Types and differences of lithium batteries

Types and differences of lithium batteries 1. Classification according to battery positive and negative materials. 1. Lithium cobalt oxide battery: its high specific energy can make lithium cobalt oxide battery into mobile phone. Due to the excellent chemical molecular formula of lithium cobalt oxide batteries, the structure of rechargeable batteries is stable, the volume is relatively high, and the comprehensive type can be prominent, but its safety factor is poor, and the cost is also high. The key is to use large, medium and small lithium batteries, which are widely used in Small notebooks, smart phones, MP3/4, notebook computers, digital cameras and other small and medium-sized electronic products, the product characteristics are particularly stable, the maximum battery charging power working voltage is normal from beginning to the end, the comprehensive type can be highlighted, the standard working voltage is normal, 2. Manganese acid Lithium battery: Lithium manganate battery can be charged and discharged with a current of 20-30A, and has a suitable standard for hotness. Although low cost, high safety factor, and good ultra-low temperature characteristics, the raw material itself is not stable and easily dissolves to cause vapor. Therefore, it is mostly used to mix with other raw materials to reduce the cost of lithium batteries, but its cycle time service life attenuation coefficient is relatively low. Fast, prone to swelling, weak high-temperature characteristics, and short service life. The key is small lithium batteries and power lithium batteries. The nominal voltage is the working voltage. Lithium manganese battery spare parts for pneumatic tools, medical equipment, hybrid vehicles and new energy vehicles. 3. Lithium iron phosphate battery: Lithium iron phosphate battery has excellent safety, photoelectric catalytic characteristics and small resistors. The relative density of power energy is high. If the processing manufacturer has good winding processing technology, the processing capacity can be larger, which can achieve 185 watts/kg. The safety factor is excellent. During the entire process of battery charging, the structure of the internal rechargeable battery is not prone to major changes, nor will there be a strong explosion, even if there are accidents such as short-circuit failure, overcharging, and collision. Very safe. 2. According to the general classification of the internal structure raw material lithium battery. 1. Lithium metal batteries: Lithium metal batteries generally use manganese dioxide as the battery cathode material, metal lithium or its alloy steel metal as the battery anode material, and the battery uses a non-aqueous electrolyte reaction solution. 2. Lithium batteries: Lithium batteries generally use lithium alloy steel metal oxides as battery cathode materials, high-purity graphite as battery anode materials, and rechargeable batteries with non-aqueous electrolytes. 3. Carry out classification according to shell raw materials. 1. One is a battery with a steel case, in short, a steel case. Most processing manufacturers choose steel as the raw material for rechargeable battery casings, because the physical reliability and compressive capacity of steel raw materials are much higher than that of aluminum shell materials. After the reliability design and construction of various processing manufacturers, the safety device has been installed Coming to the lithium battery core, the safety factor of the aluminum shell column-type rechargeable battery has achieved a new aspect ratio. 2. Another type, aluminum shell rechargeable battery, the same reason, the shell is made of aluminum material. Aluminum shell rechargeable batteries are a shell type and a soft shell type. There are many kinds of battery cathode materials. Depending on which one you like to use, the areas where different raw materials are used are still different. 3. Polymer lithium battery, the casing is made of polymer raw materials, most of which are silver, and a few of them are dark gray, which are called black skins in the category. It is mainly used for car electronic equipment (GPS positioning tracking rechargeable battery, tire pressure inspection rechargeable battery, driving recorder rechargeable battery, shared bicycle, solar power energy storage technology light, low temperature wireless walkie-talkie, etc..
