Improved Performance of the Silicon Anode for Li-Ion Batteries: Understanding the Surface Modification Mechanism of Fluoroethylene Carbonate as an Effective Electrolyte Additive
Chao Xu,Fredrik Lindgren,Bertrand Philippe,Mihaela Gorgoi,Fredrik Björefors,Kristina Edström,Torbjörn Gustafsson +6 more
TL;DR: In this article, fluoroethylene carbonate (FEC) was used as an electrolyte additive, which significantly improved the cyclability of silicon-based electrodes and suppressed further salt degradation.
Journal ArticleDOI
Nanosilicon Electrodes for Lithium-Ion Batteries: Interfacial Mechanisms Studied by Hard and Soft X-ray Photoelectron Spectroscopy
Bertrand Philippe,Bertrand Philippe,Rémi Dedryvère,Joachim Allouche,Fredrik Lindgren,Mihaela Gorgoi,Håkan Rensmo,Danielle Gonbeau,Kristina Edström +8 more
TL;DR: In this paper, the authors proposed silicon as an ideal candidate for the next generation of negative electrodes for Li-ion batteries, based on its very high rechargeable capacity and its ability to resist high power dissipation.
Journal ArticleDOI
Electronic Structure of TiO2/CH3NH3PbI3 Perovskite Solar Cell Interfaces
Rebecka Lindblad,Dongqin Bi,Byung-wook Park,Johan Oscarsson,Mihaela Gorgoi,Hans Siegbahn,Michael Odelius,Erik M. J. Johansson,Håkan Rensmo +8 more
TL;DR: The electronic structure and chemical composition of efficient CH3NH3PbI3 perovskite solar cell materials deposited onto mesoporous TiO2 were studied using photoelectron spectroscopy with hard X-rays and results indicating similar electronic structures are shown.
Journal ArticleDOI
Comparing anode and cathode electrode/electrolyte interface composition and morphology using soft and hard X-ray photoelectron spectroscopy
Sara Malmgren,Katarzyna Ciosek,Maria Hahlin,Torbjörn Gustafsson,Mihaela Gorgoi,Håkan Rensmo,Kristina Edström +6 more
TL;DR: In this article, the authors performed depth profiling on graphite and delithiated lithium iron phosphate electrodes after electrochemical cycling in a balanced full cell configura... and found that the depth profiling was performed on both graphite graphite electrodes and lithium-iron phosphate electrodes.
Journal ArticleDOI
Improved performances of nanosilicon electrodes using the salt LiFSI: a photoelectron spectroscopy study.
Bertrand Philippe,Bertrand Philippe,Rémi Dedryvère,Rémi Dedryvère,Mihaela Gorgoi,Håkan Rensmo,Danielle Gonbeau,Danielle Gonbeau,Kristina Edström +8 more
TL;DR: It is shown that LiFSI allows avoiding the fluorination process of the silicon particles surface upon long-term cycling, which is observed with the common salt LiPF6 and the favorable interactions between the binder and the active material surface are preserved.
