This review systematically presents the recent advancements in Pt-based HER electrocatalysts, emphasizing mechanistic insights across the Volmer, Heyrovsky, and Tafel steps, and explores the influence of Pt’s electronic structure and nanostructuring on HER kinetics. Strategies such as alloying with transition metals (e.g., Ni, Co, Zn), developing single-atom catalysts (SACs), and engineering hybrid systems with supports like MXenes, graphene aerogels, and metal carbides are discussed in detail. These approaches optimize active site exposure, electronic modulation, and catalyst-support interactions to achieve high turnover frequencies, low overpotentials, and enhanced electrochemical stability under industrially relevant conditions. The review further highlights key performance indicators such as Tafel slope, mass activity, TOF, and stability, along with advanced synthesis methods, including atomic layer deposition and microwave-assisted reduction. Finally, current challenges in scalability, degradation resistance, and cost-performance trade-offs are evaluated, providing future directions toward sustainable, high-performance HER systems based on Pt.

Simulation results demonstrate that the highest SoC occurs near the charging tab, leading to preferential full-charge in this region. Intriguingly, when charging is interrupted at this stage, the battery enters a self-balancing state: the state of charge SoC near the tab gradually decreases. At the same time, SoC in other regions increases, culminating in a homogeneous SoC across the entire battery. This phenomenon reflects the underlying process of lithium-ion redistribution. Additionally, a larger resistance disparity between cathodic and anodic current collectors creates an inhomogeneous current density distribution, thereby accelerating localized battery aging.
