A crystalline electrode made up of 75% active material (boron-incorporated diamond, BID), 10% poly vinylidene fluoride + 1-methyl-2pyrrolidinone and 15% carbon black was synthesized using the combustion technique at 1173 K for one hour to make homogeneous distribution of sub-micron sized particles. Characterization of the electrode material has been performed through X-ray diffraction, Raman Spectroscopy and Scanning electron microscopy before using it in lithium-ion batteries. The amount of Li in the boron-doped diamond strongly affects its electrochemical performance as electrode. Electrochemical measurements have illustrated much better cycling stability in the -4.0 to 4.5V range at different rates of current. The successful electrochemical activity of boron-incorporated diamond electrode along with lithium electrode insertion in Li + ion batteries has been reported and discussed here. The peak current shows an almost linear relationship with square root of the scan rate. In addition, effective electrode area was estimated to be 0.54 cm(2). Electronic properties of Li-containing electrodes were investigated using DFT approach which showed polaronic conducting behavior which seems advantageous for high power capability.
