Abstract

<P>PROBLEM TO BE SOLVED: To provide a system capable of making electrode materials (positive electrode and negative electrode) of a lithium ion secondary battery into simple substances. <P>SOLUTION: An active material side of the electrode material wherein a metal foil and an active material are integrated with each other is scraped off with a rotating edged tool. By heating the edged tool at temperature of 50-450°C, the active material can be scraped easily since the active material is softened, and the metal foil can not be shaved. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

発明の詳細な説明Detailed Description of the Invention

本発明は、リチウムイオン二次電池の電極材、正極は［アルミ箔＋コバルト系物質］、負極は［銅箔＋カーボン等］で構成されている各々２種類の物質を剥がし、材料であるアルミ、コバルト系物質、銅、カーボン等の４種に分離し、材料を再利用可能とする装置。  In the present invention, the electrode material of the lithium ion secondary battery, the positive electrode is made of [aluminum foil + cobalt material], and the negative electrode is made of [copper foil + carbon, etc.], each of two kinds of materials are peeled off to form aluminum as a material. , A device that separates the material into four types, such as cobalt-based material, copper, and carbon, and makes the material reusable.

従来は、薬品にて溶かして抽出しており、廃液などの問題が発生しています。また、焼却処分をしている場合もあり大量のＣｏ２発生となっています。  Conventionally, it has been extracted by dissolving with chemicals, causing problems such as waste liquid. In addition, incineration disposal may cause a large amount of Co2.

本発明は、以上の問題点を解決できます。
銅箔、アルミ箔を金属箔と以後表現。コバルト系物質とカーボン等を活性物質と以後表現する。金属箔と活性物質が一体となった電極材の活性物質側を、回転する刃物で削ぎ落とす。刃物の温度を５０度以上４５０度以下に加熱する事で、活性物質は軟化し容易に削れ金属箔は削られない。回転する刃物は、円柱状もしくは円筒状の金属に、その円周の接線の接点に対して直角に、複数の平たい刃物を並行に並べた物である。The present invention can solve the above problems.
Hereinafter, copper foil and aluminum foil are expressed as metal foil. Cobalt-based materials and carbon are hereinafter expressed as active materials. The active material side of the electrode material in which the metal foil and the active material are integrated is scraped off with a rotating blade. By heating the temperature of the blade to 50 degrees or more and 450 degrees or less, the active substance is softened and easily cut, and the metal foil is not cut. A rotating blade is a tool in which a plurality of flat blades are arranged in parallel on a columnar or cylindrical metal at a right angle to a contact point of a circumferential tangent.

本発明は［０００１］［０００２］［０００３］で説明したように、金属箔と活性物質が一体となった電極材の活性物質側を、回転する刃物で削ぎ落とす装置です。  As described in [0001] [0002] [0003], the present invention is a device that scrapes off the active material side of the electrode material in which the metal foil and the active material are integrated with a rotating blade.
