  "textContent": "Provided is a negative-electrode active material, which is capable of constituting a lithium ion secondary cell exhibiting excellent cell characteristics. [0002] The negative-electrode active material for a lithium ion secondary cell of the invention includes a mixed material of silicon oxide particles composed of silicon oxide and rod-shaped iron oxide particles composed of iron oxide. It is preferable to use iron oxide particles having a plurality of pores in a surface, and an electrode reaction is effectively carried out.",
