| titleOfInvention | Negative electrode active material for lithium ion secondary battery, lithium ion secondary battery using the negative electrode active material, and method for producing negative electrode active material for lithium ion secondary battery |
| abstract | The present invention relates to a composite powder used as a negative electrode active material in forming a lithium ion secondary battery, which has a very small volume expansion / contraction during charge / discharge, high capacity, and excellent long cycle life. Provided are a negative electrode active material capable of producing an ion secondary battery and a lithium ion secondary battery using the negative electrode active material. The negative electrode active material of the present invention is composed of composite particles having a two-layer structure in which tin is arranged at the center and the periphery thereof is coated with nickel, and the ratio of nickel to the total amount of tin and nickel is 5 to 5. It is characterized by 40 atomic%. Moreover, the manufacturing method mixes the aqueous solution containing a tin ion and nickel ion, and the reducing agent aqueous solution containing a bivalent chromium ion, carries out the reduction reaction of tin ion and nickel ion in a liquid mixture, and tin does It is characterized by obtaining composite particles having a two-layer structure which is arranged in the center and whose periphery is coated with nickel.
