  • Patent number: 12609301
    Abstract: Disclosed are a negative electrode plate and a battery. A first negative active material layer is disposed at a bottom layer, and includes a first binder resistant to electrolyte swelling, has a better chemical corrosion resistance, and is not easy to age, so as to ensure long-term bonding, and reduce battery cell expansio. The negative electrode plate can maintain good mechanical strength and elongation at immersion of the electrolyte, so as to ensure that it is not separatedr. A second binder in a second negative active material layer away from the negative current collector uses a high swelling material, the high-swelling binder is in good affinity with the electrolyte, and the electrolyte infiltration speed is good, which facilitates lithium ion conduction. Furthermore, the high-swelling binder is bound to the separator well in a hot pressing process, so as to improve an interface bonding effect.

  • Publication number: 20230369599
    Abstract: The present application provides a boric acid derivative modified binder and a lithium-ion battery including the binder. Surfaces of emulsion particles of the binder are rich in boric acid groups (—B(OH)2). When the binder is applied to an electrode piece of the battery, the boric acid groups can be subjected to a dehydration condensation reaction with —OH in sodium carboxymethyl cellulose dispersant, or with —OH in a functional monomer during the drying process of the electrode piece, to form a three-dimensional network, increasing the bonding force and greatly improving the peeling strength of the electrode piece. The binder can also significantly improve the cycle performance of the lithium-ion battery, thereby prolonging the cycle life of the lithium-ion battery.
