Can lead-acid batteries be converted into lithium-ion batteries for electric cars?
The difference between the two:
The lead-acid battery material is hard and fall-resistant, the price is relatively cheap, 18650 pack builder and it has the advantage of recyclable reverse repair; However, due to the large volume but small capacity, the service life of the network is also short.
Lithium batteries are small in size, light in weight, large in capacity, long in service life, and good in charge and discharge resistance, but they are expensive, non-recyclable, and have safety risks.
Lead acid battery advantages:
hard: Lead acid boss China has always been in line with the principle of "he is strong by him, battery manufacturing machine the wind strokes the mountains, he is horizontal, he is horizontal, the moon shines on the river". Let you fall and beat, repair yourself a little, you can continue to learn to use, it is very good to support very much.
Cheap: Lead acid has long been the king of electric vehicle batteries, and the reasons can't be ignored. The price is about a third of the lithium-ion battery.
recyclable reverse repair: lead acid boss is a masterpiece. li ion battery construction You can go to the electric car shop to make up the difference, to replace the old, you can minimize the loss. For the user, it is not a great benefit.
the volume weight is large, but the capacity is relatively short.
The life is short, and the lead-acid battery is generally discharged 400 times during deep charging.
Advantages of lithium battery:
Light weight, small size: lithium batteries with small results are 2u002F3 of lead-acid batteries and 1u002F3 of lead-acid batteries compared with lead-acid batteries with the same capacity on the market. The same volume of lithium battery capacity is higher than lead-acid battery, the weight reduction makes the battery life of electric vehicles increased by about 10%.
Longevity: Lithium-ion batteries are good for your health. The average life of a lithium-ion battery is about four years, about 1.5 times that of a lead-acid battery. It can charge and discharge more than 500 times, and the battery has no memory and strong earthquake resistance.
Good charge and discharge resistance: the lithium battery is charged for 48 hours at room temperature, and the capacity remains above 95%. And under the special charger, it can be quickly charged and discharged.
Lithium battery disadvantages:
high price: lithium battery production enterprise cost is high, production technology and equipment expensive and labor management costs can account for about 40% of the cost of production time, the price is about three times that of lead-acid batteries, but through its three times the price of the cost is not high, quite give people the feeling of gaudiness.
Not recyclable: Lithium-ion batteries are not recyclable, and can only be thrown away when they are worn out, or buried somewhere, and thousands of years later, dug up descendants become antiques.
Safety risks: The main problem is that lithium batteries have fire and explosion safety risks, especially when consumers are unwittingly deceived by profiteers, resulting in the purchase of inferior lithium batteries. In electric vehicles, this sealing condition is not very good, and it is easy to be damp leading to poor contact, which may lead to possible safety hazards.
In short, lead-acid batteries and lithium-ion batteries have advantages and disadvantages. If you want to install a high-quality battery for your car, whether it is a lead-acid battery or a lithium-ion battery, or whether the battery manufacturer is trustworthy, be sure to choose a regular manufacturer.

When not in use, do lithium-ion batteries deteriorate?
Although lithium batteries don't necessarily go bad, they do lose a little bit of energy when they're just lying around. In particular, our LiFePO4 batteries deplete by 2-3% every month under the ideal circumstances.
