Effect of binary conductive agents in LiCoO2 cathode on performances of lithium ion polymer battery

Development of carbon conductive additives for advanced lithium ion batteries

“…We compare the characteristics of these carbon conductive additives, the effectiveness as conductivity enhancer in the electrode as well as processing aspects relating to reference conductive carbons. In addition, we study the specific role as well as possible positive interactions of graphite and carbon black in conductive masses containing both carbon types, as recently reported by Cheon et al for a binary conductive carbon system [23]. Performance and processing differences identified between the different carbon types should give instructions for the optimal application of these new carbons and should suggest potential new solutions for the electrode design and engineering targeting the fine-tuning of the performance of lithium ion cells in the different battery application segments.…”

Functions of polymers in composite electrodes of lithium ion batteries

“…In addition to the electrode capacity, the homogeneity of the C distribution within the composite also affects the cycle life of the electrodes [28][29][30][31]. According to these authors, when the conducting additives are not uniformly dispersed, the AM grains are not evenly utilized and they also experience an unequal topological potential.…”

Substrate-induced coagulation (SIC) of nano-disperse carbon black in non-aqueous media: a method of manufacturing highly conductive cathode materials for Li-ion batteries by self-assembly

“…Conventional fabrication of carbon black modified electrodes entails the mechanical mixing of carbon black and the active material [11][12][13]. NCT (see above) was also used to coat cathodes for Li-ion batteries by adsorbing a thin film of gelatin on the active battery material that acts like a glue and induces a deposition of carbon black on the surface [14].…”
