To form a web conveying path that bends and conveys a web, a web conveying device has: a plurality of foil supporting members that are disposed at prescribed intervals in a conveying direction of the web and that support a surface of the web that is being conveyed; a foil extending member stretched between the foil supporting members, which pulls an end of the web downstream in the conveying direction of the web such that the web extends from a starting point to an end point of the web conveying path that is formed by the foil supporting members; and a moving mechanism that moves the foil extending member from the starting point to the end point of the web conveying path.

An electrode manufacturing system includes: a doping unit; a cleaning unit: and a conveyor unit. The doping unit performs a process of doping an active material in a strip-shaped electrode with an alkali metal, the strip-shaped electrode including an active material layer formed portion in which an active material layer including the active material is formed, and an active material layer unformed portion in which the active material layer is not formed. The cleaning unit cleans the active material layer unformed portion that is adjacent to the active material layer formed portion. The conveyor unit conveys the electrode from the doping unit to the cleaning unit.

A novel hybrid lithium-ion anode material based on coaxially coated Si shells on vertically aligned carbon nanofiber (CNF) arrays. The unique cup-stacking graphitic microstructure makes the bare vertically aligned CNF array an effective Li.sup.+ intercalation medium. Highly reversible Li.sup.+ intercalation and extraction were observed at high power rates. More importantly, the highly conductive and mechanically stable CNF core optionally supports a coaxially coated amorphous Si shell which has much higher theoretical specific capacity by forming fully lithiated alloy. Addition of surface effect dominant sites in close proximity to the intercalation medium results in a hybrid device that includes advantages of both batteries and capacitors.
