Descripción general

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.

Aplicación

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.
