Description générale

Graphite electrode sheet is a ready-to-use graphite anode film, cast single-sided on 10 µm thick copper foil current collectors. The sheets are 5 inches x 10 inches (127 mm x 254 mm). The composition is 90% graphite, 5% Poly(vinylidene fluoride) [PVDF] and 5% Carbon Black. PVDF acts as binder due to its thermal and electrochemical stability.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Click here for more information.

Application

Our graphite electrode sheet is ready-to-use as an anode in rechargeable batteries, especially lithium-ion batteries and potassium-ion batteries. The primary advantages of graphite electrodes are a low insertion/deinsertion potential (0.1V vs. Li/Li+) and a high capacity, exceeding 340 mAh/g, coupled with stable cycling performance from the lack of dendrite formation. Our graphite electrodes have a high active material loading (90%) and achieve high areal capacity (2.4 mAh/cm2), allowing them to operate even at high charge currents like 5C. These electrodes offer excellent, consistent performance making them useful for research as a benchmark and counter electrode for experimental studies of cathode and electrolyte optimization as well as mechanistic in operando studies.
