Autor: T. Taskovic, E. R. Logan, Michael K. G. Bauer, Laurent Molino, Marc M. E. Cormier, Helena Hebecker, J. R. Dahn, David S. Hall, Ines Hamam

Publikováno v: The Journal of Physical Chemistry C. 124:12269-12280

Electrolyte systems based on binary mixtures of organic carbonate ester cosolvents have limitations in ionic transport and thus limit extreme fast charge (XFC) and high-rate cycling of energy dense...

Performance and Degradation of LiFePO4/Graphite Cells: The Impact of Water Contamination and an Evaluation of Common Electrolyte Additives

Autor: Michel B. Johnson, E. R. Logan, J. R. Dahn, Helena Hebecker, A. Eldesoky, Aidan Luscombe

Publikováno v: Journal of The Electrochemical Society. 167:130543

LiFePO4 (LFP) is an appealing cathode material for Li-ion batteries. Its superior safety and lack of expensive transition metals make LFP attractive even with the commercialization of higher specific capacity materials. In this work the performance o
