Development of carbon conductive additives for advanced lithium ion batteries

Rheological properties and stability of NMP based cathode slurries for lithium ion batteries

“…Both types represent homopolymers with different molecular weights (KYNAR 761: 370.000-450.000 g/mol, KYNAR HSV 900: 900.000-1.300.000 g/mol). As a conductive additive, carbon black (Super C65, Timcal Ltd., Switzerland) with a BET surface of 62 m 2 /g and a mean TEM particle size of 35 nm was used [17].…”

Electrode thickness control: Precondition for quite different functions of graphene conductive additives in LiFePO4 electrode

“…Very recently, great efforts have been made to improve the volumetric energy density by developing high-performance electrode materials with high volumetric capacity and decreasing the additives content in the electrode [6][7][8]. Conductive additive is a key component in batteries because many electrode materials, such as LiMn 2 O 4 , LiFePO 4 (LFP) and Li 4 Ti 5 O 12 , usually have low electrical conductivity [9][10][11][12][13][14]. Graphene (GN), a two-dimensional carbon nanosheet, has been widely used in energy storage systems, and because of its high electrical conductivity, it has great potential to be used as a novel conductive additive [15][16][17][18].…”

Optical and electrical characterization of carbon nanoparticles produced in laminar premixed flames

“…Particularly, the electrical conductivity of carbon blacks is a key parameter for their use in electrical components and devices [8,9], and as conductive additives for polymer composites [10,11]. Many scientific reports can be found in literature on this subject, and on the role of the electron tunneling mechanism [12] and the influence of composition, graphitization, particle size, density and surface chemistry on electrical transport properties in commercially available carbon blacks [13][14][15].…”
