More Information
Summary:A nonaqueous electrolyte secondary battery wherein a lithium transition metal composite oxide containing at least Ni and Mn as the transition metals and having a lamellar structure is used as the positive electrode active material is characterized in that the lithium-transition metal composite oxide used as the positive electrode active material further contains zirconium. L'invention concerne une batterie secondaire à électrolyte non aqueux dans laquelle un lithium-oxyde composite de métaux de transition contenant au moins Ni et Mn comme métaux de transition et présentant une structure lamellaire est utilisé comme un matériau actif d'électrode positive, et caractérisée en ce que le lithium-oxyde composite de métaux de transition utilisé comme matériau actif d'électrode positive contient également du zirconium.
