Comparative analysis of the advantages and disadvantages of lead-acid batteries and lithium batteries

The advantages of lead-acid batteries: 1. Good safety performance. Lead-acid batteries are easy to feed, so you can be beaten and beaten, and you can continue to use them after a little repair. 2. The price is cheap. The price of lead-acid batteries is about 1/3 of that of lithium batteries, which shows the low price. 3. Recyclable and reverse repair. Lead-acid batteries are highly recyclable. After being worn out, you can go to the electric car shop to exchange the old for a new one. If you make up the price difference, you can exchange for a new set of batteries, minimizing the loss, which is a great benefit to users. The lead in the battery can also be recycled, reducing environmental pollution. Disadvantages of lead-acid batteries: heavy weight, limited battery capacity, short lifespan, lead-acid batteries are generally within 400 times of deep charge and deep discharge, and the lifespan is about two years. Advantages of lithium batteries: 1: Light weight and small size. The volume of a lithium battery is 2/3 of the volume of a lead-acid battery, and its weight is about 1/3 of the weight of a lead-acid battery. Lithium batteries of the same volume have a higher capacity than lead-acid batteries, and the reduction in weight makes electric vehicles lighter, and their endurance has increased by about 10%. 2: Long life. The average life of a lithium battery is about 4 years, which is about 1.5 times longer than that of a lead-acid battery. It has more than 500 charge and discharge times. The battery has no memory and has strong shock resistance. 3: Overcharge resistance, good charge and discharge resistance. Under normal temperature, the lithium battery can continue to be charged for 48 hours without any accidents such as battery expansion, leakage and breakage, and the capacity remains above 95%. And under the special charger, it can charge and discharge quickly. Disadvantages of lithium batteries: The production cost of lithium batteries is high, and the expensive production equipment and labor costs account for about 40% of the production cost, and the price is about three times that of lead-acid batteries. The price-performance ratio brought by its triple price is not high, and it is quite flashy, and the lithium battery is not recyclable. If it is worn out, it can only be thrown away, or it can be buried somewhere. After thousands of years, later generations will dig it. It's an antique when it comes out. The most important problem is that lithium batteries have a fire and explosion safety hazard, especially when consumers are deceived by profiteers without their knowledge to buy low-quality lithium batteries. The sealing conditions in electric vehicles are not very good, and they are easy to be exposed to moisture. Defects and other reasons may cause potential safety hazards.
