Abstract: A lithium battery includes a positive electrode plate, a negative electrode plate, a separator located between the positive electrode plate and the negative electrode plate, and an electrolyte solution. The negative electrode material layer of the negative electrode plate includes a lithium-silicon composite negative electrode active material. The negative electrode material layer has a protective layer on the surface or the lithium-silicon composite negative electrode active material has a protective layer on the surface. The protective layer includes a polymer matrix and a lithium salt. When the lithium battery is fully charged, the lithium-silicon composite negative electrode active material includes elemental lithium and a lithium-silicon alloy Li4.4Si, and the elemental lithium accounts for 15%-95% by mole of the lithium-silicon composite negative electrode active material.

Abstract: A multi-procedure integrated automatic production line for hard alloy blades under robot control is provided. The production line includes a rail-guided robot. A cutter passivation device and a blade cleaning and drying device are arranged on one side of the rail-guided robot. A blade-coating transfer table, a blade coating device, a blade boxing transfer table, a blade-tooling dismounting device and a blade boxing device are sequentially arranged on another side of the rail-guided robot. The blade-tooling dismounting device is arranged on one side of the blade boxing transfer table. The production line further includes squirrel-cage toolings for carrying the blades. The squirrel-cage tooling that are loaded with the blades can run among the cutter passivation device, the blade cleaning and drying device, the blade-coating transfer table and the blade boxing transfer table. The blades after being treated through the blade-tooling dismounting device are sent to the blade boxing device.

Abstract: The present invention relates to a powder dry-pressing molding device and method.

Abstract: An example for determining consensus by Parallel Proof of Voting (PPoV) in a consortium blockchain includes causing each bookkeeping node to generate and publish a block to a consortium blockchain network. After collecting all the block generated in the previous step, the consortium node votes send a total voting message (the hash value of each block, as well as the agreed opinion and signature) to the leader node. The leader node counts the voting results and random selects the next leader node, which publishes the block group header to the consortium blockchain network. When a blockchain node receives the block generated by the bookkeeping nodes and the block group header generated by the leader node, it will store them in the database as a block group.

Abstract: The invention relates to a blockchain-based domain name resolution system, characterized in that the domain name resolution system adopts a layered structure comprising a top-level domain name chain network, a second-level domain name chain network, a future network node and an existing DNS system network; the top-level domain name chain network links the second-level domain name chain network, the future network node and the existing DNS system network respectively, and the top-level domain name chain network is used for each professional organization to deploy the server nodes having a reliable performance respectively to form a union blockchain network, wherein each node server records the information of all the current top-level domain names, the second-level domain name chain nodes, the future network nodes and the root nodes of the existing DNS system; the second-level domain name chain network is used for the registration and management of domain names, and recording of all the second-level domain name

Abstract: A method comprising: In some implementations, a method for indexing a multi-layer blockchain system, comprising: A. using, a top layer blockchain, to index a lower layer blockchain by recording a seed node in a transaction log of a block; B. requesting a distributed monitoring cluster to periodically check availabilities of IP addresses and ports that listed in the seed node stored in the top layer blockchain; C. maintaining, for each node in the lower layer blockchain, a separate instance of a global routing table. Each global routing table store entire topological structure of the multi-layer blockchain system, and final consistency of the global routing tables is maintained through a GOSSIP-based data communication protocol. Any node located on the lower layer blockchain described in Step C is configured to access data and services through any one of accessible nodes identified by IP addresses and ports recorded in the global routing table.
