Lithium-ion batteries have become increasingly essential in emerging electric vehicle and aircraft markets.
As a core component of batteries, cathode material plays a vital role in energy storage and release through chemical reactions during charging and discharging.
Lithium-rich layered oxide cathode materials can boost battery energy density by over 30 percent. However, after repeated charging cycles, the voltage gradually decays, leading to battery aging.
How to extend the lifespan of lithium-ion batteries? Researchers at the Ningbo Institute of Materials Technology and Engineering (NIMTE) of the Chinese Academy of Sciences offered a solution. Click on the video to explore more!

China's first fixed-wing aircraft for Antarctic research has been delivered by a U.S. producer and will be deployed in the country's 32nd scientific expedition to Antarctica. The red-and-white aircraft is printed with the logo of the State Oceanic Administration and "CHINARE", which represents the China national Antarctic and Arctic research expedition.
Electric cars seem to be an ideal option among next-generation automobiles: They are eco-friendly and accelerate fast with less noise, among other benefits. The trouble is that every 300 kilometers you may have to wait hours to refill your batteries at a charging station.
