Which one is better, lead-acid battery or lithium battery?

1. Lithium batteries are light in weight, high in specific energy, but high in safety and cost-effective; the same lead-acid battery is heavy, large in size, small in specific energy, but safe and cost-effective; 2. Lithium batteries are rechargeable batteries , And lead-acid batteries are alkaline batteries; lithium batteries have a cycle life of more than 2500 times, and lead-acid batteries have a cycle life of about 800 times; lithium batteries are about 150Wh/kg, and lead-acid batteries have a specific energy of about 40Wh/kg; lithium battery charging It can be overflowed within 4h, while the charging time of lead-acid batteries is generally around 6h; 3. Lithium battery charge and discharge power efficiency is better, lithium battery charge and discharge power conversion efficiency can be greater than 97%, while lead-acid battery charge and discharge The energy conversion efficiency is about 80%. The same lithium battery is smaller than the lead-acid battery. The volume of the lithium battery is about 2/3 of the volume of the lead-acid battery; 4. The lithium battery power is environmentally friendly, and the lead-acid battery is non-environmentally friendly There is a large amount of lead in batteries and lead-acid batteries. If they are not properly solved after being discarded, they will pollute the environment. Under the same voltage and capacity, lithium batteries and lead-acid batteries have the same mileage, but the price of lithium batteries will be higher than that of lead. Acid batteries are more than twice as expensive; 5. Lead-acid batteries are very harmful to the environment due to processing or discarded batteries. National policies have restricted the reinvestment of lead-acid batteries, or restricted lead-acid in certain areas. With the use of batteries, the trend of replacing lead-acid batteries with lithium batteries in the future will become clearer, and the progress will gradually accelerate. Many lead-acid batteries will be replaced by lithium batteries, so lead-acid batteries are slowly withdrawing from the stage of lithium batteries. Lead-acid batteries have low cost and mature receiving and receiving mechanism, low internal resistance, low working requirements, no need to care for the circuit, and almost no maintenance, so the foundation is lead-acid under severe conditions. Batteries are not lithium batteries, but they also have low specific capacity, high mass and volume, and low charging power. With the growth of lithium batteries in the future, lead-acid batteries will become narrower and narrower. Nowadays, the standard equipment is lithium batteries. Although the mistakes are well known, problems such as bulging, burning and explosion are endless, but until now, there is still no battery that can exceed the lithium battery in terms of capacity and charging times, especially For ternary lithium batteries, although BYD’s lithium iron phosphate batteries are more secure, the gap in capacity can still only leave a part of the Enron problem behind. Lithium batteries and lead-acid batteries are both energy storage batteries, but they are two kinds of rechargeable batteries with completely different characteristics, and the output characteristics are also very different, so they cannot be used together at the same time, unless they can be used separately , But must meet the technical requirements, including protective measures.
