  • Patent number: 11283101
    Abstract: A method of preparing an electrode for an electrode assembly having a structure in which electrodes are laminated, including: (i) a process of coating an electrode mixture on at least one surface of a metal sheet so that n (n?2) electrode mixture coated layer lines are formed between non-coated portions parallel to a first direction; (ii) a process of rolling the metal sheet sequentially from a first electrode mixture coated layer line to an nth electrode mixture coated layer line using a rolling roller rotated in a second direction perpendicular to the first direction; (iii) a process of slitting the rolled metal sheet at least twice in the second direction to prepare electrode plate base materials having n electrode mixture coated layers formed thereon; and (iv) a process of cutting each of the electrode plate base materials in the first direction to obtain n single sheet electrodes.

  • Patent number: 11114652
    Abstract: The present invention discloses a method of manufacturing an electrode for a secondary battery by using a single process to notch and cut a unit electrode from an electrode sheet. The method for manufacturing electrodes for a secondary battery includes supplying an electrode sheet in a moving direction (MD), wherein the electrode sheet has a plurality of coated portions and uncoated portions alternately arranged along the MD, wherein each coated portion has an electrode active material, and each uncoated portion does not have an electrode active material; and cutting the uncoated portions to form the plurality of unit electrodes.

  • Patent number: 10319329
    Abstract: The present invention attenuates noise appearing at neighboring electrodes by causing a rising edge of one clock signal to be synchronized with a falling edge of another one clock signal when a clock signal for gate driving is generated.
