    Abstract: Present invention is related to equipment for continuously processing electrochemical device or component for increasing capacity comprising a first reaction part, a second reaction part and a separated layer configured to be placed between the first reaction part and the second reaction part. The first reaction part comprises a counter electrode, a first reaction solution contained in a first reaction cell having a gas outlet. The first reaction solution will produce a first non-metallic ion, a second metallic ion and a third gas after conducting an electrochemical reaction. The second reaction part comprises a working electrode and a second reaction solution containing the second metallic ion permeated through the separated layer from the first reaction part. The second metallic ion will then be deposited as metal particles onto the working electrode which has been continuously fed into the second reaction part. The present invention provides equipment which can continuously produce electrode with extra or additional lithium source without the effect of the gas byproduct with more evenly distribution and high quality.

    Abstract: Present invention is related to a metallic particle-deposition substrate having a metal substrate and multiple metallic particles attached thereon. The metallic particles are nano-particles with at least 90% of these nano-particles as single layer being evenly dispersed on the metal substrate. Each of the metallic particle is isolated without toughing or overlapping. The metal substrate has different material than the metallic particles in each preferred embodiment in the present invention. More preferably, at least 80% of the metallic particles have the distance between each metallic particle is at a range of 2-6 nm for better generation of hotspot effects. The present invention provides a fast production method for producing the substrate with heterogeneous interface. The metallic particles are evenly attached to the surface of the metal substrate to obtain better surface enhanced Raman effect as to apply for sensors in all kinds of field.
