Publication number: 20140205902Abstract: Aspects of the invention are directed to a method for forming a hybrid structure. Initially, a wire is received and an encapsulating film is deposited on the wire. Subsequently, the wire is selectively removed to leave a hollow tube formed of the encapsulating film. A plurality of active particles are then placed into the hollow tube by immersing the hollow tube in a suspension comprising the plurality of active particles and a liquid. Lastly, the hollow tube and the plurality of active particles therein are removed from the suspension and allowed to dry so as to form a cluster of active particles at least partially encapsulated by the encapsulating film.Type: ApplicationFiled: January 22, 2013Publication date: July 24, 2014Applicant: BLUESTONE GLOBAL TECH LIMITEDInventors: Xin Zhao, Xuesong Li, Yu-Ming Lin

Publication number: 20140113074Abstract: Improved methods for synthesizing large area thin films are disclosed, which result in films of enhanced width. The methods comprise providing a separator material which is rolled or wound up, along with the metallic foil substrate on which the thin film is to be deposited, to form a coiled composite which is then subjected to conventional chemical vapor deposition. Optionally, a winding tool may be used to aid in the rolling process. The methods enable a many-fold increase in the effective width of the substrate to be achieved.Type: ApplicationFiled: October 19, 2012Publication date: April 24, 2014Applicant: BLUESTONE GLOBAL TECH LTD.Inventors: Xuesong LI, Jia-Hung WU

Publication number: 20140030636Abstract: In general, in one aspect, a graphene film is used as a protective layer for current collectors in electrochemical energy conversion and storage devices. The graphene film inhibits passivation or corrosion of the underlying metals of the current collectors without adding additional weight or volume to the devices. The graphene film is highly conductive so the coated current collectors maintain conductivity as high as that of underlying metals. The protective nature of the graphene film enables less corrosion resistant, less costly and/or lighter weight metals to be utilized as current collectors. The graphene film may be formed directly on Cu or Ni current collectors using chemical vapor deposition (CVD) or may be transferred to other types of current collectors after formation. The graphene film coated current collectors may be utilized in batteries, super capacitors, dye-sensitized solar cells, and fuel and electrolytic cells.Type: ApplicationFiled: July 26, 2012Publication date: January 30, 2014Applicant: Bluestone Global TechInventors: Xin Zhao, Yu-Ming Lin
