3.7v 3000mah 18650 battery

The United States has developed a product that may replace 3.7v 3000mah 18650 battery

American researchers have developed a rechargeable water-based zinc battery that not only has a large capacity and long life, but is also safer and is expected to become an ideal substitute for the widely used lithium batteries.

For batteries, small size, large capacity, long life, high safety, and low manufacturing cost are all ideal quality requirements, but batteries that combine these characteristics are still difficult to find. Take the lithium batteries widely used in consumer electronics as an example. Although they are remarkable in terms of capacity, volume, and life, their explosion risk has been criticized by many people.

This time, a research team composed of researchers from the University of Maryland, the Army Research Laboratory, and the National Institute of Standards and Technology combined traditional zinc battery technology with water battery technology to develop a rechargeable battery with larger capacity and higher safety. They used a new type of aqueous electrolyte to replace the flammable organic electrolyte used in traditional 3.7v 3000mah 18650 battery, which greatly improved the safety of the battery; and by adding metallic zinc and adding salt to the electrolyte, the energy density of the battery was effectively increased.

The researchers pointed out that zinc batteries are safe and relatively low-cost batteries, but they have low energy density and short life, so they are not perfect. The new water-based zinc battery overcomes these shortcomings of traditional zinc batteries, not only greatly improving the energy density of the battery, but also extending the battery life. Compared with lithium batteries, water-based zinc batteries can not only compete with them in terms of energy density, but are also much safer and will not have the risk of explosion or fire.

Researchers are confident about the commercial prospects of the new water-based zinc battery. They said that the new battery will eventually not only be used in consumer electronics and become a strong competitor to lithium batteries, but also can be used in extreme environments such as space and deep sea, and will be useful in special aerospace, deep sea exploration and special fields.
