An electrode sheet having a current collector coated with electrode depolarizing mix on both upper and lower surfaces of the current collector, wherein: the electrode sheet has a portion of the current collector not coated with the electrode depolarizing mix; and the electrode depolarizing mix coated ends on both the upper and lower surfaces of the current collector are shifted by 0.3 mm or longer and 30 mm or shorter in a longitudinal direction of the electrode sheet.

Cell electrode sheet with displaced electrode depolarizing mixes

A cell electrode of a stripe rectangle shape having at least one electrode depolarizing mix layer on a current collector. A thickness of one end portion of the electrode depolarizing mix layer is thicker than an average thickness of the electrode depolarizing mix layer by 2 to 25%.

Cell electrode with thick tip portion

A method of making a cell electrode of a stripe rectangle shape having at least one electrode depolarizing mix layer on a current collector. A thickness of one end portion of the electrode depolarizing mix layer is thicker than an average thickness of the electrode depolarizing mix layer by 2 to 25%. The method comprises sequentially bond adhesive tape pieces to a strip conductive sheet, coating on electrode depolarizing mix solution on the surface of the stripe conductive sheet and peeling off the adhesive tape piece.

Method of making cell electrode with thick tip portion

A cell electrode of a stripe rectangle shape having at least one electrode depolarizing mix layer on a current collector. The thickness of two end portions of the electrode depolarizing mix layer are thicker than an average thickness of the electrode depolarizing mix layer by 2 to 25%.

Cell electrode with thick tip portions

A method for producing an electrode sheet having a multilayer structure is disclosed, wherein two or more layers for an electrode sheet are simultaneously coated with a coating solution by using a coater.

Producing electrode sheet with multilayer structure by simultaneous

In producing an electrochemical battery constituted by a positive electrode, a negative electrode and an electrolytic solution, an electrode material coating composition is discharged from an extrusion type liquid injector having a slot, and applied while at least one uncoated portion is being provided on a running conductive support in the running direction, so as to produce a sheet electrode plate.

Method of producing a sheet electrode plate for electrochemical battery

There is disclosed a method for producing a sheet-like electric cell plate and an electrochemical cell produced by using the plate. The sheet-like electric cell plate is produced by a method which comprises discharging an electrode material coating solution from an extrusion-type slot die and coating the solution onto an electrically-conductive support running around a backup roll. The electrochemical cell comprises a positive electrode plate, a negative electrode plate, both of which plates are produced by the above method, and an electrolyte.

Method for producing a sheet-like plate

A method and apparatus for applying a magnetic liquid to a moving web by using an extruder head for ejecting the magnetic liquid onto the web. A by-pass line for returning the liquid to a feed source through a changeover valve is provided immediately upstream to the extruder head. The liquid is supplied to the by-pass line through the valve after the extruder head is filled with the liquid before the first starting of the application or the resumption thereof. The position of the valve is shifted at the time of the first starting of the application or the resumption thereof so as to supply the liquid to the head to perform the application.

Magnetic liquid application method and apparatus

A coating method and apparatus using an extrusion head to apply a liquid film to a running web. The thickness of the film is measured at two transverse points and a roller conveying the web is tilted to correct any difference. The amount of tilt per roller with a roller bearing span of 750 mm is 0.5 to 20 mm, preferably 0.5 to 15 mm.
