Electrochemical lithium reactivity with nanotextured anatase-type TiO2

Journal of Materials Chemistry (2005)

Guillaume Sudant Emmanuel Baudrin Dominique Larcher Jean‐Marie Tarascon

Anatase TiO2 particles were synthesized by a two-step method consisting of the preparation of a solid precursor through hydrolysis of titanium alkoxide followed by heat treatment at different temperatures under ambient air. This simple method led to a highly porous material with a 200 nm homogenous particle size, while the BET specific surface area and crystallite sizes evolved between 49 m2 g−1 to 223 m2 g−1 and from 17.0 nm to 6.3 nm, respectively. Their electrochemical performances clearly revealed the beneficial influence of the divided texture of anatase-type TiO2 on the reactivity with lithium, namely in terms of reversibility. Furthermore, we showed that the TiO2 texture strongly affects the extent of the solid solution domain. Finally, through a simple chemical titration it was possible to clearly quantify the capacitive/faradaic contributions of the electrochemical reaction.

Electrochemical Reactivity of KSi and NaSi Zintl Phases with Lithium

ECS Electrochemistry Letters (2015)

Vincent Seznéc Premkumar Senguttuvan Dominique Larcher Jean‐Marie Tarascon

The electrochemical reactions of NaSi and KSi Zintl phases with lithium (0–2.5 V) proceed very differently. Na/K is partially removed on first oxidation with a complete amorphization for NaSi or growth of a new crystallized KxSi phase for KSi. Upon discharge, metallic K is partially extruded and a Li-K-Si (Li15Si4–type) phase is formed. For NaSi, metallic Na is also chased on discharge but crystallization of Li-Na-Si (Li15Si4–type) phase is delayed at the second discharge. The amorphization of Li15KxSi4 proceeds through a ∼0.40 Volts charge plateau but crystallized Li15NaxSi4 does not show this feature and electrochemically behaves similarly to amorphous LixSi.

Effect of Particle Size on Lithium Intercalation into α-Fe[sub 2]O[sub 3]

Journal of The Electrochemical Society (2002)

Dominique Larcher Christian Masquelier D. Bonnin Y. Chabre V. Masson

The electrochemical reaction of lithium with crystallized (hematite) has been studied by means of in situ X-ray diffraction. When reacting large particles we observed the well-known transformation of the close-packed anionic array from hexagonal (hc) to cubic (ccp) stacking. At the early stage of the reduction, a very small amount of lithium can be inserted before this structural transformation occurs. Nanosize made of fine monolithic particles (200 Å) behaves very different, since up to one Li per formula unit can be inserted in the corundum structure without phase transformation. To our knowledge, this is the first time this phase is maintained for such large values. This cationic insertion was found to come with a small cell volume expansion evaluated to 1%. Unsuccessful attempts to increase the values on large particles by decreasing the applied discharge current density suggest that the particle size is the only parameter involved. The better structural reversibility of this monophasic process compared to the biphasic one was confirmed by electrochemical cycling tests conducted with hematite samples of various particle sizes. Therefore, by using nanosize particles, we can drastically increase the critical Li concentration required to observe the transition. This work demonstrates 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. © 2002 The Electrochemical Society.

Towards a Fundamental Understanding of the Improved Electrochemical Performance of Silicon–Carbon Composites

Advanced Functional Materials (2007)

Juliette A. Saint Mathieu Morcrette Dominique Larcher Lydia Laffont S. D. Beattie

Abstract Silicon–carbon composites consisting of Si particles embedded in a dense and non‐porous carbon matrix are prepared by the pyrolysis of intimate mixtures of poly(vinyl chloride) (PVC) and Si powder at 900 °C under a flow of N 2 . In contrast to bare micrometer‐sized (1–10 μm) and nanometer‐sized (10–100 nm) Si powders, which show poor cycling behavior with almost no capacity remaining after 15 cycles, the texture of the composite is seen to greatly enhance the reversibility of the alloying reaction of Si with Li. For instance, a capacity of ca. 1000 mA h g –1 is achieved for 20 cycles (0–2.0 V vs. Li + /Li) for a silicon–carbon composite containing nanometer‐sized Si particles. We also demonstrate that a mild manual grinding treatment degrades the cycling performance of the composites to levels as low as the parent Si, even though free Si is not released. The electrochemical measurements in conjunction with Raman spectroscopy data indicate that a huge stress is exerted on the Si domains by the in situ formed carbon. This carbon‐induced stress is found to disappear during the milling of the composites, indicating that the carbon‐induced pressure, along with the accompanying improvement in electrical connectivity, are the key parameters for the improved cycling behavior of Si versus Li.
