Comprehensive “Upworthy” and “truth theory” reports pointed out that Mya Le Thai, a doctoral student studying at the University of California in 2016, after repeated experiments, accidentally developed a rechargeable battery that can last for 400 years; Relevant research breakthroughs have not yet seen significant progress.


UC PhD student accidentally invents battery that lasts 400 years

According to “Upworthy”, a research team at the University of California, Irvine (UCI) has tried to use nanowires (nanowires) as a material for making batteries; for a complete charge cycle. The researchers then found that the thin and fragile nanowires gradually wore out and eventually broke through multiple cycles of the charging pattern.

One day in 2016, on a whim, Mya Le Thai mixed a gel made of manganese dioxide and plexiglass electrolyte, coated it on gold nanowires, and conducted a charging experiment. After the success, Thai began to recycle. gel capacitor.

The importance of Thai’s research and development in this field lies in breaking through the battery life of traditional rechargeable batteries. Prior to this, the battery used in general notebooks usually has a storage capacity of 300 to 500 charge-discharge cycles, but the nano-battery designed by Thai can withstand 200,000 charge-discharge cycles in just three months. It is still in normal use, greatly prolonging the life of the laptop battery for at least 400 years.

According to “Upworthy” report, Reginald Penner, dean of the Department of Chemistry at the University of California, believes that the vision of this research and development project is to find a simple technology to stabilize the operation of nanowires. If all goes well, it will be able to significantly promote the technological development of society, and it will no longer be just a test in the laboratory.


Environmental Burdens of Battery Raw Material Mining and Discarded Batteries

“AZO cleantech” reported that the widespread use of lithium batteries has also led to a continuous increase in demand in recent years with the popularity of electric vehicles. However, the waste lithium batteries and the original mining process of lithium mines will bring a huge burden to the environment. Lithium batteries contain potentially toxic nickel, copper, and lead materials, and used batteries can be an environmental disaster if mishandled or even risk an explosion if improperly stored.
