Lithium Batteries Knowledge

The full name of lithium iron phosphate battery is lithium iron phosphate lithium ion battery. Because its performance is particularly suitable for power applications, the word "power" is added to the name, that is, lithium iron phosphate power battery. And do you all know the charging skills of lithium iron phosphate? The following will introduce you to the charging skills of lithium iron phosphate batteries.

There may be two basic reasons for the expansion of lithium-ion batteries. The first reason is the level of production technology of polymer lithium-ion batteries: the metal electrode coating is not uniform and the processing technology is relatively rough. Another reason may be the problem of overcharging and overdischarging.

Pay attention to fire prevention while using lithium-ion batteries. Many people may become familiar with lithium-ion batteries from their mobile phones. In fact, it is used in many household appliances. There is no doubt that lithium-ion batteries are being used rapidly due to their high efficiency and lightness. However, if the lithium battery is used accidentally, it may catch fire!

A high-rate battery means that the battery can be discharged at a high current. The high-rate charge-discharge performance of a lithium battery is closely related to the migration ability of lithium ions at the electrode, electrolyte and their interface. All factors affecting the migration speed of lithium ions will definitely affect the high rate of the battery Charge and discharge performance.

Cordless vacuum cleaners generally use power lithium-ion batteries, which are composed of several 18650 lithium-ion batteries in series and parallel to form a lithium-ion battery pack. The lithium-ion battery protection board has protection functions such as over-charge, over-discharge, over-current, and short circuit. Give full play to the safety and stability of the power lithium-ion battery pack. It can work continuously for up to 2040 minutes on a single charge.

Lithium batteries are widely used in electric tools, lighting, wind energy storage, electric cars, toys, instrumentation, UPS backup power, communication equipment, medical equipment and special lamps. So what is the price of lithium batteries? How do lithium battery manufacturers in the market price lithium batteries?

KC certification is a national unified certification mark implemented by the Korean National Standards Committee. Lithium batteries are included in the KC certification catalog as a compulsory certification product. At present, the testing of portable secondary lithium battery packs and lithium batteries must be performed by authorized laboratories in South Korea, and cannot be transferred with the CB report of IEC 62133. After the product has passed the evaluation, it will be issued a Confirmation Letter of Declaration valid for 5 years, during which no factory inspection is required.

How many types of Lithium batteries are there? In fact, there are many types, because each battery manufacturer has its own type and specifications, and there are some customized battery specifications. The following introduces the naming of lithium battery model specifications and the meaning of the letters and numbers on the battery, so that everyone has a better understanding of the battery model specifications.

1. Lithium Cell produce process part

2. Materials part

3. Other aspects

There are two reasons for the excessive self-discharge of lithium-ion batteries: physical micro short-circuit and chemical reaction.
