An Investigation of the Fe-Mn-Si System for Li-Ion Battery Negative Electrodes
(The Electrochemical Society, 2019-01-03)
Fe-Mn-Si alloys prepared by ball milling were investigated as negative electrodes for Li-ion batteries. X-ray diffraction and room temperature 57Fe Mössbauer measurements were used to characterize alloy structure, which ...
Spherically Smooth Cathode Particles by Mechanofusion Processing
(The Electrochemical Society, 2019-08-27)
Surface modification has been shown to be useful for improving the cycling performance of cathode materials. Typically hetero-compositional coatings are applied on cathode particle surfaces using methods, such as aqueous ...
Quantitative Determination of Carbon Dioxide Content in Organic Electrolytes by Infrared Spectroscopy
(The Electrochemical Society, 2019-07-09)
CO2 has been shown to be an effective additive to improve the cycling characteristics of silicon negative electrodes for Li-ion batteries. However, a quantitative technique for measuring the CO2 content in electrolyte is ...
Stabilizing NaCrO2 by Sodium Site Doping with Calcium
(The Electrochemical Society, 2019-06-14)
Layered cathode materials based on abundant, low cost raw materials have garnered interest in recent years. O3-type NaCrO2 is a promising cathode material as it offers decent energy density and is easy to synthesize. In ...
