Despite their inherent advantages, these materials encounter significant practical hurdles, including low initial Coulombic efficiency (ICE), diminished cycle/rate performance, and voltage fading during cycling, hindering their widespread adoption. In response, we introduce an ionic-electronic dual-conductive (IEDC) surface control strategy that integrates an electronically conductive graphene framework with an ionically conductive heteroepitaxial spinel Li₄Mn₅O₁₂ layer. Prolonged electrochemical and structural analyses demonstrate that this IEDC heterostructure effectively minimizes polarization, mitigates structural distortion, and enhances electronic/ionic diffusion. Density functional theory calculations highlight an extensive Li⁺ percolation network and lower Li⁺ migration energies at the layered-spinel interface. The designed LLO cathode with IEDC interface engineering (LMOSG) exhibits improved ICE (82.9% at 0.1 C), elevated initial discharge capacity (296.7 mAh g⁻¹ at 0.1 C), exceptional rate capability (176.5 mAh g⁻¹ at 5 C), and outstanding cycle stability (73.7% retention at 5 C after 500 cycles).

Proton exchange membrane (PEM)-based electrocatalytic systems represent a promising technology for hydrogen production, which is equipped to combine efficiently with intermittent electricity from renewable energy sources. In this review, PEM-based electrocatalytic systems for H₂ production are summarized systematically from low to high operating temperature systems. When the operating temperature is below 130°C, the representative device is a PEM water electrolyzer; its core components and respective functions, research status, and design strategies of key materials especially in electrocatalysts are presented and discussed. However, strong acidity, highly oxidative operating conditions, and the sluggish kinetics of the anode reaction of PEM water electrolyzers have limited their further development and shifted our attention to higher operating temperature PEM systems. Increasing the temperature of PEM-based electrocatalytic systems can cause an increase in current density, accelerate reaction kinetics and gas transport and reduce the ohmic value, activation losses, Δ<i>G</i>_H*, and power consumption. Moreover, further increasing the operating temperature (120–300°C) of PEM-based devices endows various hydrogen carriers (e.g., methanol, ethanol, and ammonia) with electrolysis, offering a new opportunity to produce hydrogen using PEM-based electrocatalytic systems.

Nevertheless, inherent challenges in graphene fibers (GFs), particularly the restricted ion-accessible specific surface area (SSA) and sluggish ion transport kinetics, hinder the achievement of optimal capacitance and rate performance. Despite existing reviews on GFSCs, a notable gap exists in thoroughly exploring the kinetics governing the energy storage process in GFSCs. This review aims to address this gap by thoroughly analyzing the energy storage mechanism, fabrication methodologies, property manipulation, and wearable applications of GFSCs. Through theoretical analysis of the energy storage process, specific parameters in advanced GF fabrication methodologies are carefully summarized, which can be used to modulate nano/micro-structures, thereby enhancing energy storage kinetics. In particular, enhanced ion storage is realized by creating more ion-accessible SSA and introducing extra-capacitive components, while accelerated ion transport is achieved by shortening the transport channel length and improving the accessibility of electrolyte ions. Building on the established structure–property relationship, several critical strategies for constructing optimal surface and structure profiles of GF electrodes are summarized.
