E. Lithium Migration at the Anode: Understanding Its Role in Battery Discharge In the fast-evolving world of energy storage, understanding lithium behavior during battery discharge is crucial for improving performance, safety, and longevity—especially in lithium-ion (Li-ion) batteries. One key phenomenon is E. Lithium ion reduction at the anode during discharge, a fundamental process that powers modern electronics, electric vehicles (EVs), and renewable energy systems. ### What Happens During Discharge? During battery discharge, lithium ions (Li⁺) travel from the anode to the cathode through the electrolyte, generating electric current that powers devices. At the anode, a reversible reduction reaction occurs: lithium ions gain electrons and intercalate (embed) within the anode material, typically graphite in conventional Li-ion batteries.
