(1) Layered metal oxides Layered metal oxides are favored by researchers because of their simple manufacturing method and high specific capacity. Similar to lithium batteries, layered oxide cathode materials are also promising cathode materials for commercial use in sodium ion batteries. (2) Prussian blue Prussian blue frame structure allows sodium ions to be embedded and released quickly, with ex...

The theoretical basis and battery structure of sodium ion battery (Na-ion batteries) and lithium ion battery are very similar. Liquid sodium-ion batteries (like solid-state lithium-ion batteries, are also being investigated) are composed of positive electrode, negative electrode, current collector, electrolyte, and battery separator. Among them, electrolyte and separator basically follow the...

After the aluminum laminating film is formed and cut into shape, it is generally called Pocket, as shown in the following figure. In general, when the battery cells is thin, select a single pit (left below), and when the battery cells is thick, select a double pit (right below). Besause when the deformation of aluminum laminate film is too large, it will break through the deformation limit of alum...

The battery cells of the pouch cell battery can be designed into different sizes according to the needs of customers. When the pouch cell case size is well designed, it is necessary to make the corresponding mold to make the aluminum laminate film forming. The pouch cell case forming process is using the forming mold to punch out a pit on the aluminum laminate film that c...

The packaging method of lithium battery depends on the shell material it uses. In general, only lithium pouch batteries will use aluminum laminate film and heat sealing. The metal cans batteries are usually sealed by laser welding. Aluminum laminate film generally has three layers, respectively nylon layer, Al layer, PP layer. Nylon layer is to ensure the appearance of aluminum laminate film,...
