Comparison of the advantages and disadvantages of electric vehicle battery types

The first type: lead-acid batteries. As far as the current overall market situation is concerned, lead-acid batteries can be said to be the only one. Compared with other electric vehicle batteries, lead-acid batteries have low prices, low maintenance costs, sophisticated manufacturing processes, and performance. With many characteristics such as stability, good applicability, and high recycling rate, it currently accounts for about 90% of the electric vehicle battery market. In terms of its overall situation, lead-acid batteries generally charge and discharge about 400 times, and the theoretical cycle times are only about one-third of that of lithium-ion batteries. In addition, the overall lead-acid battery is relatively large in size and its weight is generally Lithium-ion batteries are more than twice, so the weight of the body that uses lead-acid batteries as the power of electric vehicles is much heavier than that of lithium-ion batteries, and the overall battery life is much shorter than that of lithium-ion batteries. With the implementation of the new national standard, there are brand-new regulations on the weight of electric vehicles, and lead-acid batteries have been affected to a certain extent. The second type of lead-acid battery: Lithium-ion battery For those who buy electric vehicles, lithium-ion batteries have many advantages compared to lead-acid batteries, such as lighter weight and more charge-discharge cycles. , High rated voltage, strong high temperature applicability, green environmental protection, etc. However, as far as the current market situation is concerned, there are certain hidden dangers in the safety of lithium-ion batteries. Sometimes there are fires. At the same time, lithium-ion batteries cannot be discharged with high current. The overall speed and safety performance are compared with lead-acid There is a big gap between batteries, and the overall price of lithium-ion batteries is higher than that of lead-acid batteries. However, with the implementation of the new national standard, lithium-ion batteries may become the first choice for electric vehicle batteries in the future. The third type of lithium ion battery: Ni-MH battery Ni-MH battery is a kind of battery with very good performance. Generally speaking, Ni-MH battery has high energy density, good low temperature performance, no memory effect, strong overcharge resistance, safety and no pollution, etc. Many advantages, as a sealed battery, the overall weight of the nickel-hydrogen battery is very low, and the number of charge and discharge is about two to three times that of a lead-acid battery. However, nickel-metal hydride batteries have poor high temperature resistance and low working voltage. The overall price is higher than that of lead-acid batteries and lithium-ion batteries. The overall performance is worse than that of lithium-ion batteries. The overall use of technology needs to be further improved. Therefore, there are still relatively few companies in the market that use nickel-hydrogen storage batteries as batteries for electric vehicles. The fourth type of nickel-metal hydride batteries: nickel-cadmium batteries. Nickel-cadmium batteries are relatively rare as electric vehicle batteries. Although both nickel-cadmium batteries and nickel-hydrogen batteries are alkaline batteries, nickel-cadmium batteries are due to memory effect and heavy metal content. Higher factors have been gradually eliminated from the market, so I won’t give a detailed introduction here.
