Abstract: A stacking device may include a negative delivery structure, a separator delivery structure, a first heater and a positive delivery structure. The negative delivery structure may be configured to deliver a negative electrode sheet. The separator delivery structure may be configured to deliver separators to two sides of the negative electrode sheet such that the separators are attached to the negative electrode sheet. The first heater may be arranged downstream of the separator delivery structure and configured to heat the negative electrode sheet and the separators. The positive delivery structure may be arranged downstream of the first heater and configured to deliver positive electrode sheets to the two sides of the negative electrode sheet such that the positive electrode sheets are attached to the separators.

Abstract: A data writing request is received at a web browser from a first application, where the data writing request comprises data and address information of a web page into which the data is written, and where the web browser and the first application are associated with a mobile device. The data writing request is sent to a web server. An instruction message is received from the web server and the data is stored at a shared storage space on the mobile device based on the instruction message. A data access request is received from a second application, where the web browser and the second application are associated with the mobile device. The data is read from the shared storage space based on the access request and sent to the second application.
