摘要： An anode for an energy storage device includes a current collector having a metal oxide layer. A continuous porous lithium storage layer overlays the metal oxide layer, and a first supplemental layer overlays the continuous porous lithium storage layer. The first supplemental layer includes silicon nitride, silicon dioxide, or silicon oxynitride. The anode may further include a second supplemental layer overlaying the first supplemental layer. The second supplemental layer has a composition different from the first supplemental layer and may include silicon dioxide, silicon nitride, silicon oxynitride, or a metal compound.

摘要： Provided is an agent for dispersing an electrically conductive carbon material, in which the agent consists of a polymer which has an oxazoline group in a side chain and which is obtained by using an oxazoline group-containing monomer such as that represented by formula (1) for example, and in which the agent exhibits excellent dispersion of an electrically conductive carbon material and produces a thin film that exhibits excellent adhesion to a current collection substrate when formed into a thin film together with the electrically conductive carbon material. (In the formula, X denotes a polymerizable carbon-carbon double bond-containing group, and R1-R4 each independently denote a hydrogen atom, a halogen atom, an alkyl group optionally having a branched structure having 1-5 carbon atoms, an aryl group having 6-20 carbon atoms, or an aralkyl group having 7-20 carbon atoms.)

摘要： This undercoat foil for an energy storage device electrode comprises a collector base plate, and an undercoat layer formed on at least one surface of the collector base plate, the undercoat layer containing carbon nanotubes, and the coating amount per collector base plate surface being 0.1 g/m2 or less. Since this undercoat foil can be effectively welded by ultrasound, the use thereof allows a low-resistance energy storage device and a simple and effective production method therefor to be provided.
