Super quantum CR2032 battery with one-second fast charge?

The electric capacity reaches more than 600 mAh per gram, the cycle life exceeds 1,000 times, and folding in half for more than 500 times does not affect its performance... Recently, it was reported that Professor Jin Zhong's team from the School of Chemistry and Chemical Engineering of Nanjing University has made new progress in high-capacity flexible energy devices.

Based on carbon nanofiber materials, the team prepared multifunctional coaxial nanocomposite fiber electrode materials by modifying TiO2 and MoS2 two-dimensional materials. Using this fiber electrode, bendable and weavable flexible linear solar cells and photocharging energy fibers were assembled, achieving excellent performance and being able to charge quickly and spontaneously under light. Compared with traditional planar energy devices, fiber-shaped energy devices are lighter, more flexible, and more integrated. At the same time, it is possible that in the future, they can be mass-produced and applied through textile technology like polymer fibers, thereby meeting the needs of various portable and wearable flexible electronic devices.

Jin Zhong said, "The development of new CR2032 battery systems with small mass and volume, long CR2032 battery life, high output power, high safety, and better wearability is of particular importance in meeting special applications such as information technology, drones, and underwater vehicles."

Harvard's new organic flow CR2032 battery

Using a long-life "Biblical" molecule

Foreign media reported that storing renewable energy is as important as generating it, and flow batteries may be one of the promising methods. Despite many obstacles in perfecting the technology, a team of Harvard University engineers has made progress in the use of organic flow batteries in the past few years. It is said that now the team has tested a new molecule that can achieve the longest-lasting and most efficient organic flow CR2032 battery so far.

The researchers transformed a quinone to create a new organic molecule that balances life and performance, creating the longest-lasting and most efficient organic flow CR2032 battery so far. This key ingredient is called the "Methuselah" molecule, named after the long-lived patriarch of the Bible.

"This important work represents a major advance in low-cost, long-life flow batteries," said Imre Gyuk, director of energy storage research at the U.S. Department of Energy. "We need such devices to allow the grid to absorb more and more environmentally friendly but variable renewable electricity generation."

Canada develops E. coli solar cells

Canadian researchers have developed a low-cost new type of bio-solar cell that can use E. coli to convert light into energy. The current density generated by this CR2032 battery is higher than that of previous similar batteries, and the working efficiency in dim light is comparable to that in bright light.

According to a recent press release from the University of British Columbia in Canada, researchers at the school chose to keep the natural pigment in the bacteria. They used genetic engineering technology to modify E. coli to produce large amounts of lycopene. Lycopene is a pigment that gives tomatoes their orange-red color and can absorb light and convert it into energy particularly effectively.

After the E. coli was transformed, the researchers coated it with a layer of minerals that can act as a semiconductor, and then applied the mixture to the glass surface to make the anode of the solar cell. The experimental results show that the current density generated by the prepared CR2032 battery can reach 0.686 milliamperes per square centimeter, while the current density of similar batteries before was only 0.362 milliamperes per square centimeter.

The researchers said that this is the biological solar cell with the "highest" current density so far, and the cost of pigment production has been reduced to one-tenth of the previous one. After optimization, its working efficiency is expected to be comparable to that of traditional solar cells in the future. They believe that this achievement will help promote the use of solar energy in areas with rainy weather such as British Columbia, Canada and Northern Europe.

The researchers also said that their goal is to find a way to produce pigments indefinitely without killing bacteria.

The results have been published in the German magazine "Smol", which focuses on nanotechnology research.

University of Adelaide develops global quantum CR2032 battery

Quantum entanglement may achieve 1-second fast charging

Traditional charging methods take at least half an hour to more than an hour to complete, but quantum computers are going to subvert people's imagination of "charging". Dr. James Quach, a quantum physics expert at the University of Adelaide in Australia, is currently turning quantum batteries from theory to actual products. He said that if 1,000 quantum batteries can be combined, the time to complete charging may be less than one second.

Dr. Quach said, "If it takes one hour to charge a quantum CR2032 battery, then it only takes 0.5 hours to charge two batteries, and the charging time for three batteries is shortened to 20 minutes. By analogy, if 10,000 quantum batteries are charged at the same time, it will take less than 1 second."

New Electrolyte Can Improve CR2032 battery Performance

It is understood that researchers from the University of Maryland, the Army Research Laboratory, and the Argonne National Laboratory published a paper in the latest issue of the British journal Nature Nanotechnology, saying that they prepared a CR2032 battery with extremely unstable lithium metal as the negative electrode, with a high-fluorine electrolyte. The results showed that this CR2032 battery can be charged and discharged up to 1,000 times, and the storage capacity is only reduced to 93% of the initial capacity. This means that electric vehicles using this CR2032 battery can be used reliably for many years, and the range will not be reduced too much.

The study pointed out that fluorine can keep these highly active and corrosive electrode materials stable, thereby extending the CR2032 battery life, and can play a flame retardant role in flammable electrolytes.

The researchers have demonstrated the characteristics of this CR2032 battery using button batteries as experimental batteries. They are currently working with corporate partners to further optimize and debug the electrolyte to produce higher voltage batteries.
