The advancement of electrochemical energy storage (EES) technologies is critical to meeting increasing demands for high energy capacity, superior power output, and extended cycle life. Despite significant progress, most existing EES systems remain unsuitable for large-scale commercialization due to performance and design limitations. This review uniquely bridges the gap between material engineering and device-level optimization by critically examining how innovations in electrode materials, electrolyte systems, and interface design translate into enhanced electrochemical performance at the device scale. Special attention is given to the emerging class of supercapattery known as hybrid devices that synergistically integrate the rapid charge-discharge characteristics of supercapacitors with the high energy density of battery. By elucidating the interplay between Faradaic and non-Faradaic processes, the review demonstrates how tailored material properties and structural engineering can be leveraged to optimize device architectures for improved energy and power densities, cycling stability, and charge retention. These insights offer a comprehensive perspective on the design of next-generation energy storage systems and support future research and commercialization strategies for high-performance supercapatteries. © 2026 Elsevier Ltd.
