Graphite-based anodes

WebIn this paper, micro embossing is proposed as a novel material-preserving approach for graphite-based anodes to improve their performance. A metal stamp with well-defined laser-structured micro pins was developed first. Subsequently, a lab scale process was developed to imprint a defined perforation pattern on calendered graphite anodes. WebNano-Sn/Graphite anodes for lithium-ion batteries are successfully fabricated by the method of laser sintering on the copper current collectors. Then microstructures and electrochemical properties of the electrodes are investigated in details.
