Abstract: A vehicle battery control apparatus which includes a memory and a controller. For example, the vehicle battery control apparatus obtains at least one of driving durability data according to a driving state of a host vehicle or calendar aging data according to a parking state of the host vehicle, or any combination thereof, obtains degradation data of a battery of the host vehicle using at least some of the driving durability data or the calendar aging data, or the any combination thereof, and compares reference data identified based on a predetermined reference model with the degradation data to determine a degradation state of the battery.

Abstract: A non-contact interface device for a vehicle and a method for controlling the same, may display an operation system menu for a driver and passengers to operate various kinds of devices of the vehicle as a hologram, enable a user to operate the displayed operation system menu in a non-contact manner by use of the user's finger or the like, and provide the user with a tactile feedback for a non-contact operation, so that the user can recognize whether to have operated the menu.

Abstract: Disclosed is a silicon-carbon composite negative-electrode active material for a lithium secondary battery having improved electrochemical properties which contains a carbon material derived from a wood-based material and a compound containing an isocyanate functional group in order to improve unstable dispersibility of silicon-based particles used as a negative-electrode active material for a lithium secondary battery, thereby improving electrical conductivity and producing stable electrode slurry. Further, a method for producing the same, and a lithium secondary battery including the same are disclosed.

Abstract: The present invention relates to a lithium-sulfur ultracapacitor including a cathode containing a sulfur-porous carbon composite material; a separator; a lithium metal electrode disposed on an opposite side of the cathode with respect to the separator; a graphite-based electrode disposed adjacent to the lithium metal electrode; and an electrolyte impregnating the cathode, the lithium metal electrode, and the graphite-based electrode, wherein the lithium metal electrode and the graphite-based electrode together constitute an anode, and a method of preparing the lithium-sulfur ultracapacitor.

Abstract: DRAM and SRAM devices have a NAND interface mode (pins whose address and data are identical to one another are commonly used), directly being coupled to buses (an address/data bus and a control bus) of a NAND-type flash memory device that is connected to a microprocessor. Upon such a common interface mode, a DRAM device, an SRAM device, a NAND-type flash memory device, and a NOR-type flash memory device have the identical interface mode, and are independently (or individually) controlled by only one memory controller.
