Sulfur-based batteries, known for their low cost and high capacity, are promising next-generation battery systems. However, their development is limited by complex conversion reaction mechanisms and significant capacity fading.

With long-standing expertise in sulfur-based battery technology, Quanquan has conducted innovative research across all configurations of sulfur-based batteries, including electrode material design, electrolyte development, and the evolution and engineering of interphases.

He proposed a molten salt aluminum-sulfur battery that uses molten salt electrolytes, which offer high thermal stability and intrinsic non-flammability. It can be charged within tens of seconds, expected to cost only 1/5-1/6 of current commercial lithium-ion batteries ,and support a wide range of charge/discharge rates. By effectively addressing the safety challenges of large-scale energy storage systems, it shows strong potential for grid-scale frequency regulation, wind and solar energy storage, and industrial/commercial applications.

Recently, Quanquan also developed a novel iodine-containing glassy sulfide electrolyte. As an ion conductor within the sulfur electrodes, it also enables fast solid-solid sulfur reactions through a rapid iodine redox mediation mechanism.

The resulting all-solid-state lithium-sulfur battery charges in minutes and lasts for tens of thousands of cycles. When used in new energy vehicles, it is expected to support a lifespan of 30 to 40 years. With its low cost, high safety, and exceptional longevity, this technology has strong industrialization prospects and may become a next-generation power battery, accelerating the global transition to electric vehicles.
