Journal ArticleDOI
Phospho‐olivines as Positive‐Electrode Materials for Rechargeable Lithium Batteries
TL;DR: In this article, the authors showed that a reversible loss in capacity with increasing current density appears to be associated with a diffusion-limited transfer of lithium across the two-phase interface.
Journal ArticleDOI
Effect of Structure on the Fe3 + / Fe2 + Redox Couple in Iron Phosphates
A. K. Padhi,K. S. Nanjundaswamy,Christian Masquelier,Shigeto Okada,Shigeto Okada,John B. Goodenough +5 more
TL;DR: In this article, the role of structure on the position of the octahedral redox couple in compounds having the same polyanions, four iron phosphates:, and were investigated.
PatentDOI
Cathode materials for secondary (rechargeable) lithium batteries
Michel B. Armand,John B. Goodenough,A. K. Padhi,Kirakadu S. Nanjundaswamy,Christian Masquelier +4 more
TL;DR: In this article, the authors proposed transition-metal compounds having the ordered-olivine, a modified olivine, or the rhombohedral NASICON structure and the polyanion (PO 4 ) 3− as at least one constituent for use as electrode material for alkali-ion rechargeable batteries.
Journal ArticleDOI
Mapping of Transition Metal Redox Energies in Phosphates with NASICON Structure by Lithium Intercalation
TL;DR: In this paper, the position of transition metal redox energies with respect to the Fermi energy of lithium in phosphates with sodium super ionic conductor (NASICON) framework were determined electrochemically upon lithium intercalation.
Journal ArticleDOI
Synthesis, redox potential evaluation and electrochemical characteristics of NASICON-related-3D framework compounds
K. S. Nanjundaswamy,A. K. Padhi,John B. Goodenough,Shigeto Okada,Hideaki Ohtsuka,Hajime Arai,Jun-Ichi Yamaki +6 more
TL;DR: In this paper, the authors synthesized and electrochemically characterized the framework compounds M2(SO4)3 with M = (Ti Fe), (V Fe), Fe, Fe and LixM2(PO4) 3 with Lix
