Lithium battery has high power bearing capacity, in which lithium ferrous phosphate lithium-ion battery for electric vehicle can reach 15-30c charge and discharge capacity, which is convenient for high-intensity start-up and acceleration. The rated current of lithium battery is high (the single working standard voltage is 3.7V or 3.2V), which is equal to the series voltage of three nickel cadmium or nickel hydrogen rechargeable batteries, so as to form a battery switching power pack; Lithium battery can adjust the working voltage to 3.0V according to the technical characteristics of a new lithium battery AC voltage regulator, so as to be suitable for the application of small household appliances.
The weight of lithium battery is light, and the net weight under the same volume is about 1 / 6-1 / 5 of that of lead-acid products. Lithium battery the service life rate of lithium battery is very low, which is one of the most prominent advantages of the battery. Generally, it can be listed below 1% / month, not 1 / 20 of that of Ni MH rechargeable battery. Lithium battery has strong adaptability to high and low temperature, and can be applied in the natural environment of - 20 ℃ - 60 ℃. After the solution of processing technology, it can be applied in the natural environment of - 45 ℃. Lithium batteries are low-carbon and environmentally friendly. No matter they are manufactured, applied or damaged, they do not carry or cause all harmful heavy metal elements and chemicals such as lead, mercury and cadmium. Lithium battery production does not consume water, which is very beneficial to those with less water in China.
Disadvantages of lithium battery:
1. Lithium primary batteries have poor safety and risk of explosion accidents.
2. Lithium ion battery of lithium cobalt oxide battery can not be charged and discharged with large current, which is expensive and has weak safety.
3. All lithium-ion batteries need to maintain the route to avoid overcharge and overcharge and discharge of the battery.
4. High manufacturing standards and increased costs.
5. The application standard is limited, and the application risk of high and low temperature is high.
