Introduction to the key advantages of lithium batteries

1. The advantages of lithium batteries are large capacity and high working voltage at present. The capacity is twice that of the same nickel-cadmium battery, which is more suitable for long-term communication. The voltage of the usual single lithium battery is 3.7V, which is 3 times that of the nickel-cadmium and nickel-hydrogen batteries. 2. Strong charge retention capability and wide allowable working temperature range. After being stored in an open circuit for 30 days at (20±5)℃, the discharge capacity of the battery at room temperature is greater than 85% of the rated capacity. Lithium battery has excellent high and low temperature discharge performance, can work at -20ˉ+60℃, high temperature discharge performance is higher than other types of batteries. 3. Long cycle life. The lithium battery uses a carbon anode. During the charging and discharging process, the carbon anode will not generate dendritic lithium, so that the battery can be warned of damage due to the internal dendritic lithium short circuit. After continuing to charge and discharge for 1200 times, the battery capacity will still not be less than 60% of the rated value, which is much higher than other types of batteries, which is economical for long-term use. 4. High safety, safe and fast charge and discharge. Compared with lithium metal batteries, lithium batteries have the characteristics of short-circuit resistance, overcharge, overdischarge, shock resistance, vibration resistance, gunshot, needle stick, no fire, and no explosion. Because the anode uses a special carbon electrode to replace the metal lithium battery Therefore, it allows fast charging and discharging, and can be charged and discharged under the condition of 1C charging rate, so the safety performance is greatly improved. 5. No environmental pollution. The battery does not contain harmful substances such as cadmium, lead, mercury, and is a clean green chemical energy. 6. No memory effect. It can be charged and discharged repeatedly at any time, especially in wartime and emergency situations, showing its excellent performance. 7. Small size, light weight and high specific energy. Generally, the specific energy of a lithium battery can reach more than 2 times that of a nickel-cadmium battery. Compared with a nickel-hydrogen battery of the same capacity, the volume can be reduced by 30% and the weight can be reduced by 50%, which is conducive to the small and lightweight portable electronic equipment.
