402030 battery

　　Water-based zinc batteries replace 402030 battery? Technological breakthrough or gimmick?

　　After developing a water-based lithium battery last year, the University of Maryland in the United States has developed a water-based zinc battery. Can it be commercialized this time?

　　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 batteries that 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 402030 battery, 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 batteries are 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 batteries not 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.

　　Relevant research results were published in the latest issue of the journal Nature Materials.

　　In fact, as early as September last year, researchers from the U.S. Army Research Laboratory (ARL) and the University of Maryland developed for the first time a lithium-ion battery that uses a water-salt solution as an electrolyte, which can achieve the required battery life for home electronic devices such as laptops. 4.0 volts and does not pose the fire and explosion hazard associated with some commercially available non-aqueous 402030 battery.

　　According to Dr. Kang Xu, an ARL researcher specializing in electrochemistry and materials science and lead author of the study, this technology will provide soldiers with a completely safe and flexible lithium-ion battery with the same energy as SOA 402030 battery. density. There is no risk of fire or explosion even under severe mechanical abuse.

　　Comment: Water-based batteries have a significant effect in improving battery safety. From solid-state batteries to graphene batteries and now water-based zinc batteries, new battery concepts are always emerging, but so far, in actual applications , no battery can truly achieve breakthroughs and achieve industrialization. You can pay attention to new battery technologies, but these so-called new technologies are more of a hype concept. What the industry should pay more attention to is whether the new technologies have the conditions for industrialization in the near future.
