Electrochemical energy storage is becoming essential for portable electronics, electrified transportation, integration of intermittent renewable energy into grids, and many other energy or power applications. The electrode materials and their structures, in addition to the electrolytes, play key roles in supporting a multitude of coupled physicochemical processes that include electronic, ionic, and diffusive transport in electrode and electrolyte phases, electrochemical reactions and material phase changes, as well as mechanical and thermal stresses, thus determining the storage energy density and power density, conversion efficiency, performance lifetime, and system cost and safety. Different material chemistries and multiscale porous structures are being investigated for high performance and low cost. The aim of this Special Issue is to report the recent advances of materials used in electrochemical energy storage that encompasses supercapacitors and rechargeable batteries.
电化学储能对于便携式电子产品、电动交通工具、间歇性可再生能源并入电网以及许多其他能源或电力应用而言正变得至关重要。除电解质外，电极材料及其结构在支持众多耦合的物理化学过程中发挥着关键作用，这些过程包括电极和电解质相中的电子、离子和扩散传输、电化学反应和材料相变，以及机械和热应力，从而决定了储能密度和功率密度、转换效率、性能寿命以及系统成本和安全性。人们正在研究不同的材料化学和多尺度多孔结构以实现高性能和低成本。本期特刊的目的是报道用于电化学储能的材料（包括超级电容器和可充电电池）的最新进展。
