Title (EN) CATHODE ACTIVE MATERIAL AND METHOD OF MANUFACTURING SAME, AND NONAQUEOUS ELECTROLYTE SECONDARY BATTERY
(FR) MATÉRIAU ACTIF DE CATHODE ET SON PROCÉDÉ DE FABRICATION, ET BATTERIE SECONDAIRE À ÉLECTROLYTE NON AQUEUX
(JA) 正極活物質及びその製造方法、並びに非水電解質二次電池
Abstract: front page image
(EN) In a nonaqueous electrolyte secondary battery provided as a cathode with a cathode active material comprising a layered lithium composite oxide, when charging or discharging has been carried out under prescribed conditions, the cathode active material satisfies the relationship 0
(FR) Dans une batterie secondaire à électrolyte non aqueux équipée d'une cathode comprenant un matériau actif de cathode contenant un oxyde composite de lithium en couches, lorsqu'une charge ou une décharge a été exécutée selon des conditions prescrites, le matériau actif de cathode satisfait la relation 0
(JA) 層状リチウム複合酸化物からなる正極活物質を正極として備えた非水電解質二次電池で、所定条件で充放電を行った際に、該正極活物質は、5サイクル目の放電での電圧Vと電池容量Qを電圧Vで微分した値dQ/dVとのグラフにおいて、3.9Vを超えて4.4V以下のピークトップのdQ/dV絶対値|Ia|、3.5Vを超えて3.9V以下のピークトップのdQ/dV絶対値|Ib|及び2.0V以上3.5V以下のピークトップのdQ/dV絶対値|Ic|から求めたピーク強度比r=|Ic|/(|Ia|+|Ib|+|Ic|)が0<r≦0.25を満たすものである。
