Liu''s group proposed a fast and precise ML approach to predict the binding energy of lithium polysulfides (LiPS, Li 2 S 4, Li 2 S 6, and Li 2 S 8) on host materials (MoSe 2 /WSe 2) with arbitrary configurations and random sites (Figure 6D). 156 They first computed single-point binding energy by DFT, and acquired a dataset of thousands of …
The energy barrier of pristine Li 2 S is as high as 3.4 eV per chemical formula, while the energy barrier of Li 2 S@NC:SAFe is merely 0.81 eV (Fig. 1 C). The result indicates that the highly active SAFe could dramatically decrease the energy barriers for delithiation of Li 2 S and facilitate the transport of Li ion in the electrode (Table S1).
Electrochemical energy storage technologies have a profound influence on daily life, and their development heavily relies on innovations in materials science. Recently, high-entropy materials have attracted increasing research interest worldwide. In this perspective, we start with the early development of high-entropy materials and the …
Manganese-based flow batteries have attracted increasing interest due to their advantages of low cost and high energy density. However, the sediment (MnO 2) from Mn 3+ disproportionation reaction creates the risk of blocking pipelines, leading to poor stability. Herein, a titanium–manganese single flow battery (TMSFB) with high stability is designed …
Advanced materials play a critical role in enhancing the capacity and extending the cycle life of energy storage devices. High-entropy materials (HEMs) with controlled compositions and simple phase structures have attracted the interest of researchers and have undergone rapid development recently.
2. Emerging electrode materials. In 1957, Becker received the first patent for an electrochemical capacitor based on activated carbon, proposing that electricity could be stored in the double-layer interface between porous carbons with large specific surface area and aqueous electrolytes, which ushered in a new era of electrode material utilization.

Hybrid energy storage (combining two or more energy storage types) is sometimes used, usually when no single energy storage technology can satisfy all …
A more direct strategy to address grain-boundary fracture is using single-crystal (SC) particles so that internal grain boundaries and inter-granular fracture are eliminated (see schematic illustration in Fig. 1) is also possible to achieve higher electrode compact density (>3.8 g cm −3 for NMC electrodes) with the SC particles because they …
Metal hydrides are famous for their unique ability to absorb hydrogen [8], [12] and release it later, either at room temperature or through heating of the tank (Fig. 1).Metal hydrides possess hydrogen storing capacity of 5–7 wt% [41], but only when heated to temperatures of 2500 °C or higher. Metal hydrides tend to bind strongly with hydrogen …
