The battery is the main power source of the product. It can drive the operation of the equipment. Using test tools to conduct detailed inspections on the battery can ensure the safety of the battery and prevent the battery from spontaneous combustion and explosion due to excessive temperature.

Special lithium batteries refer to a special type of lithium battery technology, which are different from traditional lithium-ion batteries (Li-ion) in terms of electrochemical performance, structural design, and material composition. Compared with civilian lithium-ion batteries, special lithium-ion batteries usually have the characteristics of high energy density, high power output, long cycle life, high safety and stability.

The 18650 lithium battery is a type of lithium-ion battery and a pioneer of lithium-ion batteries. There are many situations where the 18650 battery cannot be charged, and it is necessary to take corresponding repair methods to effectively solve the problem that the 18650 battery cannot be charged. So what are the reasons and solutions for the battery not charging?

Sodium batteries are batteries that use sodium ions as charge carriers. Batteries charge and discharge by inserting and separating sodium ions between positive and negative electrodes. Sodium batteries work on basically the same principle as lithium batteries, except for a different charge carrier.

Low-temperature lithium-ion battery is a new type of lithium-ion battery, its main feature is that it can work normally at a lower temperature (usually -10°C to -50°C), suitable for power in cold regions or low temperature environments storage and use.

Lithium batteries in laptops have no memory effect, and lithium batteries produced by regular manufacturers have a fairly complete BMS (battery management system) to control overcharging and overdischarging problems.

Lithium battery pack refers to the assembly and production of lithium batteries, also known as lithium battery pack. Pack refers to the customized packaging, encapsulation, and assembly of lithium batteries. The main process is divided into three parts: processing, assembly, and packaging. When several modules are jointly controlled or managed by the BMS and the thermal management system, the unified whole is called a lithium battery pack.

An electrolyte is a compound that can conduct electricity when dissolved in an aqueous solution or in a molten state, and can dissociate into freely moving ions when dissolved in water or heated. The electrolyte is an important part of the lithium-ion battery, which plays the role of transporting ions and conducting current between the positive and negative electrodes.

Lithium batteries can be roughly divided into two types: lithium metal batteries and lithium ion batteries. Lithium metal battery is a battery that uses metal lithium as the negative electrode, and the matching positive electrode material can be oxygen, elemental sulfur, metal oxide and other substances; lithium ion battery does not contain metallic lithium and is rechargeable.

Li-ion battery charging in low temperature environment has certain risks. Because with the decrease of temperature, the dynamic characteristics of graphite anode become worse and worse. During the charging process, the electrochemical polarization of the anode is significantly intensified. The precipitated metal lithium is easy to form lithium dendrites, break through the diaphragm and cause the positive and negative pole short circuit. Try to prevent lithium ion batteries from charging at low temperature.
