Electrode, Rechargeable Battery And Fablicating Method Of Electrode

Abstract

According to one aspect of the present invention, an electrode used for a rechargeable battery is applied to a positive electrode of a negative electrode of the rechargeable battery, wherein the electrode can comprise a sheet-shaped current collector and an active material layer coated on the current collector, and rags processed by laser are formed at the side end of the current collector.

Description

technical field [0001] The described technology relates generally to electrodes for rechargeable batteries, rechargeable batteries, and methods of making the electrodes, and more particularly to electrodes, rechargeable batteries, and methods of making the electrodes in which the structure of the cut surfaces of the electrodes is improved. Background technique [0002] Unlike primary batteries, rechargeable batteries are batteries that can be charged and discharged. Small-capacity rechargeable batteries are used for small portable electronic devices such as mobile phones, notebook computers, camcorders, etc., while large-capacity rechargeable batteries are used as power sources for drive motors of hybrid vehicles and the like. [0003] Recently, a high-output and large-capacity rechargeable battery using an anhydrous electrolyte and having a high energy density has been developed, and a plurality of the above-mentioned high-output rechargeable batteries are connected in seri...

Problems solved by technology

Coated parts are unlikely to short circuit because the burrs are buried in the active material, but uncoated parts can short circuit to adjacent electrodes if the burrs pass through the separator
