Negative electrode for non-aqueous electrolyte rechargeable batteries |
摘要 |
The purpose of the present invention is to provide a negative electrode for non-aqueous electrolyte rechargeable batteries of which the capacity is high and of which the decrease of the discharging capacity through the cycles is low by improving the electron conductivity of the surfaces of the active material particle for the negative electrode. In order to achieve this purpose, an active material in the form of a composite particle comprising a phase that can store a lithium ion and includes at least Sn and a phase that cannot store a lithium ion and an electronically conductive material coating part of or the entire surfaces of the above described particle, is used for the negative electrode in the present invention. <IMAGE> |
