Which is better, 18500 battery or lead-acid battery?
1. Volume energy density ratio: Generally speaking, the net weight of lead-acid batteries is 16-30kg, which is very large; the net weight of lithium batteries is kg, the relative volume of lithium batteries is relatively small, and the relative volume density of lithium batteries is generally lead Twice as acid battery, so lightweight and easy to transport. The specific energy of lithium-ion batteries is 200260h/g, and that of lead-acid batteries is 5070h/g. The relative density of lithium-ion batteries is 35 times that of lead-acid batteries.
2. Manufacturing cost: The cost of lithium-ion batteries is much higher than that of lead-acid batteries. The cost of assembly of auxiliary materials and external electronic control systems is low. Due to the continuous development of processing technology, the labor cost of lithium ion is getting higher and higher. Among the manufacturing costs, the labor cost of lithium-ion batteries is higher than 40%, while the labor cost of lead-acid batteries is generally 10% to 20%.
3. Recycling value: Industrial equipment used to produce and manufacture lithium-ion packaging is expensive, has high use value, and has high depreciation and losses of mechanical equipment. The entire process of lithium-ion batteries is irreversible, while lead-acid batteries are reversible and reusable. After the application of lead-acid batteries, its collection and use value is more than 40%, and the collection and use value of lithium ions is basically zero.
4. Use cycle: The frequency of the ternary drive lithium-ion battery cycle system is greater than 1000 times, the frequency of the lithium-ion battery cycle system is greater than 2000 times, the frequency of the lead-acid battery cycle system is only 300350 times, the lithium-ion battery cycle system is cycled in 2000 The final volume is still greater than 80%, and the service life is greater than 800 times. Therefore, the usage of lithium-ion batteries is 3-6 times that of lead-acid batteries.
5. Price: At this stage, lithium-ion is more expensive than lead-acid batteries, about three times and lower than lead-acid batteries. However, according to fusion life analysis, the same capital investment cost still means that lithium-ion has a longer application cycle.
6. Scope of application: Since the safety factor is slightly lower than that of lead-acid batteries, lithium-ion batteries must be suitable for various safety precautions, such as avoiding damage to lithium-ion batteries from external forces or safety accidents, because this may cause fire or; lithium-ion batteries The current range is also very good, so that in other adaptation levels lithium-ion batteries are not inferior to lead-acid batteries.
7. Policy: Lead-acid batteries cause serious harm to the environment due to the production process or discarded batteries. Therefore, from a policy perspective, the expansion and reinvestment of lead-acid batteries has been restricted, or lead-acid batteries have been restricted in certain areas. usage of. However, lithium-ion batteries are environmentally friendly and a zero-pollution process. In the future, the replacement of lithium-ion batteries will become more and more important, and progress will be accelerated.
8. Environmental protection: Lithium-ion batteries cause less environmental pollution than lead-acid batteries! Lithium-ion batteries are greener than ordinary rechargeable batteries, with very little air pollution, no excessive heavy metals and non-ferrous metals, and zero pollution in production and application, which can prevent ordinary rechargeable batteries from polluting the natural environment.
Generally speaking, lithium batteries have greater advantages and their promotion and application will be more common.
