Abstract
Description
Technical Field
[0001] This utility model relates to the field of lithium battery anode material production technology, specifically to an aluminum busbar for ultra-high current circuit connection. Background Technology
[0002] The production of lithium batteries is inseparable from artificial graphite. Graphitization is a key process in the production of artificial graphite, mainly utilizing thermal activation to transform thermodynamically unstable carbon atoms from a disordered layer structure to an ordered graphite crystal structure. Current processes all involve installing one dedicated transformer per production line. If the transformer fails, the lack of backup power will interrupt the graphitization process, resulting in the loss of the entire batch of products, and in severe cases, even scrapping the entire batch. Our optimized solution is to connect two adjacent production lines in parallel, allowing the two transformers to provide mutual backup in case of emergencies. Due to the extremely large current supplied to the graphitization furnace, the circuit breakers required for the parallel connection of the two lines are not available on the market. Therefore, we designed an ultra-high current line connecting aluminum busbar for this application. Utility Model Content
