1. Safety comparison: the safety of power lithium batteries (lithium manganate, lithium iron phosphate) varies with different materials. The technology of lead-acid battery is relatively mature, and its safety is higher than that of lithium battery.
2.Compared with environmental protection, lithium battery has no pollution, while lead-acid battery has heavy metal lead pollution. Therefore, electric vehicles using lead-acid batteries will still pollute the environment.
3. Compared with the price, the price of lithium battery with the same capacity in the market is more than twice that of lead-acid battery. This is why electric cars with lithium batteries are more expensive. dghoppt. com
4.The mass ratio, volume ratio and energy ratio of lithium battery are about 40% higher than that of lead-acid battery.
5. The self discharge rate of lithium battery is less than 3%, while that of lead-acid battery is 15-30%.
6.Compared with the service life, at present, ordinary lithium iron phosphate has no memory effect when charging 1500 times. After 1500 times of charging, the storage capacity of lithium iron phosphate battery is about 85%, while the storage capacity of lead-acid battery is about 500 times, and the memory effect is very obvious. Therefore, the battery life of electric vehicles using lithium batteries will be longer.
7.The voltage platform of lithium battery is higher than 3V, and that of lead-acid battery is 2V. In a word, lithium batteries with the same capacity discharge about 30% more electricity than lead-acid batteries with high current discharge.
8.The battery life is more than 500 years. Its battery life is more than 500 years. Lead acid batteries usually use the memory to charge and discharge less than 400 times, with a service life of about two years. If a maintenance free lead-acid battery is used, it should be noted that the water loss of the battery is small, and distilled water is not required during use.
