There are many advantages of the lithium battery.
The advantages of the lithium ion battery are that the capacity is large and the operating voltage is high. The capacity is twice of the same nickel-cadmium battery, and it is more suitable for long-term communication. The voltage of a typical single-cell lithium battery is 3.7V, which is three times that of nickel-cadmium and nickel-hydrogen batteries.
The second, the charge retention ability is strong, allowing a wide operating temperature range. At (20 ± 5) ° C, after 30 days of storage in an open circuit, the normal temperature discharge capacity of the battery is greater than 85% of the rated capacity. Lithium-ion battery has excellent high and low temperature discharge performance, can work at -20 ˉ +60 ° C, high temperature discharge performance is higher than other types of batteries, especially lithium iron phosphate solar street lamp lithium battery pack can better support high temperature.
Third, the cycle has a long service life, and the lithium ion battery uses a carbon anode. During the charging and discharging process, the carbon anode does not generate dendritic lithium, thereby preventing the battery from being damaged due to internal dendrite lithium short circuit. After 1200 consecutive charge and discharge, the battery capacity is still not lower than 60% of the rated value, much higher than other types of batteries, and has long-term economical use.
Fourth, high security, safe and fast charge and discharge. Compared with metal lithium batteries, lithium-ion batteries are resistant to short circuits, overcharge, over discharge, shock, vibration, gunshot, acupuncture, no fire, no explosion, etc., because the anode uses a special carbon electrode instead of metal. The lithium electrode allows rapid charging and discharging, and can be charged and discharged at a charging rate of 1 C, so the safety performance is greatly improved.
Fifth, No environmental pollution. The battery does not contain harmful substances such as cadmium, lead and mercury. It is a clean "green" chemical energy source.
6, No memory effect. It can be used repeatedly at any time, especially in wartime and emergency situations.
Seventh, small size, light weight, high specific energy. Generally, the specific energy of a lithium-ion battery can be more than twice 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 advantageous for small and lightweight portable electronic devices.
