The impact of new developments in lithium battery technology on its service life

In the lithium battery industry, we often see the news of successful testing of new materials in Korea and Japan. It seems that China's research in the battery field is “obstructed”. In fact, Chinese battery researchers have never given up their efforts to explore, and recently, some of their achievements have also attracted the attention of the global battery industry.

The research team from the National Laboratory of Condensed Matter Physics, Institute of Physics, Chinese Academy of Sciences, proposed a new concept to delay the formation of lithium dendrites in high-capacity lithium batteries. In lithium-ion batteries, "lithium dendrites" due to uneven precipitation are the main cause of reduced cycle life of batteries. They describe the capture of lithium ions in hollow silica microspheres with carbon nanotube cores to inhibit lithium formation of dendrites.

Simply put, a new way to capture lithium ions in the battery allows the battery anode to maintain 99% ultra-high plating efficiency and stripping efficiency in 200 cycles. If the technology is mature, it cannot make the current power battery have more capacity, but it can effectively extend the battery life and suppress the attenuation. Maybe in the future, our car power battery can also be "lasting."
