Abstract:
An electrode coating composition is provided to form mechanically stable thin films and offer good conducting characteristics when the composition is applied onto the surface of a negative electrode. An electrode coating composition includes lithium-supported carbon nanotubes, a non-aqueous electrolyte, a polyfunctional monomer having at least two functional groups, and a hardening initiator. A lithium ion battery(100) includes a negative electrode(10), a positive electrode(20), a separator(30) interposed between the negative electrode and positive electrode, and a non-aqueous electrolyte(40) capable of filling in the space between the positive electrode and negative electrode. The negative electrode includes a negative electrode current collector(12), a negative electrode layer(14) formed on the negative electrode current collector, and a negative electrode coating layer(16) which is applied onto the negative electrode layer and comprises a hardened product of the coating composition.

PURPOSE: A dye sensitized solar cell with a macromolecular film having a mirroring property is provided to easily use light which is thrown out passing through a cell by attaching a macromolecular film with a mirroring property in the back side of a counter electrode. CONSTITUTION: A counter electrode(20) is arranged by facing a working electrode(10). An electrolyte(30) is placed between the working electrode and the counter electrode. A macromolecular film(40) with a mirroring property is attached to the back side of the counter electrode. A metal oxide particle layer(12) is formed on a conductive substrate(11). A dye material is adsorbed in and adhered to the metal oxide particle layer.
Abstract:
A lithium battery electrode by an embodiment of the present invention is capable of including a current collector and an active material layer. The current collector is capable of including a porous polymer layer with a concavo-convex unit, and a metal thin film curved along the concavo-convex unit. The active material layer is located on the upper side of the metal thin film, and is capable of including a nanostructure which is formed of a silicon material. The polymer layer is capable of being treated with plasma for increasing the size of the concavo-convex unit. The capacity properties, coulombic efficiency, and lifetime of the lithium battery electrode are capable of being increased.
