Description
非水電解質二次電池1は、図1〜図4に示される容器10と、図2〜図5に示される電極体20とを有する。非水電解質二次電池1は、容器10が略直方体状である角形の非水電解質二次電池である。
られる。コバルト、ニッケル及びマンガンのうちの少なくとも一種を含むリチウム酸化物の具体例としては、リチウム含有ニッケルコバルトマンガン複合酸化物(LiNixCoyMnzO2、x+y+z=1、0≦x≦1、0≦y≦1、0≦z≦1)、コバルト酸リチウム(LiCoO2)、マンガン酸リチウム(LiMn2O4)、ニッケル酸リチウム(LiNiO2)、またはこれらの酸化物に含まれる遷移金属の一部を他の元素で置換した化合物等のリチウム含有遷移金属複合酸化物等が挙げられる。なかでも、リチウム含有ニッケルコバルトマンガン複合酸化物(LiNixCoyMnzO2、x+y+z=1、0≦x≦1、0≦y≦1、0≦z≦1)、またはこれらの酸化物に含まれる遷移金属の一部を他の元素で置換した化合物等のリチウム含有遷移金属複合酸化物が正極活物質としてより好ましく用いられる。正極活物質層21bは、正極活物質に加え、例えば導電材やバインダーなどの他の成分を適宜含んでいてもよい。
る)、リチウムペルフルオロアルキルスルホン酸イミドLiN(CmF2m+1SO2)(CnF2n+1SO2)(式中、m及びnはそれぞれ独立して1〜4の整数である)、リチウムペルフルオロアルキルスルホン酸メチドLiC(CpF2p+1SO2)(CqF2q+1SO2)(CrF2r+1SO2)(式中、p、q及びrはそれぞれ独立して1〜4の整数である)、LiCF3SO3、LiClO4、Li2B10Cl10、及びLi2B12Cl12などが挙げられる。溶質としては、これらの中でも、LiPF6、LiBF4、LiN(CF3SO2)2、LiN(C2F5SO2)2、LiN(CF3SO2)(C4F9SO2)、LiC(CF3SO2)3、LiC(C2F5SO2)3、リチウムビス(オキサレート)ボレート(LiBOB)などのうちの少なくとも一種を含んでいてもよい。なお、LiBOBは、非水電解質二次電池を組み立てた直後において、電解液中に存在していればよい。例えば、組み立て後に充放電を行った後においては、LiBOBは、LiBOBの変成体として存在している場合もある。また、LiBOBまたはLiBOBの変成体の少なくとも一部が負極活物質層上に存在している場合もある。そのような場合も、本発明の技術的範囲に含まれる。
度の高い箇所及び低い箇所があることによって、電池内部に温度のバラツキが存在すると、非水電解質二次電池の電極体が劣化し保存特性が低下する場合がある。
