TL;DR: In this article, the electrochemical reaction of lithium with crystallized -Fe2O3 (hematite) has been studied by means of in situ X-ray diffraction, and it is shown that a careful control of the texture/particle size of electrochemically active oxide particles is likely an important variable that has been largely disregarded for such properties.

TL;DR: In this paper, a topotactic two-phase electrochemical mechanism between LiMnPO 4 and the fully delithiated phase MnPO 4 (a = 5.909(5) A, b = 9.64(1) A), and c = 4.768(6) A).

TL;DR: In this paper, chemical reactions taking place at elevated temperatures in a polymer-bonded lithiated carbon anode were studied by differential scanning calorimetry, and the influences of parameters such as degree of intercalation, number of cycles, specific surface area, and chemical nature of the binder were elucidated.

TL;DR: In this article, the first stage of the electrochemical reduction of crystallized spinel in lithium cells was investigated by means of in situ X-ray diffraction, and it was shown that the formation of the intermediate phase was highly dependent on the discharge rate, the texture of the active material (i.e., crystallite size, specific surface area), and the cycling temperature.

TL;DR: In this article, a survey of the chemical stability of high surface area LiMn{sub 2}O{sub 4} in various Li-based electrolytes was performed as a function of temperature.
