Will water-based zinc batteries replace lithium batteries?

Researchers at the University of Maryland's research team, the army research laboratory and the National Institute of standards and technology have combined traditional zinc and water battery technologies to develop more powerful and safer rechargeable batteries.

American researchers have developed a rechargeable water-based zinc battery that is not only large in capacity, long in life, but also safer and is expected to be an ideal replacement for lithium batteries that are widely used today.

For batteries, small size, large capacity, long life, high safety, and low manufacturing cost are all ideal quality requirements, but batteries with these characteristics are still difficult to find. Take lithium batteries, which are widely used in consumer electronics, although they are remarkable in terms of capacity, volume, and longevity, the risk of the explosion has caused many people to fall ill.

The research team of the University of Maryland, the Army Research Laboratory and the National Institute of Standards and Technology researchers combined traditional zinc battery technology with water battery technology to develop a larger capacity and higher safety. rechargeable battery. They use a new type of aqueous electrolyte to replace the flammable organic electrolyte used in traditional lithium-ion batteries, which greatly improves the safety of the battery. By adding metal zinc and adding salt to the electrolyte, the energy density of the battery is effectively improved.

The researchers pointed out that zinc batteries are a safe and relatively low-cost battery, but the energy density is low and life is short, so it is not perfect. The new water-based zinc battery overcomes these shortcomings of traditional zinc batteries, which not only greatly increases the energy density of the battery, but also extends the battery life. Compared with lithium batteries, water-based zinc batteries are not only superior in terms of energy density but also much safer, without the risk of explosion or fire.

Researchers are confident about the commercialization of new water-based zinc batteries. They say that the new battery will eventually be used not only in consumer electronics but also as a strong competitor for lithium batteries. It can also be used in extreme environments such as space and deep sea, and it can be used inspecial, deep-sea exploration and military fields.
