Description
本実施の形態では、本発明の一態様の負極について、図面を参照して説明する。
図1に、以下で例示する負極100の断面構成例を示す。負極100は、集電体101の表面上に負極活物質層102と、負極活物質層102を覆う被覆層110とを有する。負極活物質層102は、負極活物質111と、バインダ112と、を有する。また図1に示すように、負極活物質層102は、導電助剤113と、金属フレーク114と、を有していてもよい。
続いて、被覆層110を設けることにより、負極の劣化を抑制される理由について説明する。
以下では、本発明の一態様の負極の作製方法の一例について、図6を用いて説明する。図6は、以下で例示する作製方法例に係るフローチャートである。
[コイン型蓄電池]
図7(A)は、コイン型(単層偏平型)の蓄電池の外観図であり、図7(B)は、その断面図である。
次に、円筒型の蓄電池の一例について、図8を参照して説明する。円筒型の蓄電池600は図8(A)に示すように、上面に正極キャップ(電池蓋)601を有し、側面及び底面に電池缶(外装缶)602を有している。これら正極キャップと電池缶(外装缶)602とは、ガスケット(絶縁パッキン)610によって絶縁されている。
次に、ラミネート型の蓄電池の一例について、図9(A)を参照して説明する。ラミネート型の蓄電池は、可撓性を有する構成とすれば、可撓性を有する部位を少なくとも一部有する電子機器に実装すれば、電子機器の変形に合わせて蓄電池も曲げることもできる。
粉末状のガリウム、銅フレーク、VGCF、及び樹脂(PVDF)を、それぞれ重量比が85:5:5:5となるように混合させた。この混合物を遊星型混練機で2000rpmの条件で5分間混練した後、NMP(N−メチルピロリドン)を添加し、さらに15分混練して第1のスラリーを作製した。その後、集電体である銅を主成分として含む金属箔上に、第1のスラリーを塗工し、50℃の条件で2時間保持して溶媒を気化させた後、120℃の条件で10時間保持した。
作製した実施例試料及び比較試料について、断面SEM観察を行った。図17(A)は実施例試料の断面観察像であり、図17(B)は比較試料の断面観察像である。
続いて、上記実施例試料と比較試料を用いたハーフセルを作製し、活物質にキャリアイオンを挿入した直後と、さらにキャリアイオンを脱離させた後とで、それぞれ電極表面のSEM観察を行った。
続いて、実施例試料及び比較試料を負極に用いたフルセルを作製し、充放電サイクル特性を評価した。
以上のことから、リチウムイオン電池の充放電の繰り返しにおいて、ガリウムと銅を合金化させることで、リチウムイオン電池のサイクル特性を向上させることができた。
