In the winter, the cruising range of electric vehicles is much less than that indicated by the manufacturer, and some even reach more than one-third. Why is this? This starts with the principle of electric vehicle batteries. When electric vehicles are parked outdoors in winter, the low temperature will directly affect the activity of lithium batteries, and restoring battery activity requires electricity to heat the battery to restore the temperature, and this part of the consumed electricity is the “shrinking” part of the battery life. Generally speaking, the vast majority of electric vehicles and even electronic digital products on the market currently use lithium-ion batteries, which are often referred to as lithium batteries. Common electric vehicle lithium batteries are mainly lithium iron phosphate, lithium manganate and ternary lithium batteries . Like common batteries, lithium batteries are also divided into positive and negative poles, in which all lithium ions

Lithium battery separator is one of the key inner layer components of lithium battery. The performance of the separator determines the interface structure and internal resistance of the battery, which directly affects the capacity, cycle and safety performance of the battery. The separator with excellent performance plays an important role in improving the overall performance of the battery. First, Characteristics of lithium battery separator The main performance requirements of lithium-ion battery separators are: thickness uniformity, mechanical properties (including tensile strength and puncture resistance), air permeability, physical and chemical properties (including wettability, chemical stability, thermal stability, safety), etc. Four performance indicators. Second, the performance of lithium battery separator The lithium battery separator is located between the positive electrode and the negative electrode, and its main function is to separate the positive and neg

The liquid lithium battery is mainly composed of four major parts: positive electrode material, negative electrode material, diaphragm, and electrolyte. The electrolyte is mainly responsible for conducting conductive ions between the positive and negative electrodes, which affects the energy density, cycle life, power density, and safety performance of the battery. , wide temperature applications, etc. will play a key role, known as the "blood of the battery". In the application of batteries, the electrolyte needs to meet the performance indicators such as high electrical conductivity, good thermal stability, high chemical stability, wide electrochemical window, wide operating temperature range, and good safety. So, what are the main components of the lithium battery electrolyte? The main components of the lithium battery electrolyte are raw materials such as solvents, solutes and additives, which are prepared in proportion and under certain conditions. The q

Ternary lithium battery (ternary polymer lithium ion battery) refers to a lithium battery in which the positive electrode material of the battery uses nickel cobalt lithium manganate or nickel cobalt lithium aluminate ternary battery positive electrode material. The ternary composite positive electrode material is a nickel salt , cobalt salt, manganese salt as raw materials, the proportion of nickel, cobalt and manganese in it can be adjusted according to specific needs, ternary materials are mainly used for new energy vehicles, electric vehicles, pneumatic tools, energy storage, intelligent intelligent sweepers, drones , intelligent smart wearable devices and other fields. The best charging range of ternary lithium battery The best charging range of ternary lithium battery is 20%-80%. When the battery power drops to close to 20%, it should be charged in time, which is beneficial to prolong the service life of the battery. At the same time, if there is no special require

Ternary lithium-ion batteries have excellent electrochemical properties such as high energy density, good safety and stability, support for high-rate discharge, and moderate cost advantages. The battery field has been widely used. Ternary material lithium-ion batteries are generally divided into ternary polymer lithium-ion batteries, ternary power lithium-ion batteries, and ternary low-temperature lithium-ion batteries . 1. Ternary polymer lithium-ion battery Ternary polymer lithium ion battery refers to a lithium ion battery whose positive electrode material uses nickel cobalt lithium manganate ternary positive electrode material and uses gel polymer electrolyte. As a transport medium for ion movement, electrolyte is generally composed of solvent and lithium salt. The electrolyte of lithium secondary battery mainly includes liquid electrolyte, ionic liquid electrolyte, solid polymer electrolyte and gel polymer electrolyte. Its greatest advantage is the high mechanical
