Abstract
With a method of manufacturing a secondary battery electrode having active material (111) on a current collector (110), a computer (100) acquires a deposition pattern (PT) for depositing a plurality of kinds of active materials, different in electrical characteristic, onto discrete areas of a current collector, and the computer allows injection nozzles (108) to inject the plurality of kinds of active materials onto the current collector as multiple particles (P), respectively, to be deposited thereon, thereby forming an active material layer.
Claims20
A method of manufacturing a secondary battery electrode having active materials on a current collector, comprising:
- letting a computer acquire a deposition pattern for depositing a plurality of kinds of active materials, different in electric characteristic, onto discrete areas of a current collector, respectively;
- and
- letting the computer allow injection nozzles to inject the plurality of kinds of active materials, as multiple particles, onto the current collector for deposition thereon, respectively, in accordance with the deposition pattern for thereby forming an active material layer.
The method according to clam 1, wherein the active material layer is formed by drying the plurality of kinds of active materials deposited onto the current collector.
The method according to clam 1, wherein the computer accesses to a memory device to read the deposition pattern stored therein for thereby acquiring the deposition pattern.
The method according to clam 3, wherein the computer is used and draws the deposition pattern on a display whereupon the deposition pattern drawn on the display is stored in the memory device to allow the computer to read the deposition pattern stored in the memory device for thereby acquiring the deposition pattern.
The method according to clam 1, wherein the deposition pattern allows the plurality of kinds of active materials to be located on the discrete areas of the current collector, respectively.
The method according to clam 1, wherein the deposition pattern allows the plurality of kinds of active materials to be regularly and periodically located on the discrete areas of the current collector, respectively, in an individual fashion.
An apparatus for manufacturing a secondary battery electrode having active materials on a current collector, comprising:
- a computer generating a deposition pattern for depositing a plurality of kinds of active materials, different in electric characteristic, onto discrete areas of a current collector, respectively;
- a memory device storing the deposition pattern generated by the computer;
- injection nozzles injecting the plurality of kinds of active materials, as multiple particles, onto the current collector, respectively, in accordance with the deposition pattern stored in the memory device;
- and
- a heater drying the plurality of kinds of active materials deposited on the current collector, respectively.
A secondary battery electrode comprising:
- a current collector;
- and
- an electrode layer formed on the current collector and including a plurality of kinds of active materials, different in electrical characteristic, the electrode layer being structured such that graphics associated with the plurality of kinds of active materials, respectively, are located on discrete areas of the current collector.
