The Effect of Electrode Binders to Electrochemical Properties of Negative Electrode Materials

This paper deals with various types of electrode binders used in lithium-ion batteries. The electrode binders play important role in battery, the binders directly affect almost all aspect of electrode characteristics. As the one of the most import parameter is the electrode charge-discharge long term stability. The three binders have been tested in context of negative electrode in lithium-ion battery. The natural graphite has been chosen as an active electrode material. The natural graphite takes majority as negative electrode material on commercial market with lithium-ion batteries. The three kind of binders was established for testing: polyvinylidene fluoride (PVDF), styrene-butadiene rubber (SBR) and polyimide P84. The influence of these binders on charge-discharge stability are evaluated and described in this paper.
