With the update of electric vehicle battery technology, the development and application of lithium batteries have increased year by year. However, it is only rising. Due to the performance and cost performance of lithium batteries, there is still a long way to go to replace the status of replacing the traditional lead-acid battery brother. Which is better for lead-acid batteries and lithium batteries? For the future development of lithium batteries, what is the prospect? Relevant experts said that the lead-acid battery will still occupy the dominant position of electric bicycle power battery in the future.
There are three types of batteries commonly used in electric bicycles, lead batteries, nickel-hydrogen batteries, and lithium-ion batteries. Lithium battery electric bicycle is very light and has a long electricity consumption. What are the advantages and disadvantages compared with lead batteries?
1. Half of the price of an electric car is on the battery. Lithium batteries are much more expensive than lead-acid batteries, and lithium electric vehicles are much more expensive.
2, the quality is also the endurance time is long, can run farther than the lead-acid battery.
3, must pay attention to waterproof during use, it is more difficult to serve than lead-acid batteries. The manganese dioxide of the positive electrode of a lithium battery can be heated only by a small drop of water. After the contact of sulfur chloride in the lithium battery with water, the heat energy is released while generating hydrochloric acid and sulfur dioxide. Several factors make the lithium battery a "fire" in life, and must pay attention to waterproof and moisture when using the lithium battery.
4. I personally think that although there are already lithium electric cars in the market, the sales volume is not very satisfactory and is not recognized by the public. From an environmental point of view, lithium batteries are more environmentally friendly than lead acid.
5, lead-acid batteries can now be repaired, including instruments plus manual maintenance, lithium batteries I do not know if it can be repaired.
Which is better for electric vehicle lead-acid batteries and lithium batteries? In contrast, lead-acid battery technology is mature, and 75% of raw materials can be recycled, so the price is relatively cheap, which is more suitable for the purchasing ability of electric bicycle consumers. Although the proportion of lithium-ion batteries will increase in the future, lead-acid batteries will still dominate the electric bicycle power battery. Lithium batteries need a long way to replace the dominant position of lead batteries.
