What are the differences between lead-acid/lithium battery electric vehicles?

1. Durability/battery life: The service life of lead-acid batteries is generally about 2 years, while lithium batteries are more durable, with a life span of 4-5 years; and lead-acid batteries are generally fully charged and discharged within 300 cycles, while lithium batteries The number of full charge and discharge cycles exceeds 500 times. 2. Lithium batteries are much smaller in volume and mass than lead-acid batteries. Under normal circumstances, lead-acid battery packs weigh 16-30 kilograms and have a larger volume; while lithium batteries generally weigh 2.5-3.0 kilograms and volume. It is relatively small, so it is light to ride and easy to carry. Generally, lithium battery electric vehicles are light and beautiful, easy to move, and many lithium battery electric vehicles can also be folded. 3. Spontaneous combustion and explosion of electric vehicles often occur, most of which are caused by battery charging and discharging. Once the lead-acid battery is overcharged, it will increase the probability of explosion. The current lead-acid battery on the market does not have any overcharge protection, which makes the lead-acid battery during charging, especially the lead-acid battery at the end of charging, extremely dangerous. 4. Driving kilometers/battery capacity: In the case of the same 48V battery, both lead-acid batteries and lithium battery electric vehicles can travel 30-40 kilometers, and the speed depends on the size of the motor used. The capacity of the lead-acid battery is about 20 ampere hours; the capacity of the lithium battery is arbitrarily configured. In the context of the country's emphasis on the use of lithium batteries for low-speed electric vehicles, the price of lithium batteries will certainly drop. Although lithium battery technology is mature, domestic manufacturers have not yet reached the stage of low-cost research and development of lithium battery positive and negative materials. In the next three to five years, the price of lithium batteries may be difficult to compete with lead-acid batteries. From the perspective of prices and policies, it will be a trend to replace lead-acid batteries with lithium-ionized low-speed electric vehicles in the future, but there will be a longer process. Due to mature technology and its characteristics, lead-acid batteries will be more stable and easier to be accepted by users. The lithium battery is still an emerging product in the electric vehicle industry, and the supporting facilities in all aspects are not very complete. Therefore, its stability is not as good as that of lead-acid batteries, and it is not easy to be accepted by users. Therefore, from this point of view, electric vehicles will not fully enter the era of lithium batteries in a short time.
