<P>PROBLEM TO BE SOLVED: To provide a non-aqueous electrolyte secondary cell which outputs high power with high current rate. <P>SOLUTION: The non-aqueous electrolyte secondary cell includes: a positive electrode including a positive electrode active material which contains Ni, Mn and Fe and has a lithium composite metal oxide of which BET specific area is no less than 2 m<SP>2</SP>/g and no more than 30 m<SP>2</SP>/g; and a negative electrode including a negative electrode active material made of amorphous carbon material. The lithium composite metal oxide is represented by following formula (A), the formula (A): Li(Ni<SB>1-x-y</SB>Mn<SB>x</SB>Fe<SB>y</SB>)O<SB>2</SB>, where x is a value more than 0 and less than 1, y is a value more than 0 an less than 1, and x+y is a value more than 0 and less than 1. <P>COPYRIGHT: (C)2010,JPO&INPIT |
