高能量密度与高功率密度兼顾型锂离子电池研究现状与展望

Lithium-ion batteries have become the most widely used energy storage devices, with energy density and power density as critical parameters for assessing their performance. However, high energy density and high-power density represent a contradictory pair, exhibiting a "trade-off" phenomenon. The development of lithium-ion batteries with both high energy density and high-power density (referred to as "dual-high" lithium-ion batteries) is crucial for addressing the demands of high-efficiency modern equipment (such as special equipment, electric drones, etc.). Essential new materials are the primary factors determining the performance of dual-high lithium-ion batteries, and the advancement in battery performance requires a focus on energy storage mechanisms and innovative material preparation technologies. This paper first introduces the definition and key performance indicators of dual-high lithium-ion batteries and subsequently reviews the recent advancements in critical cathode and anode materials for dual-high lithium-ion batteries and their modification strategies. It also evaluates the influence of various electrolytes on the performance of lithium-ion batteries and discusses the design and fabrication of dual-high lithium-ion batteries. A summary of the current research status, challenges, and future development trends is presented, offering innovative concepts for designing and developing the next generation of dual-high lithium-ion batteries.
