Disordered Rocksalts as High‐Energy and Earth‐Abundant Li‐Ion Cathodes

Advanced Materials, EarlyView.
Disordered rocksalts with lithium excess (DRX) offer a new direction in Li‐ion cathode design beyond conventional Ni‐ and Co‐based materials. This review highlights the design principles, synthesis strategies, and performance optimization of DRX oxides and oxyfluorides for energy‐dense, sustainable batteries using Earth‐abundant transition metals and ...

Transformation of a Silicate Material for Carbon Negative Magnesia‐Based Cement via Electrochemistry

Advanced Science, EarlyView.
The transformation of a magnesium trisilicate material via water electrolysis into precursor phases necessary for magnesium‐based M‐S‐H cement is explored. The dissolution of the material mediated electrochemically is monitored, and the analysis of the resulting phases indicate their suitability as effective precursors for M‐S‐H cement.

Exploiting CO2‐Derived Carbon in Lithium‐Ion Batteries

Advanced Energy and Sustainability Research, EarlyView.
In this work, a carbon nanomaterial (CNM) extracted from CO2 reduction treatment is used as the conductive additive in lithium‐ion battery graphite anodes and LiFePO4 cathodes. The electrodes are produced by casting, using both sodium alginate as a green, water‐soluble, alternative binder.

Grave to Cradle: A Direct Recycling Approach for Over‐Discharged LiFePO4 Electric Vehicle Cells

Advanced Energy and Sustainability Research, EarlyView.
The change in the LiFePO4 (LFP) material from grave to cradle. The material is delaminated with water, before undergoing ball milling and a relithiation‐carbothermal treatment. The final step shows the fully healed LFP remanufactured as a new cathode. The purple represents LiFePO4, the light purple FePO4, black, and dark grey—the graphite and carbons ...

Olivine or Impact Melt: Nature of the "Orange" Material on Vesta from Dawn

, 2013
NASA's Dawn mission observed a great variety of colored terrains on asteroid (4) Vesta during its survey with the Framing Camera (FC). Here we present a detailed study of the orange material on Vesta, which was first observed in color ratio images ...

Expanding the application of the Eu-oxybarometer to the lherzolitic shergottites and nakhlites: Implications for the oxidation state heterogeneity of the Martian interior [PDF]

, 2009
Experimentally rehomogenized melt inclusions from the nakhlite Miller Range 03346 (MIL 03346) and the lherzolitic shergottite Allan Hills 77005 (ALH 77005) have been analyzed for their rare earth element (REE) concentrations in order to characterize the ...
