Journal ArticleDOI
High-rate electrochemical energy storage through Li+ intercalation pseudocapacitance
Veronica Augustyn,Jeremy Come,Jeremy Come,Michael A. Lowe,J. W. Kim,Pierre-Louis Taberna,Pierre-Louis Taberna,Sarah H. Tolbert,Héctor D. Abruña,Patrice Simon,Patrice Simon,Bruce Dunn +11 more
TL;DR: This work quantifies the kinetics of charge storage in T-Nb2O5: currents that vary inversely with time, charge-storage capacity that is mostly independent of rate, and redox peaks that exhibit small voltage offsets even at high rates.
Journal ArticleDOI
The Effect of Crystallinity on the Rapid Pseudocapacitive Response of Nb2O5
TL;DR: In this article, the electrochemical properties of Nb2O5 were investigated and it was shown that the orthorhombic and pseudohexagonal phases of the material undergo fast faradaic reactions that lead to high specific capacitance in short charging times.
Journal ArticleDOI
Electrochemical Kinetics of Nanostructured Nb2O5 Electrodes
Jeremy Come,Veronica Augustyn,J. W. Kim,Patrick Rozier,Pierre-Louis Taberna,Pavel Gogotsi,Jeffrey W. Long,Bruce Dunn,Patrice Simon +8 more
TL;DR: In this paper, Li+ intercalation within specific planes in the orthorhombic structure is characterized as being an intrinsic property of Nb2O5 that facilitates the design of electrodes for capacitive storage devices.
Journal ArticleDOI
Fabrication of membranes for the liquid separation: Part 2: Microfiltration membranes prepared from immiscible blends containing polysulfone and poly(1-vinylpyrrolidone-co-acrylonitrile) copolymers
E.J. Moon,J. W. Kim,C. K. Kim +2 more
TL;DR: In this paper, microfiltration membranes are prepared from immiscible blends of polysulfone (PSf) and poly(1-vinylpyrrolidone-co-acrylonitrile) copolymers via traditional phase inversion process.
Journal ArticleDOI
Metal-Matrix Nanocomposites with Tailored Coefficients of Thermal Expansion for Improved Thermomechanical Reliability
TL;DR: In this article, the authors describe the development of metal-matrix nanocomposites with tailorable negative thermal expansion (CTEs) for use as electrodes or as interfacial bonding layers for creating segmented TE elements.
