Study of styrene butadiene rubber and sodium methyl cellulose as binder for negative electrodes in lithium-ion batteries
TL;DR: In this article, graphite and nano-silicon-based negative electrodes in lithium-ion batteries with low binder content were evaluated, and the effectiveness of styrene butadiene rubber (SBR) and various types of cellulose containing electrodes were compared to standard electrodes containing PVdF as binder.
Journal ArticleDOI
High Rate Capability of Graphite Negative Electrodes for Lithium-Ion Batteries
TL;DR: In this paper, the performance of the carbon negative electrode, which is composed of TIMREX SFG synthetic graphite material of varying particle size distribution, was investigated and a transport limitation model was proposed to explain the restrictions of the high current performance of graphite electrodes.
Journal ArticleDOI

Deyu Wang,Hilmi Buqa,Michael Crouzet,Gianluca Deghenghi,Thierry Drezen,Ivan Exnar,Nam Hee Kwon,James H. Miners,Laetitia Poletto,Michael Grätzel +9 more
TL;DR: In this paper, a novel polyol synthesis was adopted to synthesize nano-structured LiMnPO4 and the obtained material presented a good rate behavior and a very long cyclic life both at room temperature (RT) and at elevated temperature (50 degrees C) this material demonstrated improved reversible capacity of 159 mAh g(-1) at C/10 and 138 at 1C.
Journal ArticleDOI
XPS studies of graphite electrode materials for lithium ion batteries
Robert I. R. Blyth,Hilmi Buqa,Falko P. Netzer,M.G. Ramsey,Jürgen Besenhard,Peter Golob,Martin Winter +6 more
TL;DR: In this article, the authors compared graphite powders and carbon fibres as model materials for X-ray photoemission spectroscopy (XPS) studies of the effects of surface pre-treatment.
Journal ArticleDOI
A new type of nano-sized silicon/carbon composite electrode for reversible lithium insertion
TL;DR: A new type of nano-sized silicon/carbon composite shows superior electrochemical cycling properties as negative electrode material for possible use in lithium-ion batteries with respect to high reversible and low irreversible capacity, and low fading.
