My scientist has increased the energy density and endurance of lithium batteries by 2-3 times

According to Xinhua News Agency, Tianjin, August 13th (reporters Zhang Jianxin and Li Yating) Recently, Chinese researchers have broken through the bottleneck of traditional lithium-ion batteries in terms of energy density and application performance, and developed soft pack batteries with energy density exceeding 600 watt hours/kg and modular batteries with energy density of 480 watt hours/kg. Their performance indicators are directly 2-3 times higher than the energy density and endurance of existing lithium-ion batteries.

Lithium metal batteries are regarded as a new generation battery technology that solves the performance bottleneck and endurance of existing batteries due to their theoretical energy density far higher than traditional lithium-ion batteries. But currently, its electrolyte design is difficult to simultaneously meet the requirements of battery energy output and cycle life improvement.

After years of technological innovation and breakthroughs, the research team and collaborators at Tianjin University have pioneered the "delocalization" design concept for high-energy metal lithium battery electrolytes, breaking the traditional electrolyte design's reliance on dominant solvation structures and achieving a dual improvement in energy density and comprehensive performance. The related research results were published in the international academic journal Nature on August 13th.
