With large capacity and long life, water-based zinc CR2430 batteryhave the opportunity to become a substitute for lithium batteries

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

　　For batteries, small size, large capacity, long life, high safety, and low manufacturing cost are all ideal quality requirements, but CR2430 batterythat combine these characteristics are currently difficult to find. Take lithium batteries, which are widely used in consumer electronics products. Although they are remarkable in terms of capacity, volume, and lifespan, 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 battery with larger capacity and higher safety. rechargeable battery. They used a new type of aqueous electrolyte to replace the flammable organic electrolyte used in traditional lithium-ion batteries, which greatly improved the safety of the battery. By adding metallic zinc and adding salt to the electrolyte, the energy density of the battery was effectively increased.

　　The researchers note that zinc CR2430 batteryare safe and relatively cheap to produce, but they have low energy density and short lifespan, making them imperfect. 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 CR2430 batterynot only compete with them in terms of energy density, but are also much safer, without the risk of explosion or fire.

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