This article takes you to understand which is better for electric vehicle lead-acid batteries or lithium batteries



With the renewal of electric vehicle battery technology, the development and application of lithium batteries are increasing year by year. However, it is only an increase, and there is still a long way to go to replace the traditional lead-acid battery due to the performance and cost-effectiveness of lithium batteries. Which is better, lead-acid battery or lithium battery? Regarding the future development of lithium batteries, what are the prospects? Relevant experts talked about the "lithium battery" trend of electric bicycles and said that in the future, lead-acid batteries will still occupy the leading position of electric bicycle power batteries.




There are three types of batteries generally used in electric bicycles: lead storage batteries, nickel-metal hydride batteries, and lithium-ion batteries. Lithium battery electric bicycles are very light and have a long battery life. What are the advantages and disadvantages compared with lead batteries?




1. Half the price of an electric vehicle is on the battery. Lithium batteries are much more expensive than lead-acid batteries, and lithium electric vehicles are also much more expensive.




2. In terms of quality, it has long battery life, which can run farther than lead-acid batteries.




3. Be sure to pay attention to waterproofing during use, which is more difficult to service than lead-acid batteries. The manganese dioxide in the positive electrode of a lithium battery can generate heat with only a small drop of water. After the sulfurous chloride in the lithium battery comes into contact with water, it generates hydrochloric acid and sulfur dioxide and releases heat at the same time. Several factors make the lithium battery a "fire" in life. When using a lithium battery, you must pay attention to waterproof and moisture-proof.




4. I personally think that although there are already lithium batteries on sale, the sales volume is not very satisfactory and is not recognized by the public. From an environmental perspective, lithium batteries are more environmentally friendly than lead-acid.




5. The lead-acid battery can be repaired now, including the instrument plus manual repair. I don't know if the lithium battery can be repaired.




Which is better for lead-acid batteries or lithium batteries for electric vehicles? In contrast, lead-acid batteries have mature technology and 75% of the raw materials can be recycled, so the price is relatively cheap and more suitable for the purchasing power of electric bicycle consumers. ?Although the proportion of lithium-ion batteries will increase in the future, lead-acid batteries will still dominate the power battery of electric bicycles. It will take a long way for lithium batteries to replace the dominant position of lead-acid batteries.
