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

1. Safety comparison, different materials (lithium manganate and lithium iron phosphate) of power lithium-ion battery have different safety. Lead-acid battery technology is quite mature and safer than lithium-ion batteries. 2. Compared with environmental protection, lithium ion batteries are not polluted, and lead-acid batteries are polluted by heavy metal lead. Therefore, electric vehicles using lead-acid batteries will still pollute the environment. dghoppt.com/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. 4. Energy comparison, the mass ratio, volume ratio and energy ratio of lithium-ion batteries are about 40% higher than that of lead-acid batteries. 5. Comparing the self-discharge rate, the monthly self-discharge of lithium-ion batteries is less than 3%, while that of lead-acid batteries is 15-30%, which is quite different. 6. Comparing the service life, the current general lithium iron phosphate charge has no memory effect after 1500 times. The storage capacity after 1500 times is about 85%, while the lead-acid battery is about 500 times, the storage capacity will be greatly reduced, and the memory effect is obvious. Therefore, the battery life of electric vehicles using lithium-ion batteries will be longer. 7. Comparison of voltage platforms, the voltage platform of lithium-ion batteries is greater than 3V, and the voltage platform of lead-acid batteries is 2V. 8. Comparison of discharge characteristics. To put it simply, lithium-ion batteries discharge about 30% more electricity than lead-acid batteries under high current discharge. 9. Durability, lithium ion battery has strong durability and good impact resistance. A fully charged battery is safe and fixed, consumes slowly, charges and discharges more than 500 times, has no memory, and has a general life span of 4-5 years. Lead-acid batteries are generally charged and discharged within 400 times, with a memory and life span of about two years. If you use a maintenance-free lead-acid battery, it should be noted that the battery loses less water, and generally do not distill water when using it.
