Battery and ultracapacitor electrodes are traditionally made with at least one polymeric binder material that mechanically holds the various, powder like, raw materials together. In addition to increasing the electrode resistance, the binder is assumed to be at least partially responsible for the performance degradation over time for rechargeable Lithium batteries.

We present here for the
