Conductive PowdersFrom lab to production: conductive powder expertise you can trust
Driving Energy Innovation
Anode & Cathode Expertise
We understand that high-performance batteries demand precision at every layer – starting at the electrode level. Our engineering solutions address the unique challenges of each electrode, enabling manufacturers to achieve superior conductivity, uniformity, and mechanical integrity in dry electrode manufacturing.
Whether you’re working with established materials or exploring new chemistries, our expertise ensures seamless integration into scalable production.
Anode
Graphite, silicon-graphite blends, and hybrid powders – each tailored for optimal dry electrode integration, supporting higher energy density and cycle life. We help you balance conductivity with mechanical stability for robust anode layers.
Cathode
LFP (lithium iron phosphate), NMC (lithium nickel manganese cobalt oxide), and high-nickel cathode materials – our solutions promote uniformity and high conductivity even in thick, high-loading electrodes, driving improved power output and manufacturing efficiency.
Validate and optimize with confidence
Conductive Powders Expertise
At our facility, we offer hands-on conductive powder testing tailored for dry electrode development.
The process begins with powder samples provided by the customer. These powders are processed on-site through calendering to form a self-supporting film. From this film, we punch out samples for in-house analysis. All measurements are conducted using state-of-the-art instruments directly on-site, allowing for fast turnaround.
In close collaboration with the customer, we evaluate and optimize these results to support improved dry coating performance and material efficiency. This enables informed decisions early in the development process – helping to reduce scaling risks and increase consistency in downstream manufacturing.

Whether you’re pioneering the next generation of energy-dense cells or refining existing formulations for better efficiency and cost performance, Matthews Engineering is your partner at every stage. Our end-to-end solutions integrate precision machinery, deep process knowledge, and continuous support – so you can move seamlessly from prototype to full production with confidence.
We don’t just supply equipment; we help you build a scalable, future-ready manufacturing ecosystem.
Laboratory Calender
Fine-tune electrode compression and density with our precision Laboratory Calender. This step allows you to replicate production-level calendering forces and evaluate mechanical strength, adhesion, and uniformity before scaling.
Pilot production
Our pilot lines allow you to validate your electrode formulations and processes in a controlled, industrially relevant environment. This step ensures that your materials and methods translate efficiently from lab-scale concepts to scalable manufacturing without unexpected challenges or costly delays.
Machinery deployment
When you’re ready to scale, we supply precision-engineered machinery—including lab mixers, pilot coaters, production calenders, and slitting units—that’s designed for dry electrode processes. Our equipment integrates intelligent automation and IIoT features, ensuring consistent quality, high throughput, and long-term operational flexibility.
Continuous support
Our commitment doesn’t end at installation. We provide comprehensive operator training, process optimization consulting, and aftermarket services including spare parts, upgrades, and troubleshooting. This ensures your production lines operate reliably and evolve with your needs as your business grows.
