Sustainability Analysis and Energy Footprint-Based Design in the Product Lifecycle
In this paper, we study the concept of energy efficiency and specific energy consumption (SEC) of manufacturing processes.
Transition Metal Oxides as Cathodes for Li-ion battery: Structure, stability and substitution effects
First–principles DFT simulations are computationally demanding but are reasonably accurate in predicting properties of battery cathode materials. Properties relevant to selection of cathode
material include electrochemical potential, structural stability, energy/power density and cycle life etc. Computational screening of materials speeds up the process of material discovery by
saving on costs of experiments and time. In addition, it helps in developing correlation between properties and structural and chemical aspects. Here we analyze some of these aspects for the
Machine Level Energy Efficiency Analysis in Discrete Manufacturing for a Sustainable Energy Infrastructure
Sustainable economic development necessitates a careful design of the energy infrastructure.
Tuning electrochemical potential of LiCoO2 with cation substitution: first principles predictions and electronic origin
We simulate substitution of various elements (X = Be, Mg, Al, Ga, Si and Ti) for Co using first-principles density functional theory and predict changes in its electrochemical potential. While the electrochemical potential of LiCoO2 is enhanced with substitution of Be, Mg, Al and Ga for Co, an opposite effect is predicted of Si and Ti substitution.
