BATTERY BINDER, LITHIUM-ION BATTERY NEGATIVE ELECTRODE PLATE AND LITHIUM-ION BATTERY
Disclosed are a battery binder, a lithium-ion battery negative electrode plate and a lithium-ion battery. The adhesive contains a polymer having both hydrophillic and hydrophobic units. In addition, in the polymer, a medium-to-low molecular weight polymer is less than 5 wt % or less based on total amount of the polymer, and the molecular weight of the medium-to-low molecular weight polymer is less than 10000. The adhesive has a strong adhesive force, and the preparation method therefor is simple and low 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 active material can be increased, thereby increasing the energy density of a battery.

BINDER COMPOSITION FOR SECONDARY BATTERY
A binder composition that can be used in a dry electrode mixture or electrode slurry for producing an electrode is disclosed. The binder composition comprises a water-compatible copolymer, and has a liquid content of less than 85%by weight, based on the total weight of the binder composition. The reduced liquid content of the binder composition improves transport and storage efficiency compared to a conventional wet binder composition. The binder composition disclosed herein is versatile, and can be used successfully in a dry electrode mixture and an electrode slurry. Batteries comprising electrodes prepared with the binder composition disclosed herein have electrochemical performances comparable to batteries comprising electrodes produced via a conventional wet binder composition.
