Improved Voltage and Cycling for Li+ Intercalation in High‐Capacity Disordered Oxyfluoride Cathodes
New high-capacity intercalation cathodes of Li2V x Cr1-x O2F with a stable disordered rock salt host framework allow a high operating voltage up to 3.5 V, good rate performance (960 Wh kg-1 at ≈1 C), and cycling stability.
متن کاملHigh Voltage Alloys for Lithium Battery Cathodes
Objective GCEP provides funding for research activities of an exploratory nature that test the feasibility and application of potential step-out ideas. These activities focus on novel approaches and innovative concepts associated with technologies that may permit reductions in greenhouse gas emissions on a global scale. While exploratory activities are limited to $100K and a one-year performanc...
متن کاملNanoscale Morphological and Chemical Changes of High Voltage Lithium–Manganese Rich NMC Composite Cathodes with Cycling
Understanding the evolution of chemical composition and morphology of battery materials during electrochemical cycling is fundamental to extending battery cycle life and ensuring safety. This is particularly true for the much debated high energy density (high voltage) lithium-manganese rich cathode material of composition Li(1 + x)M(1 - x)O2 (M = Mn, Co, Ni). In this study we combine full-field...
متن کاملSodium bicarbonate and high-intensity-cycling capacity: variability in responses.
PURPOSE To determine whether gastrointestinal (GI) distress affects the ergogenicity of sodium bicarbonate and whether the degree of alkalemia or other metabolic responses is different between individuals who improve exercise capacity and those who do not. METHODS Twenty-one men completed 2 cycling-capacity tests at 110% of maximum power output. Participants were supplemented with 0.3 g/kg bo...
متن کاملHigh-purity iron pyrite (FeS2) nanowires as high-capacity nanostructured cathodes for lithium-ion batteries.
Iron pyrite is an earth-abundant and inexpensive material that has long been interesting for electrochemical energy storage and solar energy conversion. A large-scale conversion synthesis of phase-pure pyrite nanowires has been developed for the first time. Nano-pyrite cathodes exhibited high Li-storage capacity and excellent capacity retention in Li/pyrite batteries using a liquid electrolyte,...
