Abstract Aqueous zinc‐ion batteries (AZIBs) have aroused continuously increasing attention for grid‐scale energy storage applications. However, the progress of AZIBs is largely plagued by their sluggish reaction kinetics and poor structural reversibility, which are closely related to desolvation process hydrated Zn 2+ . Herein, a strategy local coordination engineering proposed modulate both surface bulk structure conventional α‐MnO 2 cathode overcome these issues. Theoretical simulations...

Abstract The rapid progress in mass-market applications of metal-ion batteries intensifies the development economically feasible electrode materials based on earth-abundant elements. Here, we report a record-breaking titanium-based positive material, KTiPO 4 F, exhibiting superior potential 3.6 V potassium-ion cell, which is extraordinarily high for titanium redox transitions. We hypothesize that such an unexpectedly major boost benefits from synergy cumulative inductive effect two anions...

Because of the outstanding discharge capacity provided by oxygen redox activity, Li-rich layered oxide positive electrode materials for Li-ion batteries attract tremendous attention. However, there is still no full consensus on role that ionocovalency transition metal (TM)–oxygen (O) chemical bonding plays in reversibility as well both local crystal and electronic structure transformations. Here, we managed to tune cationic/anionic contributions overall electrochemical activity using...
This work is devoted to a novel efficient strategy for single-walled carbon nanotube doping employing heat treatment with nitrogen dioxide. Unlike numerous reports of unstable NO2 at room temperature, our method combines high efficiency and stability, enabled by temperature-dependent adsorption dioxide on the surface. We reveal that stability increases temperature reaching maxima 300 °C avoiding any detrimental effect structure optical transmittance. As result, we demonstrate doped...
The novel Ti-containing anode for the K-ion battery.
Potassium-ion batteries are an emerging post-lithium technology that considered ecologically and economically benign in terms of raw materials' abundance cost. Conventional cell configurations employ flammable liquid electrolytes impose safety concerns, as well considerable degrees irreversible side reactions at the reactive electrode interfaces (especially against potassium metal), resulting a rapid capacity fade. While being inherently safer, solid polymer may present solution to losses...
