Abstract: The present invention is related to a novel positive electrode active material for lithium-ion battery. The positive electrode active material is expressed by the following formula: Li1.2NixMn0.8-x-yZnyO2, wherein x and y satisfy 0<x?0.8 and 0<y?0.1. In addition, the present invention provides a method of manufacturing the positive electrode active material. The present invention further provides a lithium-ion battery which uses said positive electrode active material.

Abstract: An integrated method for uploading data on a blockchain comprising: receiving an editable text data or an editable form data by the data source computer device; determining whether a file update time of the editable text data or the editable form data is later than a last change time stored by the service server and corresponding to the data by the data source computer device; sending the data to the service server when the data source computer device determined that the file update time is later than the last change time by the data source computer device; executing a corresponding service that is able to access data of a blockchain and upload the data to the blockchain according to the data from the data source computer device by the service server. Therefore, the data can be efficiently and quickly uploaded to the blockchain.
