General Description
Hard carbon electrode sheet is an electrode film of activated carbon cast on copper. Hard carbon is a low-density material with extremely high microporosity. Standard electrode sheets are 5 inches x 10 inches (127 mm x 254 mm) and cast single-sided on 10 µm thick copper foil current collectors. The composition of the electrode film is 90% graphite, 5% poly(vinylidene fluoride) [PVDF] and 5% Super P. PVDF acts as binder due to its thermal and electrochemical stability and strong adhesive properties.

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 hard carbon electrode sheet is a ready-to-use anode for alkali metal ion batteries such as sodium ion batteries (SIBs), lithium ion batteries (LIBs), and potassium ion batteries. Hard carbon is the anode of choice for sodium-ion batteries, where the use of graphite as an anode in SIBs is inhibited by the inability of sodium ions to form a binary graphite intercalation compound. Hard carbon offers a low insertion/deinsertion potential (~0.1 V Na/Na+) ideal for achieving high voltages. With an experimental capacity of 240 mAh/g and areal capacity of 2.32 mAh/cm2, our electrodes demonstrate outstanding electrochemical performance.
