摘要:

锂离子电池已成为当前应用最广泛的储能器件,能量密度、功率密度是评价其性能的两个重要参数。然而,高能量密度与高功率密度存在矛盾,有着“此消彼长”的现象。发展高能量密度和高功率密度兼顾型锂离子电池(简称双高型锂离子电池)对于进一步满足高效能、现代化装备(如特种装备、电动无人机等)具有重要意义。关键新材料是决定双高型锂离子电池性能的基本和核心因素,电池性能的跃升需要从储能机制、新材料制备技术出发。本文首先介绍了双高型锂离子电池的定义及关键性能指标,随后综述了双高型锂离子电池关键正极、负极材料及其改性策略等方面的研究进展,以及不同类型的电解质对锂离子电池性能的影响,并对双高型锂离子电池的设计和研发进行了讨论,总结了研究现状、面临的挑战和未来发展趋势,为下一代双高型锂离子电池的设计开发提供了新思路。

Abstract:

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.

Key words: dual-high lithium-ion batteries, high energy density, high power density, high-capacity and high-rate electrode materials, high-voltage and high-conductivity electrolytes, battery design
