X—Ra—Rb In Chemical Formula 1, X is an active material which comprises a metal and has a functional group which has been reacted with a silane coupling agent, Ra is a residual group from a silane coupling agent, and Rb is a polymer.

Abstract: Disclosed are a binder composition for a rechargeable lithium battery including a cross-linked compound of polyacrylic acid substituted with an alkali cation and polyvinyl alcohol and an electrode and rechargeable lithium battery including the same. The cross-linked compound of polyacrylic acid and polyvinyl alcohol is obtained by heating polyacrylic acid and polyvinyl alcohol to effect a cross-linking reaction via esterification. The cross-linked compound of polyvinyl alcohol and polyacrylic acid substituted with an alkali cation may improve phase stability of a binder, and has high cross-linking ratio, thereby providing for excellent performance of a rechargeable lithium battery.

Abstract: A rechargeable battery including an electrode assembly that includes a positive electrode and a negative electrode and a separator and is configured of any one of a winding type and a stacking type and a case receiving the electrode assembly together with an electrolyte solution. A positive electrode includes a positive current collector and a negative electrode includes a negative current collector. At least one of a positive current collector and a negative current collector is positioned at a base layer to which an active material is applied and protruding portions that are positioned at one end of the base layer and are formed at a larger thickness than the base layer to surface-contact each other at the wound or stacked electrode assembly.

Abstract: An electrode assembly according to an exemplary embodiment of the present invention comprises: a first electrode which includes a first electrode current collector and a first electrode active material layer formed on the first electrode current collector; a second electrode which includes a second electrode current collector and a second electrode active material layer formed on the second electrode current collector; and a separator disposed between the first electrode and the second electrode. A supporting portion is formed of a groove or a protrusion at an edge of the first electrode current collector, and a combination portion is combined with the supporting portion on the first electrode active material layer.

Abstract: A servo controller for a disk drive controller comprising a storage device that stores communication information for a plurality of devices and a serial port controller located on the servo controller that communicates with the storage device, that receives a request to communicate with one of the plurality of devices, and that allows communication between at least one processor and the one of the plurality of devices according to the stored communication information and the request, wherein each of the plurality of devices uses a different protocol.

Abstract: A method and system for transferring control information between a host and network processor is provided. The system includes, a snooping module that is coupled to a snooping memory bus; a network cache controller; a host process scheduler that communicates with the network cache controller; and a host cache controller that controls a host cache for transferring control information without polling. The method includes, invalidating a data block in a network cache, after a message is composed by the host processor; invalidating a status block in the network cache after the message is posted; and transferring control from the host processor to the network processor. The method also includes, invalidating a status segment in a network cache after data is transferred from a host cache to a network cache; and invalidating a status segment in the host cache after data has been injected to a network.

Abstract: A serial port controller in an embedded disk drive controller is provided. The serial port controller includes a state machine that can access protocol information regarding plural devices operationally coupled to the serial port controller; a first register that can hold address information of the plural devices; and logic for enabling the plural devices for either a write or read request. The serial port controller also includes a second register for holding write data information for the plural devices; and a third register for holding read data information for the plural devices. The serial port controller reads programmed information regarding the plural device upon a client request; transmits the address of a device with whom communication is requested by the client; and transmits data to the plural devices, if the request by the client is to write data or collects data for a read request.
