▎ 摘  要

NOVELTY - Low-temperature resistant lithium-ion battery cathode slurry comprises 42-48.5 wt.% cathode material, 0.1-3 wt.% polyacrylate adhesive, 1-2 wt.% conductive agent, 0.6-1.5 wt.% sodium carboxymethyl cellulose, and 45-55 wt.% deionized water. USE - The low-temperature resistant lithium-ion battery cathode slurry is useful in field of lithium-ion battery. ADVANTAGE - The slurry improves compatibility of the electrolyte and the cathode material at low temperature and ion transfer rate, reduces internal resistance, and ensures low-temperature discharge performance of the lithium-ion battery. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: a method for preparing low-temperature resistant lithium-ion battery cathode slurry; and a low temperature resistant lithium-ion battery.
