▎ 摘  要

NOVELTY - Pre-dispersion solution comprises an anode additive containing lithium-based compound (I), a first conductive material and a binder. The first conductive material includes natural graphite, artificial graphite, carbon black, carbon nanotubes, graphene, acetylene black, carbon black, ketjen black and/or carbon fibers. USE - The pre-dispersion solution is useful for lithium secondary battery anode. ADVANTAGE - The pre-dispersion solution improves dispersibility and workability of additives; suppresses side reactions that may occur during preparation of cathode slurry while; minimizes loss of cathode additive included in cathode slurry; and improves electrical properties of electrode manufactured. DETAILED DESCRIPTION - Pre-dispersion solution comprises an anode additive containing lithium-based compound of formula (LipCo(1-q)M1qO4) (I), a first conductive material and a binder. The first conductive material includes natural graphite, artificial graphite, carbon black, carbon nanotubes, graphene, acetylene black, carbon black, ketjen black and/or carbon fibers. M1=W, Cu, Fe, V, Cr, Ti, Zr, Zn, Al, In, Ta, Y, La, Sr, Ga, Sc, Gd, Sm, Ca, Ce, Nb, Mg, B, and/or Mo; p=5-7; and q=0-0.5. INDEPENDENT CLAIMS are also included for: manufacturing pre-dispersion solution; and cathode slurry for lithium secondary batteries.
