A new high performing lithium ion cell having new carbon based anode and new dual doped layered cathode materials. The anode is a self standing carbon fibrous material and the cathode is a dual doped Lithium cobalt oxide of general formula LiMNCoO(0.01&#x2266;x, y&#x2266;0.2) wherein M is a divalent alkaline earth metal cation and N is a divalent transition metal cation. Lithium ion cells of 2016 coin cells were assembled using the above materials deliver specific capacity of 60-85 mAhgat 1 C rate and exhibit excellent cycling stability of 90-95% even after 200 cycles when cycled between 2.9-4.1V.

Cathode material and lithium ion battery therefrom

An organic light emitting functional device with organic electron injection layer to improve the injection of electrons from the cathode in an organic light emitting diode. In particular, the device relates to the use of electron transport layer 4,7-di phenyl-1,10 phenanthroline (herein after called as BPhen) and another organic semiconductor Tetracyano quino dimethane (herein after called as TCNQ) and optimizing the thickness and doping percentage of the composition in an organic light emitting device. The main use of the composed injection layer is to balance the injection of holes from the anode side and the injection of electrons from cathode side and thus increase the efficiency of Organic light emitting diodes.

Process for growing an electron injection layer to improve the efficiency of organic light emitting diodes

The present invention provides a conducting copolymer ferromagnetic composite. Particularly, the present invention relates to a conducting copolymer of aniline and ethylene-dioxy thiophene containing ferrite particles. The present invention also provides insitu polymerization of aniline and ethylene-dioxy thiophene in the presence of ferrite particles and suitable surfactant medium. This conducting copolymer ferromagnetic composite can be used for the dissipation of electrostatic charge, for the shielding of electromagnetic interference and as absorbing of electromagnetic waves in the microwave region.
