Hierarchically Porous Monolithic LiFePO4/Carbon Composite Electrode Materials for High Power Lithium Ion Batteries
Abstract
A novel method for the preparation of hierarchically porous LiFePO 4 electrode materials for lithium ion batteries has been investigated. A meso/macroporous carbon monolith, a conductive framework, was prepared and infiltrated with the LiFePO 4 precursors to increase the electrode/electrolyte interface and improve the rate capability of the battery. The final LiFePO 4 /carbon monoliths feature a meso/macroporous hierarchical structure. The monoliths were calcined at increasing temperatures, from 650 to 800 °C, to determine the structural and sintering effects on the electrochemical properties of the materials. The samples were characterized using SEM, TEM, nitrogen sorption, and XRD analysis prior to electrochemical testing. The results showed that the capacity of the LiFePO 4 /carbon electrodes achieved 82% of the theoretical capacity at 0.1C discharge rate.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
