Correction for 'An acid-free rechargeable battery based on PbSO4 and spinel LiMn2O4' by Yu Liu et al., Chem. Commun., 2014, 50, 13714-13717.

The Li 1s XPS (X-ray Photoelectron Spectroscopy) spectra of LiMn2O4, which is one of the major positive-electrode materials in lithium-ion rechargeable batteries, and MnO2 as a reference material, were measured by a laboratory-type XPS spectrometer. The Li 1s peak was not observed in the spectra excited by the Mg Kalpha line (1253.6 eV), because the Li 1s peak overlapped the background of the M...

The present study used the Pechini process with a continuous furnace to synthesize LiMn2O4 powders. After heat treatment, the particle size and lattice constant of the LiMn2O4 powder increased. For heat treatment cathode powders (LMO800), due to both the average valence of Mn cations approaching the theoretical value and the higher crystalinity, the discharge capacities are raised significantly...

Control over porosity and exposed highly reactive facets is challenging in the area of materials science. Materials with high porosity and reactivity of exposed facets are favorable candidates in catalysis and energy storage. Here we demonstrate a facile template-free route to synthesize nanoporous LiMn2O4 nanosheets composed of single-crystalline LiMn2O4 nanorods with exposed {111} facets via ...

LiMn2O4 and LiMn1.5M0.5O4 (M: Ni, Cu, Co) doped particles have been synthetized by sol-gel. Particles between 50 200 nm were obtained with the cubic spinel structure of LiMn2O4. Ni doping shows a more efficient substitution in octahedral 16d site, replacing Mn3+ ion, improving important drawback poor cycling behavior The average pore size decrease addition elements from 2.9 to 2.6 nm. Thermal a...

Rechargeable batteries made from low-cost and abundant materials operating in safe aqueous electrolytes are attractive for large-scale energy storage. Sodium-ion battery is considered as a potential alternative of current lithium-ion battery. As sodium-intercalation compounds suitable for aqueous batteries are limited, we adopt a novel concept of Li(+)/Na(+) mixed-ion electrolytes to create two...
