Summary: This study investigates the effect of oxide modification on the fast lithium intercalation on cathode surfaces using in situ neutron reflectometry. The results show that the modified cathode exhibits superior rate capability due to the formation of a dense cathode-electrolyte interphase (CEI). The fast desolvation of lithium on the CEI contributes to the high rate capability of surface-modified cathodes.

Summary: This study presents a stable and dendrite-free potassium metal battery (PMB) with a cathode composed of Na+ and K+ co-intercalated vanadate (NKVO) and a liquid NaK alloy anode. The MXene-derived Na+-pillared NKVO exhibits improved specific capacities, rate performance, and cycle stability compared to the Na+-free counterpart. The study also demonstrates that thermally-treated carbon paper allows high surface tension liquid NaK alloy to adhere readily, enabling dendrite-free metal anodes. By clarifying the role of foreign intercalating cations, this study may lead to a more rational design of stable and high-performance electrode materials.

Summary: Current bottlenecks in cobalt supply have led to the development of cobalt-free cathodes with high energy density for commercial battery application. In this study, different cobalt-containing and cobalt-free cathode materials were synthesized and their electrochemical performance in Li-rich layered oxides (LLOs) investigated. The presence of cobalt was found to promote oxidation reactions and contribute to higher capacity at voltages above 4.5 V, leading to oxygen release and irreversible structural transformations. The cobalt-free cathode exhibited better cycling stability and lower initial discharge capacity compared to the cobalt-containing cathodes.

Summary: Through electrochemical methods and characterization techniques, we studied the reaction mechanism of capacity reactivation in Ag0.33V2O5 cathodes. It was found that the formation of a new phase Zn-3(OH)(2)V2O7 ·2H2O on the initial cathodes prevented the dissolution of vanadate and resulted in capacity increase. Moreover, the reconstructed Zn-3(OH)(2)V2O7 ·2H2O exhibited unique intercalation pseudocapacitive behavior, facilitating faster ionic diffusion and improving electrochemical performance.
