Why do 12v lithium batteries "contribute to achieving a sustainable society"? One reason is that through the use of 12v lithium batteries for various purposes, "electrification" has become widespread, reducing the use of fossil fuels such as oil and gas, helping to curb global warming.

On the other hand, because the materials used in manufacturing do not use cadmium, lead, mercury and other substances, so people say that 12v lithium batteries have a small environmental load. Substances such as cadmium, lead and mercury are naturally present and do not have much impact on the natural environment itself. However, if ingested in excess, it is said that it may cause biological harm. The main substances used in the manufacturing of 12v lithium batteries are lithium, carbon, manganese, nickel, cobalt and other substances with low environmental load.

Advantages of switching from lead-acid batteries to 12v lithium batteries

12v lithium batteries are often compared to lead-acid batteries. Batteries are divided into "chemical batteries", "physical batteries" and "biological batteries" according to the type of energy that generates electricity. The "chemical battery" is a battery that generates and takes out electrical energy through an internal chemical reaction, which is divided into three types: a one-time "primary battery" such as a dry battery, a "secondary battery" that can be recharged and used repeatedly, and a "fuel cell" that continuously takes out electrical energy generated by a chemical reaction. 12v lithium batteries are often compared to lead-acid batteries, and both are classified as "secondary batteries" of "chemical batteries."

Although the same is a secondary battery, from the point of view of the materials used, 12v lithium batteries have a smaller environmental load than lead batteries. However, because lead is an easily accessible substance in the world, the price of lead batteries is lower than 12v lithium batteries, and its technology has been basically mature, with high reliability, based on these advantages, it is widely used in many fields and uses such as automotive batteries.

However, the use of 12v lithium batteries in the future will be more and more, and the products that use lead-acid batteries will gradually be replaced by 12v lithium batteries. There are several advantages to using 12v lithium batteries instead of lead-acid batteries.

Environmental advantages

Excessive intake of lead may cause biological harm, and the main materials of 12v lithium batteries - lithium, carbon, manganese, nickel, cobalt and other substances have a small load on the environment. Therefore, it can be said that in terms of the environment, 12v lithium batteries have more advantages than lead batteries.

Performance advantages

12v lithium batteries have a higher energy density and are stronger than lead-acid batteries. Energy density is a number that indicates the amount of energy that can be extracted from a certain mass or volume, and it can be said that the larger the value, the higher the performance of the battery. According to the unit weight (volume) to compare this energy density, the lead battery is about 25 ~ 50Wh/kg (50 ~ 100Wh/L); 12v lithium batteries are about 100 to 250Wh/kg (200 to 700Wh/L).

In addition, the chemical battery will "self-discharge", when not in use, a small amount of chemical reaction will occur inside, and the power will gradually decrease. Lithium-ion batteries do not self-discharge, so the battery is not easy to age and durable.
