Which is better, lead acid battery or lithium battery for electric vehicle?
Lithium battery is better than lead acid battery.
1. Battery life
Lead-acid batteries generally have a short lifespan, while lithium batteries can be used for longer. Additionally, lithium battery life is limited by the number of charges, and overcharging or overdischarging can shorten its life.
2. Energy density
Lithium batteries have a higher energy density, which means they can store more energy in a smaller space. This makes lithium batteries the preferred battery type for electric vehicles, which require higher energy density.
3. Cost
Lead-acid batteries are cheaper than lithium batteries, making them an option for electric vehicleson a low budget. However, the price of lithium batteries is gradually decreasing, so they are becoming more and more popular.
4. Durability
Lithium batteries are more environmentally friendly than lead-acid batteries because they do not contain harmful substances. Additionally, lithium batteries can be recycled, making them more durable than lead-acid batteries.
Which electric vehicle has the longest range between a lithium battery and a lead acid battery?
Battery vehiclesLead acid batteries, lithium batteries.
1. Lead Acid Battery: The lifespan of a lead acid battery is generally defined based on the capacity of the battery decreasing to 30% of its original capacity. charged and discharged about 300 times, which takes about a year and a half. Of course, if your driving distance is short, a few kilometers, you can ridefor about three years.
2. Lithium batteries have strict charge times, usually around 1,000 to 1,200 times, and can be used for 3 to 5 years. Charging lithium batteries is completely opposite to that of lead acid batteries. They must be recharged once exhausted. If the battery is not used for a long time, it should be fully charged every two months to avoid battery protection. extend battery life.
Although lithium batteries have many advantages, their disadvantages are also more obvious:
1. The production cost of lithium batteries is high and the production equipment is high. and labor costs account for about 40% of the production cost, and the price is about three times that of lead-acid batteries. At three times the price, the quality/price ratio is not high, and thisIt seems rather flashy. Additionally, lithium batteries are not recyclable. Once worn out, they can only be thrown away or buried after thousands of years. future generations will dig them up. It's an antique when it comes out.
2. The most important problem is that lithium batteries pose fire and explosion hazards, especially when consumers are unknowingly deceived by profiteers into purchasing substandard, sealed lithium batteries in electric vehicles. The conditions are not very good. , and the world may no longer be the same.
If you compare batteries with the same voltage and capacity, the lead acid battery may have a slightly longer runtime. But the lifespan of lithium batteries will be longer. Lead acid batteries are generally used for more than two years and the battery capacity dimwill increase considerably. The capacity of lithium batteries slowly decreases a little and can be used for a longer period of time.
1. Disadvantages of lead-acid batteries:
Heavy weight, limited battery capacity and short lifespan. Lead-acid batteries typically last two years after 400 deep charges. deep discharges approx.
2. Disadvantages of lithium batteries:
The production cost of lithium batteries is high, the production equipment is expensive, and labor costs account for about 40% of production costs. the price is about three times that of lead-acid batteries. At the same time, lithium batteries are not recyclable and can only be thrown away when they are worn out. Another important problem is that lithium batteries pose potential fire and explosion hazards, especially when consumers are unaware.ent deceived by profiteers and buy poor quality lithium batteries. In electric vehicles, the sealing conditions are not very good and can easily cause damage. Humidity. Poor contact and other reasons may cause safety hazards.
