Lithium batteries are better. Lithium batteries are more than 3 times better than lead-acid batteries in terms of specific energy by volume and specific energy by weight. Lithium batteries are smaller and lighter in weight. Lithium batteries can achieve more than 800 cycles using lithium iron phosphate cathode material; lithium batteries are better. Lithium-ion batteries are lighter in weight and have a higher specific energy, but are safe and cost-effective. Lithium-ion batteries are alkaline batteries with a cycle life of over 2,500 cycles and lead-acid batteries with a cycle life of around 800 cycles. In other words, at the same weight; lead-acid batteries "lead-acid batteries are safe. The larger the capacity of lithium batteries, the worse the heat dissipation, which means that they are more likely to spontaneously combust or explode, while lead-acid batteries are composed of lead pole plates, the capacity is not as good as lithium batteries, but the performance is relatively stable and not easy to spontaneously combust or explode, so "lead-acid" will be safer.
1. Service life First of all, the service life of lithium batteries, high safety, in pinprick, short-circuit extrusion and other harsh conditions are still safe and not deformed, good performance, can be used at high temperatures without affecting the service life of the case, so lithium batteries than lead-acid batteries longer service life
2. The biggest problem of lead-acid battery range is its own energy density; lithium and lead-acid batteries have their own advantages and disadvantages, you can't just say which is good, the key depends on the user's needs and uses, suitable for their own riding mode of operation is the best. Relatively speaking, the technology of lead-acid batteries is more mature and cheaper, especially in terms of safety. Lithium battery technology; lithium batteries are more advanced than lead-acid batteries. Clean and environmentally friendly, we all know that lead is a heavy metal, so the production of lead-acid batteries will have a great impact on the environment, while lithium batteries are not good either in the production process or in use, causing environmental pollution. In summary, lithium batteries have a long service life battery life has a greater impact on the environment; that is, at the same weight, lithium batteries run farther than lead-acid batteries. Therefore, in terms of energy density, lithium batteries are better than lead-acid batteries. In terms of service life, a good quality lithium battery can generally be cycled about 1000 times, while a lead-acid battery is only about one-third of a lithium battery. In terms of price and safety of lead-acid batteries, lithium batteries are not as good as lead-acid batteries in terms of environmental protection, and lithium batteries are better than lead-acid batteries. On the whole, lithium batteries are better.
Recently, some friends asked whether it is better to choose lead-acid batteries or lithium batteries for electric vehicles. In fact, there is no absolute certainty on this issue. Let's look at the advantages and disadvantages of each first, and then draw a conclusion. Compared with lead-acid batteries
1. lithium batteries have a higher average voltage and higher energy density, in other words, the same size of battery;
Pros
2. repairable, as opposed to lithium batteries which are disposable and can only be replaced when broken, while lead-acid batteries have electrolyte water loss that can be replenished, and battery ageing can be repaired with pulse technology. As a repairable battery, it is more convenient to use and more cost-effective.
Advantages
3. Recyclable. Lead-acid batteries are not "scrap" at the end of life; lead-acid batteries are more advantageous from a cost perspective, because the price of lithium batteries is generally 2 to 3 times that of lead-acid batteries, which means that if you choose a new lithium battery, the cost will be greatly increased, while lead-acid batteries are relatively economical. In addition, lithium batteries are not easy to recycle and have low recycling costs, while lead-acid batteries can be recycled.
What is the difference between lithium batteries and lead-acid batteries?
1. Lithium batteries are better. In fact, there is no essential difference between the two in terms of principle. There will be a big difference between the two in terms of life applications. The difference between the two is reflected in their use; that is, lithium batteries run farther than lead-acid batteries at the same weight. Therefore, in terms of energy density, lithium batteries are superior to lead-acid batteries. In terms of the service life of lead-acid batteries, a set of good quality lithium batteries can be cycled up to about 1000 times, while lead-acid batteries are only about one-third of lithium batteries. Well, it's still relatively good.
Firstly, in terms of price, generally speaking, a lead-acid battery of the same type will cost less than a lithium battery, which means that it will be more cost-effective to replace a set of batteries. In addition, lead-acid batteries are more expensive to recycle than lithium batteries because they can be; the two types of batteries are comparable. Contamination during production and use. There is contamination in production. Lead-acid batteries contain high levels of lead and acid. High.
