Analyze the difference between lithium-ion batteries and lead-acid batteries

1 Safety comparison, the safety of power lithium-ion batteries (lithium manganate, lithium iron phosphate) varies with different materials. Lead-acid battery technology is more mature and safer than lithium-ion batteries. 2. Compared with environmental protection, lithium-ion batteries are pollution-free, while lead-acid batteries have heavy metal lead pollution. Therefore, electric vehicles using lead-acid batteries will still pollute the environment. 3. Price comparison, the price of lithium-ion batteries with the same capacity on the market is more than twice that of lead-acid batteries. This is why electric vehicles using lithium-ion batteries are more expensive. dghoppt.com 4. The mass ratio, volume ratio and energy ratio of lithium-ion batteries are about 40% higher than those of lead-acid batteries. 5. The self-discharge rate of lithium-ion batteries is less than 3%, while the self-discharge rate of lead-acid batteries is 15-30%. 6. Service life comparison, at present, ordinary lithium iron phosphate has no memory effect when it is charged 1500 times. After 1500 recharges, the storage capacity of lithium iron phosphate batteries is about 85%, while the storage capacity of lead-acid batteries is about 500 times, and the memory effect is very obvious. Therefore, the battery life of electric vehicles using lithium-ion batteries will be longer. 7. The voltage platform of lithium-ion batteries is higher than 3V, and the voltage platform of lead-acid batteries is 2V. In short, for batteries with the same capacity and high current discharge, lithium-ion batteries discharge about 30% more power than lead-acid batteries.
