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.

Optimized LiFePO4 for Lithium Battery Cathodes
TL;DR: LiFePO 4 powders were synthesized under various conditions and the performance of the cathodes was evaluated using coin cells, the samples were characterized by X-ray diffraction, scanning electron microscope observations, Brunauer, Emmett, and Teller surface area measurements, particle-size distribution measurements, and Mossbauer spectroscopy.

Electroactivity of natural and synthetic triphylite
TL;DR: In this paper, the electrochemical behavior of three triphylite (LiFePO4) ores from different mining localities has been investigated, and the best results were obtained with carbon coatings coming from the decomposition of a modified polycyclic aromatic.

Thermal stability of LixCoO2, LixNiO2 and λ-MnO2 and consequences for the safety of Li-ion cells
TL;DR: In this paper, the authors studied the thermal decomposition of Li-ion cells in inert gas and found that the nickel materials are least stable, the manganese compounds are most stable, and that the cobalt compounds show intermediate behaviour.
