Anode Materials for Battery Research

A baseline you can trust, and an upgrade to test against it

MCMB is the reference anode for method development and inter-lab comparison. Silicon-carbon adds capacity without the swelling of pure silicon. Every lot ships with its own Certificate of Analysis.

Typical values, not guaranteed limits. Each lot's CoA has the measured values.

Use them together

Start with MCMB as your baseline, then blend Si-C at 5–20% into graphite and measure the capacity gain against a reference that behaves the same every time.

Silicon electrodes breathe

Si-C expands more than graphite as it cycles. Our coin cell wave springs and spacers hold stack pressure so contact doesn't drift during testing.
