Endurance Increased Multiple Times: Chinese Scientists Achieve Pioneering Breakthrough in Core Lithium Battery Technology

Recently, Chinese scientists have achieved a new breakthrough in core lithium battery technology. A research team composed of units such as Nankai University and the Shanghai Institute of Space Power Sources has developed a novel electrolyte technology that is expected to significantly enhance the endurance of existing lithium batteries, while also notably improving their low-temperature performance. This achievement was published in the international academic journal *Nature* on the 26th.

This blue lithium battery is a conventional product currently in use, while the thin, silver-gray sample represents the new technological achievement of the Nankai research team. Although their energy levels are similar, the latter is significantly smaller in size. This means that if manufactured with the same volume and weight, the new battery’s endurance could be greatly improved.

The core breakthrough of the new battery lies in its internal electrolyte, which functions as a medium for ion conduction, much like a “highway” between the positive and negative electrodes. Currently, the electrolyte solvents in lithium-ion batteries typically contain an important element—oxygen. Its advantage lies in its strong ability to dissolve lithium salts, but this strong interaction also limits charge transfer, making it difficult to further increase the battery’s energy density and restricting its low-temperature performance.
