In recent years, the development of the industry, whether it is automobiles or motorcycles, can be said to be changing with each passing day, but as a starting battery for various vehicles, it has been stuck in the traditional lead-acid battery. As we all know, the deleaded and sulfuric acid in lead-acid batteries are both highly polluting substances, and the overall energy efficiency of the battery is not high. To improve this problem, sodium-ion starter batteries were finally introduced, providing a better option for starting batteries in vehicles.
According to the respective properties of sodium battery and lead-acid battery, we compared the two, and found that sodium battery can form a [dimensionality reduction attack] on lead-acid battery, as follows:
1.High and low temperature adaptability: Sodium batteries have better adaptability to extreme temperatures than lead-acid batteries. In the cold winter, sodium batteries are able to maintain high energy output and charging efficiency, while the performance of lead-acid batteries will be affected by low temperatures, and the capacity and power output will drop significantly. In contrast, the higher energy density and fast charging characteristics of sodium batteries make them more stable and reliable in low-temperature environments.
2.Cycle life: Sodium batteries have a longer cycle life compared to lead-acid batteries. In the process of use, the battery will continue to undergo the process of charging and discharging, and the sodium battery can maintain a higher capacity retention rate and cycle life in the charging and discharging cycle, and has a high service life. In contrast, lead-acid batteries are prone to capacity loss and polarization during cycling, resulting in a shorter cycle life.
3.High temperature tolerance: In the hot summer months, sodium batteries have better high temperature tolerance than lead-acid batteries. In a high-temperature environment, sodium batteries can maintain high energy output and charging efficiency, while the performance of lead-acid batteries will be affected at high temperatures, and their capacity and power output will decrease.
4.Safety: Sodium batteries have higher safety than lead-acid batteries. Sodium batteries use sodium ions as the charge carrier, and the sodium ions are larger, which makes the battery more stable under extreme conditions such as overcharge, overdischarge, and high temperature. Sodium batteries can also be stored at zero voltage, which is safer, in contrast, lead-acid batteries often have gas generation and liquid leakage when overcharged or overdischarged, increasing the risk of fire and **.
5.Environmental friendliness: Sodium batteries mainly use sodium as the production material. Sodium is a ubiquitous substance, which determines that the battery will not cause pollution and damage to the environment during the production and production process. In contrast, lead is a toxic substance, and sulfuric acid is a highly polluting substance, so the production and disposal of lead-acid batteries may have adverse effects on the environment. Therefore, sodium batteries have obvious advantages in terms of environmental friendliness.
