Lithium Battery Knowledge
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).
Lithium-ion battery separator, in the structure of lithium battery, the separator is one of the key inner components. For the lithium battery series, since the electrolyte is an organic solvent system, a diaphragm material resistant to organic solvents is required, and a high-strength thin-film polyolefin porous film is generally used.
Ternary lithium battery, also known as ternary lithium polymer, refers to a lithium battery with nickel-cobalt manganate or nickel-cobalt aluminate as the positive electrode material. Ternary lithium batteries are widely used in new energy vehicles due to their smaller size, higher capacity density, and low temperature resistance.
Lithium batteries can be divided into primary lithium batteries and secondary lithium batteries. A secondary lithium battery pack refers to a lithium battery composed of several secondary battery packs, which is called a secondary lithium battery pack. A primary battery refers to a battery that cannot be recharged repeatedly, such as the 5th and 7th batteries we commonly use. Secondary batteries refer to batteries that can be recharged repeatedly, such as nickel-metal hydride, nickel-cadmium, lead-acid, and lithium batteries.
The three commonly used batteries for new energy vehicles are NCM batteries, LiFePO4 batteries, and Ni-MH batteries. At present, NCM batteries and LiFePO4 batteries are more common and highly recognized by the public. So, how to distinguish whether the new energy vehicle battery is a NCM battery or LiFePO4 battery? The following is a brief introduction to the method.
With its excellent performance, lithium-ion batteries have become an ideal power source for a new generation of electric bicycles. It is best to charge the lithium battery of an electric bicycle according to the specification, or to calculate the capacity of the lithium battery and the current of the charger. What are the specific precautions for charging an electric bicycle with a lithium battery?
Last year, Xiaomi announced 200W power fast charging technology, and it only takes 8 minutes to fully charge a 4000mAh battery.
LCO batteries are a branch of lithium-ion batteries. In addition, there are lithium manganese oxide batteries, ternary lithium batteries, and lithium iron phosphate batteries. Compared with other types of lithium-ion batteries, LCO batteries are the most capable of charging Battery.
Compared with traditional mobile phones, smart phones are updated faster, with more and more functions such as high-definition large screens, high-pixel cameras, face recognition, etc., and the promotion and application of 4G, coupled with the improvement of people's disposable income, the shipment of smart phones continues to grow.
