Electric vehicle lithium battery and lead-acid battery which is better
Advantages and disadvantages of lead-acid batteries
High cost performance It is generally believed that lead-acid batteries for electric vehicles are better than lithium batteries, mainly because lead-acid batteries are safer, relatively cheap, and easier for the public to use.
Accepted, the most important thing is that the recycling price of lead-acid batteries is higher than that of lithium batteries.
| High rate discharge performance is better. Generally speaking, a set of lead-acid batteries only costs a few hundred yuan, and a set of lithium batteries costs more than one thousand or nearly two thousand yuan. lead
Acid batteries have strong overload capacity and impact resistance. The resistance of electric vehicles changes at any time, or even stops suddenly. At this time, the battery current changes greatly.
Yes, in the few seconds when the ignition is on, the current reaches two to three hundred amperes, and the lead-acid battery can be safe and sound, while the lithium battery is hard to come by.
Lead-acid batteries also have disadvantages such as heavy metals are easy to cause environmental pollution; compared with lithium batteries, lead-acid batteries have lower energy density; and their service life is not as good as lithium batteries.
Advantages and disadvantages of lithium batteries
High energy efficiency Lithium-ion batteries have more than 3 times higher energy than lead-acid batteries in terms of volume specific energy and gravimetric specific energy. Lithium batteries are smaller, lighter, and have a longer cycle life.
Lightweight and environmentally friendly lithium batteries are relatively lightweight, easy to carry, and have a much longer lifespan. In addition, lithium batteries are more adaptable to high and low temperatures, are less affected by temperature factors, and are more environmentally friendly.
Lithium batteries also have three disadvantages. The safety and stability are relatively poor. If they are not handled properly, there is a risk of explosion. In addition, lithium batteries do not
It can be discharged with a large current and has high production requirements and higher costs.
summary
At present, the market penetration rate of lithium electric vehicles is lower than that of lead-acid battery vehicles. The main factor is that the technology is not perfect, and the cost of lithium batteries is still relatively high. therefore
In the existing "lithium electric vehicle" product design, the capacity configuration of lithium batteries is mostly used to reduce the implementation cost of the whole vehicle, which makes the existing lithium electric vehicle "production
The models of products are too single. For example, most lithium battery products currently on the market are "motorcycles with a short range, but like four-wheeled electric vehicles,
Four-wheeled elderly electric scooters, which are relatively long-range, are more suitable for lead-acid batteries in the current situation.” In short, which is better, lead-acid batteries or lithium batteries, cannot be judged simply by the quality of the batteries, and both have their own advantages. Inferior, should be suitable for different demand groups, consumers should choose according to their own needs.
