. Picture 2: Selection of Hard Connection Copper Bars Copper soft connection bars. The copper soft connection bars are constructed by stacking multiple layers of copper foil, each ranging from 0.05 to 0.3 mm in thickness. These layers are bonded through high -currentheating and pressure welding via polymer diffusion welding. The bar undergoes various processes such as grinding, punching, cutting, polishing, bending, and surface treatment, resulting in a highly flexible product. This flexibility allows the copper soft connection bar to be shaped in various bending, twisting, and folding forms to fit the required space within the battery pack of new energy vehicles. The battery pack of a new energy vehicle is composed of multiple battery modules, which require connecting copper bars for inter -moduleconnections. This product is extensively used in the connections between cells and modules within the battery pack of new energy vehicles. It enhances conductivity, compensates for installation errors in the electrical structure of the battery pack, and serves as a shock absorption mechanism. 90 Picture 3: Selection of Soft Connection Copper Bars For the six months ended December31, 2024 and the fiscal years ended June30, 2024 and 2023, our revenues generated from the sales of our “Xinxu” branded T2 red copper bar products, including our hard connection copper bars and soft connection copper bars, were approximately $7.05million, $4.17million and $10.16million, respectively, accounting for approximately 10.60%, 3.94% and 5.95%, respectively, of our total revenues. T2 Tin-plated Copper Bars Copper bars usually have high current power concentrated in the bar for electricity distribution. Due to the large amount of electricity running through these bars, they become very hot. At high temperatures, bare copper bar begins to oxidize and oxidized copper usually has poor electrical conductivity. As a result, copper bars are usually plated with tin flashing, which are more resistant to oxidation than bare copper and are capable of reaching higher temperatures without degrading and losing their conductivity. One of the advantages of tin flashing is that it is more cost effective than silver flashing and more corrosion resistant in certain industrial environments that contain Hydrogen Sulfide. As a result, tin -platedcopper bars protect against atmospheric corrosion, and hence provide longer life under corrosive atmosphere. We do not process tin flashing and all tin flashing is processed by third party processors who receive T2 copper bars from us, tin -flashthe copper bars, and
