Factors affecting the safety of lithium-ion batteries and how to choose good lithium-ion batteries

Lithium batteries have penetrated into all aspects, and the development of lithium batteries is an inevitable trend. The application and development of lithium batteries are very rapid, with advantages such as high energy density, long service life, and green environmental protection. What are the factors that affect the safety of lithium-ion batteries? How to choose lithium batteries?

Lithium batteries "are a type of battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. Due to the highly reactive chemical properties of lithium metal, its processing, storage, and use require very high environmental standards. Lithium batteries are widely used in energy storage and power sources, especially with the emergence of lithium iron phosphate material batteries, which has promoted the development and application of the lithium battery industry.

Factors affecting the safety of lithium-ion batteries

1. The ambient temperature should not be too high or too low, and it is best to work at normal temperature;

2. Receiving a violent impact or puncture can immediately cause a fire;

3. Excessive discharge significantly reduces the lifespan of lithium batteries;

4. Poor insulation of the circuit leads to water ingress, resulting in short circuits, etc.

When choosing lithium batteries, there are several points to note:

Has the capacity been clearly indicated. Batteries without clearly labeled capacity are likely to use inferior or recycled batteries. Many cheap batteries on the market are made from recycled battery cores. Although they are cheap, they have a short lifespan and unstable quality. Improper use may damage the phone.

▲ Is there a guarantee of standby time. Standby time refers to the continuous usage time from the battery being installed in the phone to the next charge. The batteries sold in the general market cannot guarantee standby time to customers because of the unstable quality of the batteries. Many cheap batteries have short standby time due to the use of poor quality battery cores.

▲ Whether to install a safety protection circuit board. Without a protective circuit board, there is a risk of deformation, leakage, and explosion in lithium batteries. In the vicious competition of price cutting, various companies are seeking lower priced protective circuit boards or simply omitting this device, resulting in the market being filled with lithium batteries with explosive hazards. Consumers cannot distinguish whether there is a protective circuit board from its appearance, so it is best to choose a reputable merchant to purchase.
