Achieving high energy densities in lithium-ion batteries requires advancements electrode materials and design. This study investigated the incorporation of multi-walled carbon nanotubes (MWCNTs) with commercial viability as conductive additives into two types high-nickel cathode materials, LiNi0.8Co0.1Mn0.1O2 LiNi0.92Co0.07Mn0.01O2. To ensure a uniform distribution within electrodes, MWCNTs were uniformly dispersed solvent using ultrasonication, most effective straightforward dispersion method. enhancement improved both electronic ionic conductivity, facilitating formation an efficient electron transfer network. Unlike cells only black, electrodes exhibited lower internal resistances, higher diffusion. The capacity retention 89.5% over their cycle life, 2 wt% superior rate capability at current density 1 C. highlights that incorporating well-dispersed effectively enhances electrochemical performance ultrahigh-loading cathodes (LIBs), providing valuable insights
