Na-ion batteries (NIBs) are an important technological alternative to Li-ion (LIBs) for developing energy storage systems that cost-effective and less constrained by geographical supply chains, with similar densities. Analogous LIBs, cathodes play a critical role in determining the density of NIBs, layered transition metal oxide compounds widely used as NIB cathodes. However, instability-driven...

Aqueous zinc-ion batteries (AZIBs) and, in particular, Zn//MnO2 rechargeable have attracted great attention due to the abundant natural resources of zinc and manganese, low cost, environmental friendliness, high operating voltage. Among various ways improve electrochemical performance MnO2-based cathodes, development MnO2 cathodes doped with metal ions or composites conducting polymers has show...

Co-Free Layered Cathodes In article number 2204241, Hailong Wang, Xiangming He, and co-workers report a cation vacancy assisted Al substitution strategy to enhance the reversibility of Co-free layered cathodes. A small amount vacancies greatly enhances Li+ diffusivity effectively mitigates lattice strain cathode, which gives rise large reversible capacity enhanced coulombic efficiency during el...

A novel bioelectrochemical reactor assembled with cooperative cathodes of chemical cathode and bio-cathode (BER CC ) excess sludge as the anodic substrate obtained continuous effective Cr(VI) reduction. Cooperative in BER stimulated growth electrochemically active microorganisms such Geobacter sp. Shewanella biofilm produced 8.21 ± 0.64 mg C/(L·h) more electrons than dual cathodes, which enhanc...

Investigation of some reaction products possibly produced by electrolyzing with Au and Pd electrodes in Na2SO4, K2CO3, and KOH light water solutions was made. The electrolysis was performed for 7 days with a constant current of 1 A. After the electrolysis the elements accumulated in the electrode were analyzed by means of AES. In every case a notable amount of Fe atoms were detected together wi...

Component potential modelling based on solid-oxide electrochemistry is used to study a single-particle configuration where a hemispherical LSM particle sits on a YSZ electrolyte half-space. The primary comparison is between two pathways: one where oxide ions travel on the particle surface; the other where these ions travel through the bulk particle interior. The systems that model each of the p...

In the manufacturing process of lithium-ion batteries, current organic solvent-based processes will inevitably be replaced with eco-friendly water-based processes. For this purpose, organic-soluble binder should a water-soluble or water-dispersed binder. study, new polyacrylate latex dispersed in water was successfully applied as battery cathodes for first time. One biggest advantages is that i...

My first three experiments conducted at NHE using the Fleischmann-Pons (F-P) Dewar type cells investigated the Pd-Ce-B, Pd-B, and Pd-Ce alloy cathodes. Significant excess power was produced from the cells using the Pd-B and Pd-Ce alloy cathodes. The Pd-Ce-B alloy, in contrast, showed no measureable excess power effects. Previous experiments at China Lake using similar Pd-B alloy cathodes prepar...

The status of the polarized electron source development program at SLAC will be reviewed. Emission currents of 60 A, corresponding to a space charge limited current density of 180 A/cm2. have been obtained from GaAs photocathodes. Electron beam polarization 20% greater than that obtainable from GaAs cathodes has been observed from multilayer &As-GaAlAs structures. Work in progress to produce hi...
