Aspect Ratio, Porosity, Contact Resistance, and Electronic Path Continuity in Electrodes
Electrode continuity depends on the processed distribution of additive length scales, accessible pore structure, particle and collector contacts, direction, and cycling state; high powder aspect ratio or low total resistance alone cannot prove a robust electronic path.
Carbon Conductive Networks in Lead-Acid Batteries: Charge Acceptance, PSOC, and Water-Loss Tradeoffs
Method-conditioned guide to acetylene black, conductive carbon black, graphene-family, and CNT-family networks in lead-acid negative plates, covering conductivity, charge acceptance, PSOC, pores, sulfation, gas evolution, water loss, self-discharge, dispersion, and validation.
Compounding Conductive Carbon Black, CNT, Fiber, Graphene, Metal, and Hybrid Fillers
Compounding Conductive Carbon Black, CNT, Fiber, Graphene, Metal, and Hybrid Fillers — a method-conditioned engineering guide for Conductive Plastics & Coatings covering structure-function behavior at the material, interface, and finished-system boundary, process limits, validation, and qualification boundaries.

Controlling Filler Distribution Across Complex Moldings, Edges, Ribs, and Weld Lines
A molded-part control plan for mapping ESD resistance and filler-distribution indicators across gates, flow paths, edges, ribs, thickness transitions, weld lines, and cavities.
Controlling Solids, Viscosity, Yield Stress, and Coating Stability
Control battery slurry rheology as a history-, temperature-, composition-, and method-dependent process window linking low-shear hold stability, equipment-shear flow, recovery, filtration, coating uniformity, drying, and the final electrode—not as one viscosity or yield-stress value.
Diagnosing High Electrode Resistance Despite Adequate Conductive-Additive Loading
Nominal conductive-additive loading can coexist with high resistance when measurement geometry, retained composition, dispersion, drying gradients, calendering, orientation, binder coverage, particle or collector contacts, moisture, or cycling state is wrong; isolate the first failed boundary before adding carbon.
Diagnosing Humidity-Sensitive Resistance and Static-Decay Failures
A controlled humidity-cycle method for separating moisture-assisted surface conduction, network-junction changes, contamination, contacts, and static-decay system effects in ESD materials.
Dispersing CNT, Graphene, Carbon Black, MXene, Metal, and Hybrid EMI Fillers
Define EMI shielding filler dispersion by the network, process, surface, and shielding outcome required for each filler class rather than by minimum agglomerate size or maximum mixing energy.
Drying Migration, Binder Redistribution, and Conductive-Additive Segregation
Evaporation, diffusion, capillary flow, concentration, binder association, particle mobility, skin formation, and substrate interaction can create through-thickness and in-plane carbon or binder gradients; qualify the actual web temperature, mass-loss, air, solvent, and electrode response.

How Calendering Changes Contact, Density, Porosity, and Resistance
Calendering changes particle coordination, real contact area, additive orientation, pore architecture, collector adhesion, residual stress, and thickness recovery; define the process by actual electrode state rather than roll gap or nominal load alone.
How Carbon Black, CNT, Fiber, Graphite, and Hybrid Additives Build Electrode Networks
Carbon black forms short-range particulate contacts, CNTs and fibers bridge longer gaps, graphite platelets add lateral contact area, and hybrids combine length scales; compare them only after slurry, drying, calendering, electrode geometry, inactive loading, and cycling are matched.
