<P>PROBLEM TO BE SOLVED: To provide a secondary battery which includes a negative electrode having high durability and low reactivity with an electrolyte. <P>SOLUTION: A negative electrode 23 is formed with a lithium titanate 24 having low reactivity with an electrolyte 21 and a graphite 25 having high charge potential than the lithium titanate 24. An electrolyte coating 26 is formed on a surface of the negative electrode 23 by charging at a charging potential of the graphite 25 after charging at a charging potential of the lithium titanium 24, and thereby the electrolyte coating 26 is interposed between the electrolyte 21 and the lithium titanate 24. <P>COPYRIGHT: (C)2013,JPO&INPIT |
