Effect of S-doped carbon nanotubes as a positive conductive agent in lithium-ion batteries

“…Due to the requirements for stability and resistance to acid and alkaline corrosion, conductive additives in lithium-ion batteries are mostly carbon-based materials [8][9][10][11] , including conductive carbon black, conductive graphite, carbon bers, graphene, and carbon nanotubes. In addition to their excellent electrical conductivity, carbon nanotubes have a ber-like structure that provides good exibility and mechanical stability [12][13][14] , It is conducive to improving the processability of the battery plate and the cycle life of the battery.…”

“…Most active materials used in cathode materials for lithium-ion batteries have poor conductivity, resulting in relatively large electrode internal resistance and low utilization of active material, which seriously affects the performance of the battery in terms of rate capability, cycling stability, and safety [2,3] , the contraction and expansion of materials in the process of charging and discharging also greatly affect the safety and life of the battery [4,5] . Conductive additives can increase the conductive contact between active materials, improve the electronic conductivity, generate micro-current between active materials and collector surfaces, reduce electrode contact resistance, accelerate electron mobility [5][6][7] .Therefore, it is often necessary to add additional conductive materials to improve battery performance.Due to the requirements for stability and resistance to acid and alkaline corrosion, conductive additives in lithium-ion batteries are mostly carbon-based materials [8][9][10][11] , including conductive carbon black, conductive graphite, carbon bers, graphene, and carbon nanotubes.

Enhancing the electrochemical properties of TiNb2O7 anodes with SP-CNT binary conductive agents for both liquid and solid state lithium ion batteries

“…Cheon et al 38 used SP and Lonza-KS6 as the binary conductive agents, the results showed that the batteries containing binary conductive agents have better cycle life than those using single conductive agents. Cao et al 39 employed SP-CNT binary conductive agent and effectively improved the electrochemical performance of NCM cathode. The SP-CNT binary conductive agent exhibited a larger specific surface area and build an efficient composite conductive network, which is an effective way to prepare high-performance electrodes.…”

Multi-Objective Optimization of Kinetic Characteristics for the LBPRM-EHSPCS System

“…Long-term studies on battery electrodes have mostly examined the effects of active materials [9,10], formulations [11][12][13], and conductive agent selection [14][15][16] on battery electrochemical performance. Precision and efficiency for the pole plate rolling process are increasingly urgently needed as battery performance and safety requirements improve.…”
