A team of researchers from Institute of Physics, Chinese Academy of Sciences announced that it has developed a record-breaking 711 Wh/kg (Watt hours per kilogram) rechargeable lithium battery.
The previous record was by a research team at Dalhousie University in Canada, who created a 575 Wh/kg anode-free pouch cell. just last year. Researchers from the Chinese Academy of Sciences tested the battery at 711.3 Wh/kg and had a volumetric “energy density” of 1,653.65 Wh/liter, making it the highest energy density lithium battery on record.
By the way, Tesla’s new 4680 cell has an energy density of 272-296 Wh/kg. this team (via) new atlas) manufactured battery cells with nearly double the energy density. That means you get more power with a much lighter weight. However, there are a number of challenges that need to be overcome before these types of batteries can find their way into gaming laptops.
The researchers gave no indication of what energy output could be obtained from the rechargeable battery, how quickly it would degrade, or what thermal problems would arise. The research team acknowledged that much needs to be done to solve issues such as “battery safety and longevity” and that battery technology is far from “practical.”
The rechargeable 10Ah pouch prototype cell “requires extremely sophisticated process techniques such as highly loaded electrode preparation and lean electrolyte injection,” which is currently too costly to reproduce commercially. New Atlas points out that it does.
Nevertheless, the researchers said in their paper, this ultra-high energy density battery technology is China’s “imperative for high-performance power technology in special application scenarios such as high altitude and deep space, as well as future electric aircraft.” can meet the needs of field. ”
Regardless of the industry, the demand for smaller, denser batteries is high, and it will be interesting to see how far the limits of lithium batteries can be pushed until new power sources like Element Zero of Mass are found. effect. I want my gaming laptop to last an hour or more when not plugged in, so I use whatever I can get.
