METHOD FOR MANUFACTURING DOPING TYPE ELECTRODE FOR LITHIUM-BASED POWER STORAGE DEVICE, AND LITHIUM-BASED POWER STORAGE DEVICE

PROBLEM TO BE SOLVED: To dope an electrode active material that a lithium-based power storage device includes, with lithium by a simple and practical manner.SOLUTION: A method for manufacturing a doping type electrode for a lithium-based power storage device comprises the steps of: subdividing lithium of any of various forms, such as bulk, hoop, or powder, easy to determine a quantity thereof into divisions of lithium material 1a with a high quantification accuracy; holding one division of lithium material between and by resin films 2a and 2b and in this state, flattening it into a piece of lithium foil 1b of 50 μm or less in thickness by a roller 3; and putting the piece of lithium foil on an electrode having a predetermined active material to dope the electrode with part or all of lithium in the piece of lithium foil.SELECTED DRAWING: Figure 1 【課題】リチウム系蓄電デバイスが備える電極の活物質に簡便かつ実用的にリチウムをドーピングし得るようにする。【解決手段】バルク状リチウム、フープ状リチウムもしくは粉体状リチウム等の種々の形状の定量し易いリチウムを高い定量精度で小分けし、小分けしたリチウム材１ａを、樹脂フィルム２ａ，２ｂで挟んだ状態でローラ３にて厚さが５０μｍ以下のリチウム箔１ｂに展伸し、所定の活物質を有する電極に貼り付けて、リチウム箔１ｂのリチウムの一部もしくは全部を電極にドーピングする。【選択図】図１
