Important advantages of lithium-ion batteries.
1.The advantages of lithium-ion batteries are large capacity and high operating voltage. The battery capacity is twice that of an equivalent nickel cadmium battery, making it more suitable for long-term communication. The voltage of traditional
lithium-ion batteries is 3.7V, which is three times that of nickel cadmium batteries and nickel hydrogen batteries.
2. Strong charge retention ability, allowing for a wide operating temperature range. After 30 days of open circuit storage at (20± 5) ℃, the discharge capacity of the battery at room temperature is greater than 85% of the rated capacity. Lithium ion batteries have excellent high and low temperature discharge performance, which can withstand -20 ˉ+ At 60 ℃, the high temperature and discharge performance are higher than other types of cells.
3. Long cycle life. Lithium ion batteries use carbon anodes. During the charging and discharging process, the carbon anode does not exhibit dendrite lithium, thereby preventing internal dendrite lithium short circuits from damaging the battery. After 1200 continuous charges and discharges, the battery capacity is still not less than 60% of the rated value, far higher than other types of batteries, and has long-term economic benefits.
4. High safety, safe and fast charging and discharging. Compared with the metal lithium ion battery, the lithium ion battery has short circuit resistance, resistance overcharge, discharge, shock, vibration, shooting, acupuncture and moxibustion, no fire, no explosion, etc., because its carbon anode has a special electrode to replace the metal lithium electrode, thus allowing rapid charging and discharging, which can greatly improve the safety performance when the 1c charging battery is charged and discharged.
5. There is no environmental pollution. Batteries do not contain harmful substances such as cadmium, lead, and mercury, making them a clean and green source of chemical energy
6. There is no memory effect. It can be reused at any time, especially during wartime and emergency situations.
7. Small size, light weight, and high energy. Generally speaking, the specific energy of lithium-ion batteries is more than twice that of nickel cadmium batteries. Compared with nickel hydrogen batteries of the same capacity, the volume can be reduced by 30% and the weight can be reduced by 50%, which is beneficial for small and lightweight portable electronic devices
Low cost, high performance, high power, high safety, and green environmental protection are the development directions of lithium-ion batteries. As mentioned above, lithium-ion batteries, as a typical representative of a new type of energy, have obvious advantages, but at the same time, there are also some shortcomings that need to be improved.
In recent years, the research and development of active materials and functional electrolytes for the positive and negative electrodes of lithium-ion batteries have been very active internationally, and significant progress has been made. The research on lithium-ion batteries is a constantly evolving battery system. Many new research achievements involving physics and chemistry will have a significant impact on lithium-ion batteries. For example, nano solid electrodes can enable lithium-ion batteries to have higher energy density and power density, greatly expanding the application range of lithium-ion batteries.
