Is a battery car battery better, a lithium battery or a lead acid battery?

Introduction Is car battery better, lithium battery or lead acid battery? Is car battery better, lithium battery? Lithium batteries have a higher energy density, allowing electric vehicles to have greater endurance and lighter weight.

Is a battery car battery better, a lithium battery or a lead acid battery?

Car batteries are lithium batteries. Lithium batteries have a higher energy density, which allows electric vehicles to have a higher range and lighter weight. Lithium batteries charge faster and get users back on the road faster. Finally, lithium batteries have a longer lifespan than lead-acid batteries, hence lithium. batteries require less maintenance and fewer replacements. Lithium batteries are a more environmentally friendly option because they use fewer materials and can be recycled and reused. Lithium batteries work by moving lithium ions from the cathode to the anode. This process releases energy when the battery discharges, lithium ions move from the cathode to the anode, which provides an electric current. the electric current reverses, the lithium ions returnflow from the anode to the cathode.

Hello, car batteries do not use lithium batteries for the following reasons:

1. Lead-acid batteries are safer and more stable than lithium-ion batteries which discharge at high temperatures. It is easy to form lithium crystals on the negative electrode, which may pierce the separator and cause the battery to short circuit and explode. The particularity of automobiles makes the selection of batteries with high safety and stability the first consideration. Since lead-acid batteries are resistant to low temperatures, the discharge performance of lithium-ion batteries is attenuated at low temperatures. They will run out quickly at minus 10 degrees Celsius. Lead-acid batteries can start a car at minus 50 degrees. Celsius. This is difficult to achieve with lithium batteries.

2. Since the battery usesa lead-calcium alloy as the grid, the amount of water decomposed during charging is small, and the amount of water evaporation is also small. In addition, the case adopts a sealed structure. , and the sulfuric acid gas released is also very small, so compared with traditional batteries, it has the advantage of no need to add liquid. Rated battery life is 27 months. Generally, family cars are relatively economical. Many new car batteries last 3 to 4 years. However, after replacement, they generally need to be replaced after about 2 years. Taxis are relatively expensive and a single bus lasts around a year, while a double bus lasts around 8-10 months. Several factors that affect battery life are: vehicle condition, road conditions and driver habits. The newer the car, the more battery it saves, because the engine is easy to operate, saves battery power, the generator is easy to operate, and the battery can be fully charged when the car gets old, especially after the two large engines. and generators are replaced, due to the differences between these two products on the market. There is a huge price difference between original products and refurbished products, so it is easy for car owners not to replace the original parts, and then the battery will be more likely to break.

3. Cost. The price of conventional lithium batteries is 2-3 times higher than that of lead-acid batteries. Therefore, under the business requirement of "maximizing profits" and without external motivation such as market or law, automobile manufacturers have no motivation to replace lead-acid batteries. with lithium batteries.

4. Technology. As soon as they are marketed, Li batteriesthium first entered the digital domain, then gradually entered the areas of energy applications such as electric vehicles. Starting a car requires relatively high battery performance, which must be provided by a high-rate lithium-ion battery. Lithium batteries themselves also have a technological maturity process, and power batteries have also matured in recent years.
