Which is better between lithium ion battery and lead-acid battery

1. Comparison of volumetric energy density between lithium-ion batteries and lead-acid batteries. Since the energy density of lithium-ion batteries is 3 to 5 times that of lead-acid batteries, under the same capacity, the volume of lithium-ion batteries is smaller than that of lead-acid batteries. About 30%-50%. 2. Comparison of lithium ion battery and lead-acid battery in terms of weight energy density. Lead-acid battery has a specific energy density of 60~80wh/g, a lithium-ion battery has an energy density of 200~260wh/g, and a specific energy lithium-ion battery is a lead-acid battery. Lithium-ion battery capacity is 3-5 times that of lead-acid battery under the same weight. Lithium-ion battery has an absolute advantage in energy density. 3. Comparison of lithium ion batteries and lead-acid batteries in terms of cycle life. At present, ternary lithium and lithium iron phosphate are the most widely used. For example, ternary lithium ion batteries can usually be cycled 500-1000 times. Lithium iron phosphate batteries have It can be cycled 2,000-3000 times, but lead-acid batteries usually can only be cycled 200-300 times. In other words, the cycle life of lithium-ion batteries is 2-10 times that of lead-acid batteries. 4. Comparison of lithium-ion batteries and lead-acid batteries in terms of price. Lead-acid batteries are currently cheaper than lithium-ion batteries, and the price of lithium-ion batteries is about 1.5-2 times that of lead-acid batteries. However, with the widespread application of lithium-ion batteries and the maturity of process technology, the cost is gradually reduced. Based on the comprehensive comparison of the cycle life of lithium-ion batteries, the use cost of lithium-ion batteries is lower. 5. Comparison of applicability between lithium-ion batteries and lead-acid batteries In terms of safety in use, lead-acid batteries are relatively more stable. Due to the material system of the lithium-ion battery, the lithium-ion battery is relatively active, and there is a risk of fire or explosion during use. For example, some external factors may cause the lithium-ion battery to be damaged due to accidents. Therefore, the lithium-ion battery must be installed properly. Equipped with special protection board. At present, lithium-ion batteries are not as safe as lead-acid batteries in terms of safety. 6. Comparison of environmental pollution between lithium-ion batteries and lead-acid batteries. As lead is a heavily polluted material, lead-acid batteries have serious pollution risks. Therefore, environmental pollution may be caused during the production process or discarding waste batteries. Therefore, with the development of national environmental protection actions, many unregulated lead-acid battery companies have been banned and shut down. The lithium-ion battery materials do not have heavy pollution materials, and the relative pollution is very small, which can be basically ignored.
