Chinese scientists have made a new breakthrough in the field of all-solid-state lithium batteries, which is expected to facilitate the miniaturization and long endurance of electronic devices. The research team has developed a homogenized cathode material (lithium titanium germanium phosphorus sulfur selenium) that boasts high conductivity, high energy density, and long service life. This achievement was published in Nature Energy on July 31. This research provides support for the development of energy storage devices with high energy density and long service life, offering safe and durable power sources for new energy vehicles, energy storage grids, and deep-sea and deep-space equipment. It holds great significance for the development of new energy storage systems.
