Correctly compare lead-acid batteries and lithium batteries, which one is better?

With the renewal and iteration of electric vehicle battery technology and policy control, the development of lithium batteries is bound to become the mainstream trend in the future. The position of gradually replacing lead-acid batteries is affirmative, but lithium batteries are still limited by their own performance, cost-effectiveness and other reasons. There is still a way to go to completely replace the leading position of lead-acid batteries, and lead-acid batteries I am also constantly making self-breakthroughs. Therefore, if you want to completely replace it, it is still impossible for now. After all, lead-acid batteries are industrialized and mass-produced for a longer time, and they are cheap and non-flammable. Replaced by batteries. Except for the environmental pollution problem and bulky body of lead-acid batteries, lead-acid batteries hardly have any other shortcomings. The following electric vehicle lithium battery manufacturer electronics will give a general introduction about which is better, lead-acid battery or lithium battery. Below, we will analyze and explain separately for lithium iron phosphate batteries, lead-acid batteries and lithium-ion batteries. First analyze the lithium iron phosphate battery 1. Durability: The lithium iron phosphate battery has strong durability, slow consumption, charge and discharge more than 2000 times, and has no memory, and the general life span is 4-5 years. 2. Discharge rate: Lithium iron phosphate battery can be discharged with high current, suitable for electric vehicles, electric bicycles, etc. 2. In terms of volume and quality: Lithium batteries are relatively small in size. 3. Battery capacity: The capacity of lithium batteries in the same volume is larger than that of lead-acid batteries. The lead-acid battery has a capacity of about 20 amps; the lithium battery has a capacity of 8-10 amps. 4. No memory effect: Lithium iron phosphate battery can be charged and used at any time, no matter what state it is in. 5. Nominal voltage of monomer: Nominal voltage of lithium iron phosphate battery: 3.2V. 6. Environmental protection: The material does not contain any toxic and harmful substances. It is regarded as a green battery in the world. The battery has no pollution in production and use, and has become a hot research topic. 7. Safety: Lithium iron phosphate has passed strict safety tests and will not explode even in the worst traffic accidents, showing higher safety performance. The safety of lithium iron phosphate batteries is closest to that of lead-acid batteries. In the future, lithium iron phosphate batteries are most likely to replace lead-acid batteries. Lead-acid batteries 1. Lead-acid batteries are generally deep-charged and discharged within 300 times, have memory, and have a lifespan of about two years. Moreover, there is liquid in the lead-acid battery. After a period of consumption, if the battery is found to be hot or the charging time becomes shorter, you need to replenish the liquid. 2. Generally, lead-acid batteries weigh 16-30 kilograms and are relatively large. 3. Lead-acid batteries contain a large amount of lead. If they are not handled properly after being discarded, they will pollute the environment and cause pollution during the production process. 4. Nominal voltage of lead-acid battery cell: 2.0V5. Because lead-acid battery uses non-flammable diluted sulfuric acid as the electrolyte, even in the harshest environment, the battery itself will not burn. , Lead-acid batteries are not sensitive to overcharge and overdischarge. In addition to damaging the capacity and life, they will not be as fierce as a lithium ion battery after overcharge and overdischarge. The safety of use is much higher than that of lithium batteries. This is the current comparison of lead-acid batteries and lithium batteries that cannot be replaced by lithium batteries. Lithium-ion batteries: The cycle life can reach 800-1000 times and the service life is longer. Although lithium batteries need to cost more when they are newly purchased, a single The cost performance of average cycle loss is more than 4 times that of lead-acid batteries; for the same size battery, lithium-ion batteries have a larger battery capacity; under the same capacity, the volume of lithium-ion batteries is 2/3 of the volume of lead-acid batteries, and the weight It is 1/3 of the weight of lead-acid battery; lead-acid battery: cycle life is less than 300 times, the service life is short, and the cost performance is lower; the battery capacity is relatively limited; the volume and weight are relatively large under the same specification and capacity; no large current is fast Charging and discharging performance; there are a lot of lead and a lot of acid in the battery, if it is disposed of improperly, it will pollute the environment. In summary, the different advantages of lithium batteries and lead-acid batteries also represent the different characteristics of the two batteries. Therefore, if environmental protection factors are aside, lead-acid batteries still have a superior price-performance ratio. If it is not for policy adjustments, I believe that lead-acid batteries will still occupy the mainstream position in the market for a long time, but environmental factors cannot be delayed. In the future, we Cleaner energy is needed to avoid environmental pollution. Pollution-free and pollution-free new energy is the most effective guarantee in the future. With the passage of time and technological progress, I believe that in the near future, lithium battery technology will be safe or Performance, will catch up with and surpass lead-acid batteries to become the mainstream of the market. For now, the high capacity and portability of lithium batteries are gradually replacing lead-acid batteries. I believe that after reading this article, you are more likely to choose between lead-acid batteries and lithium batteries.
