Polymer design
Build material hypotheses from functional groups, molecular weight, glass transition temperature, and dispersion state.
CASU China Science and Technology Alliance | Advanced Materials
From polymer interfaces to scalable electrode processes.
Focusing on the water-based battery bonding system, the polymer structure, active materials, conductors, slurry dispersion, coating, drying, rolling, peeling and electrochemical evaluation are connected in series to establish a material language that can be used jointly by R&D and manufacturing.

CASU
Establish a scalable materials engineering chain from polymer design to electrode evaluation.
Material structure, particle interface, slurry rheology, coating drying and electrochemical performance are coupled with each other; every judgment goes back to the same batch of materials, pole pieces and process conditions.
Material interface
Observe the adsorption and bonding between the binder and active materials, conductors and current collectors.
Slurry window
Control dispersion, solids, viscosity, thixotropy, stability and equipment shear conditions.
Pole piece processing
Joint coating uniformity, dry migration, roll compaction and flexible peel performance.
Electrochemical evaluation
Trace results such as rate, cycle, impedance, and expansion back to material and process objects.
Pilot testing and supply
Pay attention to equipment scale-up, batch stability, quality indicators and supply coordination.
Between materials, slurries and pole pieces, verifiable technical objects are seen.
Establish a research and development context based on battery material systems, functional material directions and industrial collaboration objects, allowing images to directly serve material identification and project judgment.
From material issues to electrode process and amplification verification.
Submit the electrode system, active materials, slurry status, coating conditions, existing data and failure performance, and the materials and process team will establish the first round of evaluation path.
Clarify the positive and negative electrode materials, conductors and current collectors
Record solid content, viscosity, dispersion and storage stability
Create binder combinations, variables and controls
Complete coating, drying, rolling, peeling and electrical testing
Curing specifications, batch control and scale-up conditions
Bring material systems and real process conditions into the discussion.
Starting from the existing formula, slurry data and pole piece failure, executable collaborative tasks of material screening, process verification and pilot testing are formed.
