摘要： An electrode has a diamond layer (500,520) with an inner-side oriented toward one or both of the first surface and the second surface of the substrate and an active layer having a composition that includes an element capable of lithium-atom insertion positioned on the outer-side of the layer(s) of diamond. The diamond layer includes polycrystalline diamond and a p-dopant element and has a doping level equal to or greater than 10 20 atoms/cm 3 The doped diamond layer, preferably doped with boron, is essentially impermeable to lithium, which prevents lithium migration from the active layer during cycling of the electrode when utilized as one or more of an anode and cathode in a Li-ion battery. The boron-doped diamond electrode exhibited a stable capacity of about 250 μΑhcm -2 and a coulombic efficiency of about 90 to 95% over 30 cycles. The electrode can be manufactured by CVD and electrochemical deposition techniques.
