| description | The invention relates to a battery binder, a lithium ion battery negative plate and a lithium ion battery, and belongs to the technical field of lithium ion batteries to solve a technical problem of providing a binder for the battery. The binder comprises a polymer with a hydrophilic unit and a hydrophobic unit; and in the polymer, a medium-low molecular weight polymer accounts for less than 5 wt% of the total polymer, and the molecular weight of the medium-low molecular weight polymer is less than or equal to 100,000. The binder provided by the invention is strong in adhesive force, simple in preparation method and low in cost, and not only can reflect higher adhesive force, but also can increase the proportion of the active material when the binder amount is 1.5-2% by being compared with the amount of 2.5-5% of an existing negative plate binder, so that the energy density of the battery is increased. |
