Description
また、前記負極は、前記固溶体100重量部に対して、炭素材料を5〜50重量部含んでいることが好ましい。
ここで、0≦x<10であり、デンドライトを効果的に抑制する観点からは、0≦x<5であることが好ましい。
また、z=1である。なお、xの値は、電池の充放電反応によるLiの吸蔵・放出により変化する。電池の製造直後には、xは、一般に0である。
負極活物質(固溶体)の粉末8.5g、導電剤として黒鉛粉末1gおよび結着剤としてポリエチレン粉末0.5gを混合して合剤とした。この合剤0.1gを直径17.5mmの円板状に加圧成型して試験電極1とした。次いで、試験電極1を図1に示すようにケース2の中に置いた。そして、その上に微孔性ポリプロピレンのセパレータ3を置いた。次いで、ケース2の中に非水電解液を注いだ。ここでは、1モル/リットルとなるように過塩素酸リチウム(LiClO4)をエチレンカーボネートおよびジメトキシエタンの等体積比の混合物に溶解してなる電解液を用いた。そして、内側に直径17.5mmの円板状の金属リチウム4が張り付けられ、外周部にポリプロピレンのガスケット5を付した封口板6でケース2を封口し、試験セルとした。
負極活物質(固溶体)、導電剤として黒鉛粉末および結着剤としてポリ4フッ化エチレンを重量比で60:30:10の割合で混合した。そして、これに石油系溶剤を加えてペーストにした。得られたペーストを銅の芯材に塗布し、100℃で乾燥し、負極板とした。
M 1 y M 2 z (M 1 x M 2 y は、前記群より選ばれる少なくとも1種)で示される組成を有し、M1の結晶構造にM2が溶け込んだ、またはM2の結晶構造にM1が溶け込んだ固溶体を以下の手順で調製した。そして、これを負極活物質として用い、上述した試験セルおよび円筒形電池を組み立て、その評価を行った。
従来報告されているFe−Sn系金属間化合物(J.R.Dahnら、Journal of Electrochemical Society、146(2)414−422(1999))を活物質として用いたこと以外は、前記実施例と同様の操作を行い、同様の評価を行った。
