Description
実施例1においては、正極を作製するにあたり、上記のLiFePO4からなる正極活物質とリチウムを含有しない金属酸化物であるNiOとを9:1の重量比になるように混合し、この混合物と、導電剤の炭素材料と、結着剤のポリフッ化ビニリデンを溶解させたN−メチル−2−ピロリドン溶液とを、混合物と導電剤と結着剤との重量比が90:5:5になるように混合して、正極合剤スラリーを調製した。そして、この正極合剤スラリーをアルミニウム箔からなる集電体の上に塗布し、これを乾燥させた後、これを圧延ローラーにより圧延し、さらに集電タブを取り付けて正極を作製した。
実施例2においては、正極を作製するにあたり、上記のLiFePO4からなる正極活物質に対して、リチウムを含有しない金属酸化物としてCo3O4を9:1の重量比になるように混合し、それ以外は、上記の実施例1の場合と同様にして正極を作製した。
実施例3においては、正極を作製するにあたり、上記のLiFePO4からなる正極活物質に対して、リチウムを含有しない金属酸化物としてMn2O3を9:1の重量比になるように混合し、それ以外は、上記の実施例1の場合と同様にして正極を作製した。
比較例1においては、正極を作製するにあたり、正極活物質のLiFePO4にリチウムを含有しない金属酸化物を加えないようにし、それ以外は、上記の実施例1の場合と同様にして正極を作製した。
