Which is better between lead-acid batteries and lithium-ion batteries?
1. Lithium ion batteries are lightweight and have a high specific energy, but they have high safety and cost-effectiveness; Equivalent lead-acid batteries are heavy in weight, large in volume, and have low specific energy, but they have good safety and high cost-effectiveness;
2. Lithium ion batteries belong to rechargeable batteries, while
lead-acid batteries belong to alkaline batteries; The cycle service life of lithium-ion batteries is more than 2500 times, and the cycle service life of lead-acid batteries is about 800 times; Lithium ion batteries have a specific energy of around 150Wh/kg, while lead-acid batteries have a specific energy of around 40Wh/kg; Lithium ion batteries can be fully charged within 4 hours of charging, while lead-acid batteries generally take around 6 hours to fully charge;
3. In terms of charging and discharging energy efficiency, lithium-ion batteries have better performance. The energy conversion efficiency of lithium-ion batteries can be greater than 97%, while that of lead-acid batteries is about 80%. Similarly, lithium-ion batteries have a smaller volume than lead-acid batteries, with a volume of about 2/3 of that of lead-acid batteries;
4.
Lithium ion batteries are environmentally friendly for power, while lead-acid batteries are non environmentally friendly. Lead acid batteries contain a large amount of lead, which, if not properly disposed of after disposal, will pollute the environment. Under the same voltage and capacity, the range of lithium-ion batteries and lead-acid batteries is much the same, but the price of lithium-ion batteries will be more than twice that of lead-acid batteries;
5. The harm of lead-acid batteries to the environment caused by production processes or discarded batteries is quite serious. National policies have already restricted the expansion and reinvestment of lead-acid batteries, or restricted the use of lead-acid batteries in certain fields. In the future, the trend of replacing lead-acid batteries with lithium-ion batteries will become more obvious, and the progress will gradually accelerate. Many lead-acid batteries will be replaced by lithium-ion batteries, so lead-acid batteries are slowly withdrawing from the lithium-ion battery stage.
Lead acid batteries have a low cost and a mature receiving and receiving mechanism, low internal resistance, and do not require high requirements before operation. They do not require circuit protection and can almost be truly maintenance free. In harsh situations, the foundation is mostly lead-acid batteries rather than lithium-ion batteries, but there are also low specific capacity, large weight and volume, and low charging capacity. In the future, with the growth of lithium-ion batteries, the path of lead-acid batteries will become narrower and narrower.
Nowadays, lithium-ion batteries are commonly used as standard equipment. While errors such as bulging, combustion, and explosion are common, there is still no battery that can surpass lithium-ion batteries in terms of capacity and charging times, especially ternary lithium-ion batteries. Although BYD's iron phosphate lithium-ion batteries are more reliable, the capacity gap can only partially ignore safety issues.
