A method of electroplating (or electrodeposition) carbon to coat anode and cathode active materials used in Li-ion batteries (LIBs) for improving their cycle life. The electroplating of the carbon coating from the carbon source is ultrafast, preferably taking less than 10 seconds. The carbon source can be comprised of an acetonitrile, methanol, ethanol, acetonitrile, nitromethane, nitroethane or N,N-dimethylformamide (DMF) solution. The protective carbon coating may be used also in gas sensors, biological cell sensors, supercapacitors, catalysts for fuel cells and metal air batteries, nano and optoelectronic devices, filtration devices, structural components, and energy storage devices.

Lithiated transition metal oxides

A method of electrodepositing a transition metal oxide on to the surface of cathode or anode active materials used in Li-ion batteries, using an aqueous media. The transition metal oxide coating protects the cathode or anode active materials once they are fully delithiated or fully lithiated, respectively. The protective coating may be used also in gas sensors, biological cell sensors, supercapacitors, catalysts for fuel cells and metal air batteries, nano and optoelectronic devices, filtration devices, structural components, and energy storage devices.

A Raman-based spatial analysis method of detecting surface flaws. Special filters and optics are used to acquire filtered Raman response data from a portion of the surface. The filtered Raman response data represents the Raman response of the surface at a selected frequency. A camera records the response, thereby providing a two dimensional image of the portion of the surface. The image may be analyzed to determine whether that portion has desired thickness and chemical characteristics.

Surface flaw detection using spatial raman-based imaging

A method of controlling a pulsed laser deposition process. A spectroscope is used to acquire Raman response data from a substrate as it is being coated with a film. A processor compares the response data to reference data, which may represent an uncoated substrate or an ideal film. In the former case, the attenuation of the response signal is used to indicate film thickness. In the former case, the peak characteristics of the film can be used to indicate its chemical properties. The processor may be further programmed to compare deposition rates, reaction rates, and transport rates to model data. The processor makes decisions regarding equipment control based on these comparisons. It may access heuristic rules to aid in decision making where several factors are involved.
