| titleOfInvention | Negative active material for secondary battery and secondary battery using the same |
| abstract | Disclosed is a negative active material, which has a small change in a volume during charge/discharge, so that electric insulation is not incurred well, has excellent initial efficiency and an excellent capacity maintenance characteristic. Further, a fine crystalline region exists on a matrix of an alloy, and lithium may be more easily dispersed according to the existence of the fine crystalline region. An object of the present invention is to provide a negative active material, in which a ratio of the fine crystalline region is represented by an amorphization degree, and which is optimized in designing a battery through a measurement of an expansion rate after 50 cycles. The present invention provides a negative active material for a secondary battery, which is an alloy formed by a chemical formula below, and in which a ratio of Ti to Fe in the negative active material for the secondary battery has 1:1 and a ratio of Si : Ti or Si : Fe in the negative active material for the secondary battery has a range of 5:1 to 9:1. Si- - n x Ti y Fe z Al u (x, y, z, and u are at%, x: 1-(y+z+u), y: 0.09 to 0.14, z: 0.09 to 0.14, and u: larger than 0.01 and less than 0.2). |
