Core Viewpoint - Tsinghua University's latest research on solid-state batteries demonstrates a significant advancement in energy density, achieving up to 604Wh/kg and 1027Wh/L, nearly doubling the energy density of current commercial lithium-ion batteries [2][5][9]. Group 1: Research Breakthrough - The core innovation lies in a new "in-situ construction" strategy for a fluorinated polyether-based polymer electrolyte (FPE-SPE), which addresses the interface instability issues of high-capacity lithium-rich manganese oxide (LRMO) cathodes [6][8]. - The research has been published in the prestigious journal "Nature," indicating its scientific significance [2][5]. Group 2: Energy Density and Safety - The new battery design features a high-capacity LRMO cathode, a lean electrolyte design, and a no-anode structure, contributing to its high energy density [9][11]. - The FPE-SPE battery exhibits excellent long-term stability, maintaining 72.1% capacity after 500 cycles at 0.5C, compared to only 80% capacity retention after 50 cycles for traditional electrolytes [11]. - The thermal stability of the new battery is significantly improved, with a heat onset temperature of 85.4°C, compared to 33.5°C for liquid electrolytes, and a thermal runaway trigger temperature of 216.0°C, compared to 122.6°C for liquid electrolytes [12]. Group 3: Expert Leadership - The research is led by Professor Zhang Qiang, a distinguished figure in battery materials chemistry, who has received multiple prestigious awards and recognitions for his contributions to energy storage [13][15]. Group 4: Conclusion on Solid-State Battery Production - This research represents a significant step towards the commercialization of solid-state batteries, providing a clear technological pathway and challenging the notion that lithium-ion technology has reached its performance limits [16].
