-charge battery refers to a battery that can be fully charged with 80% or 100% power in a short period of time. By changing the electrolyte formula of the battery itself, it can withstand a larger current and be fully charged in a short time. This is the biggest feature of fast charging batteries. Fast-charge batteries can be divided into lithium-ion batteries, button batteries, nickel-metal hydride, nickel-cadmium batteries, etc. according to their materials. The following are the differences between quick-charge batteries and ordinary batteries.

1. Extremely fast charging. For example, charge more than 80% of electricity in 15 minutes;

2. Ultra-long and durable: After 500 times of fast charging, it still maintains more than 80% of the capacity;

3. Safe and reliable: Comply with lithium battery safety standards such as IEC, UL, PSE, UN38.3, etc.;

4. Wide application: It can be customized and developed according to actual needs, and it is widely used in consumer electronics, toys and other electronic products.
