LiaNibCocMnd1 O 2
(化学式2で、0.90≦a≦1.2、0.5≦b≦0.9、0<c<0.4、0<d1<0.4である。)
[化学式3]
LiaCoO2
(化学式3で、0.90≦a≦1.2である。)
LiaNibCocMnd1 O 2
化学式2で、0.90≦a≦1.2、0.5≦b≦0.9、0<c<0.4、0<d1<0.4である。
また、化学式2の化合物を正極活物質として用いると安全性と寿命を確保することはできるが、電池に適用する場合、正極の合剤密度が低いため、実際に得られる容量は期待したほど大きくない問題点があるので、これを防止するために、化学式2の化合物を第1正極活物質とし、下記化学式3の化合物を第2正極活物質として、両者を混合使用した。
LiaCoO 2
前記化学式3で、0.90≦a≦1.2である。
合剤密度とは、極板より集電体を除いた成分(つまり、活物質、導電材、及びバインダーなど)の単位体積当たり質量値であって、合剤密度が小さいということは、単位体積当り(極板の面積が同一であるとすれば単位厚さ当り)の装着活物質量が少ないので、結果的に実際の電池容量は減少することを意味する。つまり、本発明で第1正極活物質として用いた化学式1又は化学式2の化合物は、理論容量は高いが、実際の電池に適用すると合剤密度が低く、実際の電池容量はLiCoO2に相応する値を示すため、容量面での長所を得られなくなる。
第1正極活物質としてLiNi0.8Mn0.2O2又はLiNi0.8Co0.1Mn0.1O2、第2正極活物質としてLiCoO2を使用し、下記表3に示した組成で混合して混合正極活物質を製造した。この混合正極活物質とポリフッ化ビニリデンバインダー及びスーパー−P導電材を、N−メチルピロリドン混合溶媒中で94/3/3(質量比)の組成比で正極活物質スラリーを製造した。前記スラリーをアルミニウム集電体にコーティングして、これを乾燥し、圧延して正極を製造した。
下記表1〜3に示したように、第1正極活物質としてLiCoO2、LiNiO2、LiNi0.8Co0.2O2又はLiNi0.8Mn0.2O2を使用し、第2正極活物質としてLiMn2O4又はLiCoO2を用いたことを除いては、前記実施例1と同一な方法で正極を製造した。
製造された電池を0.2Cに充電し、0.2Cに放電を1回実施し(化成工程)、0.5C充電、0.2C放電を1回実施した(標準工程)。標準工程1回目の放電量を測定して、下記表1〜3に容量として示した。
上記実施例12の電池を化成及び標準評価を実施した後に解体して、正極板のSEM−EDX分析を実施した。電池組立前とは異なって、組立後(電池評価)には極板の構造(縁部あるいは折れた部分)に沿って極板の表面特性が変化する可能性があるので、電池を解体した後に図2のように極板をサンプリングした。
