Comparison of advantages and disadvantages between lithium battery and lead-acid battery

At present, the common electric vehicle batteries on the market are lithium batteries and lead-acid batteries. Lead-acid batteries and lithium batteries have their own unique advantages and disadvantages. There is no better way to say that only one is more suitable for them. After all, everyone's usage is different. I suggest that you can refer to the advantages and disadvantages of lead-acid batteries and lithium batteries, and choose an electric vehicle battery that is more suitable for you in combination with your actual use. The following are their advantages and disadvantages:

Advantages of lead-acid batteries:

1, with good safety performance. Lead-acid batteries are easy to charge, so they can be used after a little repair.

2, the price is cheap. The price of lead-acid battery is about 1/3 of that of lithium-ion battery, which shows its low price.

3. Recoverable reverse repair. Lead-acid batteries are highly recyclable. After being worn out, you can go to the electric car shop to trade in the old one for the new one, and make up the difference for a new battery, so as to minimize the loss, which is no small benefit to users. Lead in batteries can also be recycled, reducing environmental pollution.

Disadvantages of lead-acid battery: heavy weight, limited battery capacity and short service life. Generally, lead-acid batteries are charged and discharged within 400 times, and their service life is about three years.

Advantages of lithium-ion batteries:

1: light weight and small volume. The volume of lithium-ion battery is 2/3 of that of lead-acid battery, and its weight is about 1/3 of that of lead-acid battery. The capacity of lithium-ion battery with the same volume is higher than that of lead-acid battery, and the weight reduction makes the electric vehicle lighter, and the endurance is improved by about 10%.

2: Long life. The average life of lithium-ion batteries is about 4 years, which is about one year longer than that of lead-acid batteries. After charging and discharging for more than 500 times, the battery has no memory and strong shock resistance.

3: Overcharge resistance, good charge and discharge resistance. At room temperature, the lithium-ion battery can be continuously charged for 48 hours, and there will be no accidents such as battery expansion, liquid leakage and rupture, and the capacity will remain above 95%. And under the special charger, it can be charged and discharged quickly.

Disadvantages of lithium-ion batteries:

Lithium-ion battery has high production cost and expensive production equipment. The labor cost accounts for about 40% of the production cost, and the price is about 3 times that of lead-acid batteries. The cost performance brought by its triple price is not high, giving people a sense of flashy. Moreover, lithium-ion batteries are non-recyclable. When they are worn out, they can only be thrown away or buried in one place. Thousands of years later, later generations dug them up and they became antiques.

The safety performance of lithium battery is worse than that of lead-acid battery, especially at high temperature, which is prone to fire, spontaneous combustion, explosion and other dangers.

Considering the quality, after-sales service and price of battery products, we recommend a very good brand of lead-acid battery: Changxin battery.

Changxin battery, as an old lead-acid battery production group, has been praised by the market for its excellent reputation and quality for many years. As a high-end product in lead-acid batteries, Changxin Graphene Series adopts a more scientific in-line structure and an upgraded formula with higher energy density and high technology content, which brings longer life, longer battery life and more stable performance.
