Advantages and disadvantages of lead-acid batteries and lithium batteries
Advantages of lead-acid batteries.
1、Good safety performance. Lead-acid batteries are good to maintain, you can drop and hit, a little repair, you can continue to use.
2, the price is cheap. Lead-acid battery price is about 1/3 of the lithium battery, so its price is low.
3、Recyclable reverse repair. Lead-acid batteries can be recycled, after the use of bad can go to the electric car store to exchange the old for a new, make up the difference can be replaced by a new set of batteries, to minimize the loss, the user is a considerable benefit. The lead in the battery can also be recycled and reused, reducing environmental pollution.
Disadvantages of lead-acid batteries.
Heavy weight, limited battery capacity, short life span, lead-acid batteries are generally within 400 times of deep charging and discharging, with a life span of about two years.
Advantages of lithium battery.
1, light weight, small size. The volume of lithium battery is 2/3 of the volume of lead-acid battery, the weight is about 1/3 of the weight of lead-acid battery. the same volume of lithium battery is higher than the capacity of lead-acid battery, the reduction of weight makes the electric car lighter, the range also increased about 10%.
2、Long life. The average life of lithium battery is about 4 years, about 1.5 times higher than the life of lead-acid batteries, charging and discharging more than 500 times, the battery use no memory, strong shock resistance.
3, overcharge resistance, good performance of charge and discharge resistance. Lithium battery at normal temperature, lithium batteries can be continuously charged for 48 hours without accidents such as battery expansion and leakage rupture, the capacity is maintained at more than 95%. And under the special charger, you can carry out rapid charging and discharging.
Disadvantages of lithium batteries.
The production cost of lithium batteries is high, the production equipment is expensive labor costs account for about 40% of the production cost, the price is about three times the price of lead-acid batteries. At the same time, lithium batteries are not recyclable, and can only be thrown away when they are broken. There is also an important issue is the existence of lithium batteries fire and explosion safety hazards, especially in the case of consumers unknowingly cheated by crooks led to the purchase of poor-quality lithium batteries, in electric vehicles such as sealing conditions are not too good, easy to wet lead to poor contact and other causes of safety hazards.
