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.
