Abstract: A spirally-wound battery structure and a method for producing the same is provided. In the method, a power-supplying electrode plate spirally winds a hollow cylinder and has first conductive tabs and second conductive tabs. A first conductive terminal plate and a second conductive terminal plate are inserted into the hollow cylinder. Conductive welding sheets sleeve the conductive terminal plates to clamp the conductive tabs between the conductive welding sheet and the conductive terminal plate. The conductive welding sheet, the conductive tabs, and the conductive terminal plate are welded with laser. A casing encapsulates the hollow cylinder, the power-supplying electrode plate, the first conductive tabs, the second conductive tabs, the first conductive welding sheet, and the second conductive welding sheet. The first conductive terminal plate and the second conductive terminal plate penetrate through the casing.

Abstract: An electrochemical method for manufacturing a lithium phosphate (Li3PO4) thin film includes preparing an electroplating solution and forming the lithium phosphate thin film on a conductive substrate under suitable conditions. The electroplating bath includes about 10?2M to about 10?1M lithium ion and about 10?2 M to about 1 M monohydrogen phosphate ion (HPO42?) or dihydrogen phosphate ion (H2PO4?).
