Equipment for Continuously Processing Electrochemical Device or Component for Increasing Capacity Thereof

Simple SummaryContent extracted from patent full text and abstract with AI.

The invention provides equipment for the continuous processing of battery electrodes—especially for lithium or similar metal batteries—by depositing additional metal (such as lithium) onto an electrode through a controlled electrochemical process. This method uses two reaction chambers separated by a membrane that selectively allows metal ions to pass, while gas byproducts are safely discharged, resulting in even and high-quality metal deposition on the electrodes. This process enables more uniform and higher-capacity battery components compared to conventional methods.

Patent Abstract

Present invention is related to equipment for continuously processing electrochemical device or component for increasing capacity comprising a first reaction part (11), a second reaction part (12) and a separated layer (13) configured to be placed between the first reaction part (11) and the second reaction part (12). The first reaction part (11) comprises a counter electrode (111), a first reaction solution (113) contained in a first reaction cell (112) having a gas outlet (114). The first reaction solution (113) will produce a first non-metallic ion (1131), a second metallic ion (1132) and a third gas after conducting an electrochemical reaction. The second reaction part (12) comprises a working electrode (121) and a second reaction solution (123) containing the second metallic ion (1132) permeated through the separated layer (13) from the first reaction part (11). The second metallic ion (1132) will then be deposited as metal particles onto the working electrode (121) which has been continuously fed into the second reaction part (12). 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.
