The invention relates to a negative pole material for a lithium-ion secondary battery, and the negative pole material comprises composite particles in core-shell structures, conductive additives and an amide type high-temperature-resistant binder, wherein each composite particle in the core-shell structure comprises an inner core and an outer shell layer, each inner core contains at least one of elemental silicon, a silicon oxide and a silicon alloy, and each outer shell layer is coated by one or more of inorganic materials, namely C, Cu, Ni, Fe, Cr, Al2O3, TiO2, LiPO3, Li2Si2O5, Li2SiO3, Li4SiO4, Li8SiO6 and SiO2; and the amide type high-temperature-resistant binder is one or more of polyamide, imide and amide-imide. The invention further relates to a negative pole containing the negative pole material and a preparation method thereof. The invention further relates to a battery containing the negative pole. The battery has the advantages of higher charge-discharge capacity, better cycle property and high safety, and is suitable for various mobile electronic devices or devices requiring mobile energy sources for driving.
