Description
前記第2極の活物質は、酸化されてマグネシウムイオン、アルミニウムイオン、又は カルシウムイオンのいずれかの金属イオンを生成し、
前記第1極の活物質は、スカンジウム(Sc)、チタン(Ti)、バナジウム(V)、 クロム(Cr)、マンガン(Mn)、鉄(Fe)、コバルト(Co)、ニッケル(Ni)、 銅(Cu)及び亜鉛(Zn)からなる群より選ばれた少なくとも1種の金属元素のハロゲ ン化物であり、
前記金属イオンを前記第1極に吸蔵する
ように構成されていることを特徴とする、電気化学デバイスに係るものである。
前記第2極の活物質は、酸化されてマグネシウムイオン、アルミニウムイオン、又は カルシウムイオンのいずれかの金属イオンを生成し、
前記第1極の活物質は、スカンジウム(Sc)、チタン(Ti)、バナジウム(V)、 クロム(Cr)、マンガン(Mn)、鉄(Fe)、コバルト(Co)、ニッケル(Ni)、 銅(Cu)及び亜鉛(Zn)からなる群より選ばれた少なくとも1種の金属元素のハロゲ ン化物であり、
前記金属イオンを前記第1極に吸蔵するように構成されているので、例えば電池として構成されたときに、優れた特性を実現することができる。
負極:Mg → Mg2+ + 2e-
に従って、負極活物質であるマグネシウム、アルミニウム、又はカルシウムの金属単体、或いはその合金が酸化され、負極集電体7を通じて外部回路に電子を放出する。この反応で生じた、前記金属イオンであるマグネシウムイオン、アルミニウムイオン、又はカルシウムイオンは、電解液4中に溶け出し、電解液4中を拡散して、正極1側へ移動する。
正極:Mg2+ + CoCl2 + 2e- → MgCl2 + Co
などの反応が起こり、マグネシウムイオンなどの金属イオンが安定に吸蔵され、Co2+などの前記金属元素の陽イオンが還元され、正極集電網5および正極集電体6を通じて外部回路から電子を取り込む。
負極活物質として金属マグネシウムを用い、正極活物質として塩化コバルト(II)(CoCl2)を用いて、図1に示したコイン型のマグネシウム二次電池10を作製した。
塩化コバルト(II)(CoCl2;アルドリッチ社製)を乳鉢で粉砕し、粒径の小さなグラファイト(ティムカルジャパン社製、商品名:KS6、平均粒径6μm)をカーボン導電材料として加え、十分に混合した。塩化コバルト(II)とKS6の質量比は1:1とした。この混合物をステンレス鋼(SAS)製の正極集電網5に圧着して、ペレット状の正極1を作製した。
上記の正極1と金属マグネシウム板からなる負極2とを、ポリエチレングリコールからなるセパレータ3を間に挟んで、直接接触しないように配置し、ステンレス鋼(SAS)製の正極集電体6および負極集電体7で囲まれた電池室8に電解液4を充填して、二次電池10を作製した。電解液4としては、Mg(ACl2EtBu)2のテトラヒドロフラン(THF)溶液を濃度0.25mol/lに調製したものを用い、正極側および負極側に、それぞれ75μLずつ、合計で150μLを充填した。
上記で作製した二次電池10の充放電特性を室温で測定した。放電時は0.5mAの一定電流で0.2Vになるまで行い、充電時は0.5mAの一定電流で充電し、2Vに達したら2Vの一定電圧で0.1mAの充電電流になるまで行った。測定は放電から開始した。なお、作製直後の電池は、開回路状態で放置しても自己放電はなく、電圧も安定していることを確認した。
二次電池10を用いて、サイクリックボルタンメトリ(CV)測定を室温で行った。測定は、0.1mV/sおよび1mV/sの条件下で、それぞれ、開回路状態(OCV)→0.2V→2.0V→OCVの変化を2周ずつ行った。測定を2.0V以上で行わないのは、本実施例で用いた電解液が分解してしまう可能性があるためである。
図4は、他の塩化物を正極活物質として用いて作製したマグネシウム二次電池10の放電特性の測定結果を示すグラフである。図4には、比較のため、実施例1のCoCl2の測定結果も示している。用いた材料は、CuCl、CuCl2、NiCl2、FeCl2、FeCl3、CrCl2、MnCl2である。実施例2で用いた材料はすべてアルドリッチ社製のもので、電池の作成方法および測定方法は、実施例1と同じである。図4から、多くの塩化物材料がマグネシウム二次電池の正極活物質として使用可能であることがわかるが、特に、NiCl2、CoCl2、FeCl2、CrCl2、およびCuCl2が好ましい。これは、より大きな電流容量が得られるためである。
以上、本発明を実施の形態及び実施例について説明したが、上述の例は、本発明の技術的思想に基づき種々に変形が可能である。
