Disclosed are a battery adhesive, a lithium-ion battery negative electrode plate and a lithium-ion battery. The adhesive contains a polymer having both hydrophilic and hydrophobic units. In addition, in the polymer, a medium-to-low molecular weight polymer is 5 wt% or less based on the total amount of the polymer, and the molecular weight of the medium-to-low molecular weight polymer is ≤ 100,000. The adhesive has a strong adhesive force, and the preparation method therefor is simple and low in cost. Compared with an exiting negative electrode plate adhesive amount of 2.5-5%, an adhesive amount of 1.5-2% can not only show a higher bonding force, but also the proportion of an active material can be increased, thereby increasing the energy density of a battery. |
