Comparison between lead-acid battery and lithium battery

Electric vehicle battery technology upgrade, lithium battery development is fast. But it's only going up. Restricted by their own performance, cost-effectiveness and other reasons to replace the lead-acid battery big brother's status has a long way to go, and the boss lead-acid batteries are also constantly making self-breakthrough.

The obvious advantages of lead-acid batteries are as follows:

Number one, cheap! The reason why the lead boss can cross the rivers and lakes for many years and sit in the position of the boss is all because of this reason! Cheap, except cheap or cheap.

Second, the recast furnace(recyclable reverse repair) lead-acid batteries bring their own recycling skills. After they are broken, they can be replaced by old ones in electric car stores, and the difference can be replaced with a new set of batteries to minimize losses. It is a great benefit and benefit to the user.

What are the disadvantages of lead-acid batteries, such as large volume weight, limited battery capacity, and short life, lead-acid batteries are generally within 400 deep discharge, the life span of about two years?

For lead-acid batteries, there is also a trend to lease battery use, save the heart and cost-effective, but also very convenient, traction lease battery model is gradually rising, all over the country is gradually popular!

What are the advantages of lithium batteries?

First, lightweight and small body size. Compared with lead-acid batteries of the same capacity on the market, lithium batteries have a volume of 2/3 of the volume of lead-acid batteries and a weight of approximately 1/3 of the weight of lead-acid batteries. Lithium batteries of the same volume have higher capacity than lead-acid batteries, and weight loss has increased the battery's endurance by about 10 %.

Second, durability, life expectancy. The average life span of lithium batteries is about 4 years, which is about 1.5 times higher than that of lead-acid batteries. It has more than 500 charge and discharge times and has strong earthquake resistance.

Third, overcharge resistance, high discharge resistance. At normal temperatures, lithium batteries can be continuously charged for 48 hours without accidents such as battery expansion and leakage rupture, and the capacity is maintained at more than 95 %. And under the special charger, you can carry out rapid charging and discharging.

Although lithium batteries have many benefits, their disadvantages are also more obvious, such as:

The cost of making lithium batteries is high. The expensive labor cost of making equipment accounts for about 40 % of the production cost and the price is about three times that of lead-acid batteries. The price of its triple price is not high, and the recycling utilization rate of lithium batteries is low. If it is broken, it can only be thrown away, or it can be buried in a place. After thousands of years, it will be dug up by later generations. It is an antique.

The most important problem is that lithium batteries have potential fire explosion safety hazards, especially when consumers are unwittingly deceived by profiteers to purchase low-quality lithium batteries. The sealing conditions for electric vehicles are not too good. Easy dampness leads to poor contact and other causes of possible safety hazards. However, the technical performance of lithium batteries is also constantly improving, and safe materials are gradually being used.
