Abstract:
The objective of the present invention is to provide a lithium ion battery using a mixed conductive material which: promotes a battery reaction by mixing the mixed conductive material, capable of transferring electrons and lithium ions at the same time, with an active material; effectively transfers electrons as byproducts formed by the battery reaction to a current collector; and thus can extend the lifespan of the battery and enhance output characteristics of the battery. The present invention provides the lithium ion battery using a mixed conductive material which includes: a cathode comprising cathode laminated materials; an anode comprising anode laminated materials; and an electrolyte which separates the cathode and the anode. The cathode laminated materials and the anode laminated materials include the mixed conductive material capable of transferring electrons and lithium ions at the same time.

PURPOSE: An image display apparatus for a vehicle using a digital micro-mirror device is provided to generates virtual images imaged by an imaging module in the specific window glass side through projecting the images to the specific window glass direction. CONSTITUTION: An image display apparatus for a vehicle using a digital micro-mirror device comprises a light source(10), a digital micro mirror device(20), a first reflection module(30), an imaging module(40), a second reflection module(50). The digital micro mirror device generates images and exits the generated images to the outside through light. The first reflection module reflects the images exited by the digital micro mirror device. The imaging module images the reflected image from the first reflection module. The second reflection module projects the imaged images to the direction of a specific window glass of a vehicle and generates the virtual images in the specific window glass side.
