Abstract: Disclosed are an electrode plate and a battery. An electrode plate provided in the present disclosure includes a first current collector and a first functional layer disposed on at least one side of the first current collector, where a plurality of first regions and a plurality of second regions are alternately distributed on a surface of the first functional layer. A content ratio of an element oxygen to an element silicon in the first functional layer within the first region is greater than 4:1. The present disclosure provides the electrode plate and the battery, to at least resolve a problem of low initial efficiency of a lithium-ion battery, and increase battery capacity, thereby improving battery energy density.

Abstract: Disclosed are an electrode plate, a battery cell, and a battery. The electrode plate provided in the present disclosure includes a current collector and an active material layer disposed on at least one surface of the current collector. The active material layer includes active material, the active material includes a silicon-based material, a skeleton layer is provided outside the silicon-based material, and a proportion of a fluorine element gradually increases in a direction from the silicon-based material to the skeleton layer. The electrode plate, the battery cell, and the battery provided in the present disclosure are used to at least solve a technical problem that the battery is prone to volume expansion.

The electrode piece and battery provided by the present application are used for improving initial efficiency and solving the problem of serious expansion of the battery.

Abstract: The present disclosure provides an O-methyltransferase protein with a highly specific catalytic function for multiple benzylisoquinoline alkaloids (BIAs) parent nuclei and an encoding gene and use thereof. Compared with wild-type O-methyltransferase, the O-methyltransferase protein (SEQ ID NO: 2) shows an enhanced enzymatic activity and a wider substrate scope. The O-methyltransferase protein can catalyze O-methylation of backbones from three BIAs, including monobenzylisoquinolines (norcoclaurine, coclaurine, and N-methylcoclaurine), aporphines (asimilobine and N-methylasimilobine), and protoberberines (scoulerine and tetrahydrocolumbamine). Meanwhile, this O-methyltransferase protein is highly regioselective for each backbone. The O-methyltransferase protein catalyzes methylation of the monobenzylisoquinolines at 6-OH and 7-OH, is only active on 6-OH of the backbone of the aporphines, and mainly catalyzes methylation of the protoberberines at 2-OH.

Abstract: Example methods and devices for processing a page are described. One or more pages of a designated website are acquired. The one or more pages are clustered to obtain one or more classes in accordance with page features of the pages. At least one class is selected as a list page set according to a page linking relationship between the one or more classes. It is not necessary to require an operator to manually involve in the process of establishing the list page set. The present techniques have simple operations and high accuracy rate, thereby improving an efficiency and reliability of establishing a list page library.
