With the continuous development of new energy application technology, there is an increasingly urgent need for the safety and affordability of new energy storage products. In recent years, aqueous zinc-ion batteries based on mild aqueous electrolytes have garnered widespread attention as a potential replacement for traditional lithium-ion batteries. However, the limited capacity and low operating voltage of aqueous zinc-ion batteries restrict their widespread application. For this reason, sulfuric acid was added to the electrolyte, which effectively promotes the two-electron conversion of MnO2/Mn2+ during the discharge process. This enhancement results in the high-voltage segment of the batteries' discharge phase offering a higher reversible specific capacity. The results showed that the batteries with 0.1 M H2SO4 added to the electrolyte had a reversible discharge specific capacity of up to 536.07 mAh·g-1 at a current density of 100 mA·g-1. The activated batteries exhibited a reversible specific capacity of 85.11 mAh·g-1 even at a high current density of 1 A·g-1. Furthermore, the capacity retention rate after 1,000 cycles was 88.3%. Moreover, the activation rate of the batteries was faster with the addition of H2SO4, and the average operating potential increased compared to the batteries without H2SO4 in the electrolyte. This provides an effective solution for the practical application of aqueous zinc-ion batteries in power grids.

Germanium has been recognized as a promising anode material for lithium-ion batteries (LIBs) due to its high theoretical capacity and excellent lithium-ion diffusivity. Nonetheless, it is challenging to enhance both the high-rate performance and long-term cycling stability simultaneously. This study introduces a novel heterostructure composed of germanium nanosheets integrated with graphene (Ge NSs@Gr). These nanosheets undergo an in situ phase transformation from a hydrogen-terminated multilayer germanium compound termed germanane (GeH) derived via topochemical deintercalation from CaGe 2 . This approach mitigates oxidation and prevents restacking by functionalizing the exfoliated germanane with octadecenoic organic molecules. The resultant germanium nanosheets retain their structural integrity from CaGe 2 and present an exposed, active (111) surface that features an open crystal lattice, facilitating swift lithium-ion migration conducive to lithium storage. The composite material delivers a substantial reversible capacity of 1220 mA h g −1 at a current density of 0.2 C and maintains a capacity of 456 mA h g −1 even at an ultrahigh current density of 10 C over extended cycling. Impressively, a capacity of 316 mA h g −1 remains after 5000 cycles. The exceptional high-rate performance and durable cycling stability underscore the Ge NSs@Gr anode's potential as a highly viable option for LIBs.

Despite extensive investigation, the utilization of sulfur and the cycling stability of lithium−sulfur (Li−S) batteries are significantly impeded by the polysulfide shuttle effect and sluggish sulfur reaction kinetics. In this study, aimed at enhancing the performance of Li−S batteries, we focus on the implementation of single metal atom (Be, Mg, Ca, V, Nb, and Ta)doped TiS 2 monolayers as cathode catalysts. Our findings reveal that Be-TiS 2 , Mg-TiS 2 , and Ca-TiS 2 exhibit superior polysulfide adsorption capabilities and lower values for the rate-determining step in terms of Gibbs free energy. Electronic structure analysis further elucidates that the enhanced anchoring and electrocatalytic activities stem from the upward displacement of the pband center and the narrowing of the gap within the Δd-p-band, respectively. Moreover, Be-TiS 2 and Ca-TiS 2 monolayers facilitate the acceleration of the Li 2 S decomposition reaction and Li-ion migration on their surfaces. This investigation effectively advances our understanding of the role of TiS 2 in the polysulfide conversion process and offers valuable insights into the design of cathodes in Li−S batteries.
