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.

The full name of the ternary lithium-ion battery is the ternary polymer lithium battery. The ternary polymer lithium battery refers to the lithium battery whose positive electrode material uses nickel-cobalt lithium manganate (Li(NiCoMn)O2) ternary positive electrode material. The ternary composite positive electrode material Precursor products are made of nickel salt, cobalt salt, and manganese salt. The ratio of nickel, cobalt, and manganese can be adjusted according to actual needs. The battery with ternary materials as the positive electrode is safer than lithium cobalt oxide batteries.

The number of kilometers that a lithium battery electric vehicle can run on a full charge is mainly related to the capacity of the lithium battery configured, and also has something to do with the method of use and the quality of the lithium battery. Let's learn more about the lithium battery charging instructions, maintenance and use precautions of lithium electric vehicles!

The performance of the lithium-ion battery cathode material directly affects the performance of the lithium-ion battery, and its cost also directly determines the cost of the battery. At present, the positive electrode materials that have been successfully developed and applied mainly include lithium cobalt oxide, lithium iron phosphate, lithium manganate, ternary materials nickel cobalt lithium manganate (NCM) and nickel cobalt lithium aluminate (NCA).
