Analyze the common sense of lithium battery

Although rechargeable lithium batteries are widely used in modern digital products such as mobile phones and notebook computers, they have high requirements for charging and discharging in use, and the voltage accuracy of charging equipment is required to be within ±1%. Reasonable use methods are very important for improving the service life of lithium batteries. Lithium batteries can be made into different appearances, such as rectangular, cylindrical, flat rectangular and button type, etc. Depending on the material, the voltage of the monomer is also different. The working voltage of lithium cobalt oxide is generally 3.7V, and the charging is the highest. The voltage is 4.2V, while the lithium iron phosphate (hereinafter referred to as ferrophosphorus) positive electrode is 3.2V, and the maximum charging voltage is 3.65V. The final discharge voltage of the lithium cobalt oxide lithium manganese oxide battery is 2.75V~3.0V, and the phosphorus iron is 2.5V. Lithium cobalt oxide type materials as the positive electrode of lithium batteries are difficult to cope with the impact of high current discharge, so they are often used in low-power electrical equipment such as mobile phones and notebooks. Unlike lithium iron phosphate batteries, they can withstand currents of 20C or more. Discharge detection, so it has been the love of power lithium-ion batteries. In the battery manual, the battery factory will give the best use conditions of the battery, such as the maximum discharge current, the proposed depth of discharge, the duration of high current, etc. When selecting the lithium battery model, the operating conditions of the electrical equipment must be considered, and the importance Current range. It is also necessary to strictly monitor the temperature changes during the use of lithium batteries, and promptly activate protection when abnormalities are found, and stop using them to guard against fires or even explosions. . Lithium battery charging basically uses constant current first, then constant voltage current limiting. From the perspective of practical use, are lithium manganese oxide and lithium cobalt oxide batteries very sensitive to voltage errors, so they are only suitable for single use However, the voltage fault tolerance of lithium iron phosphate batteries is clearly improved. Therefore, in environments where battery packs are used in series, such as electric vehicles, lithium iron phosphate batteries are widely used.
