Cathode active material (CAM)

The metal-oxide compounds in a battery cathode — NMC, LFP, LCO and others — that dominate battery cost, performance and critical-minerals exposure.

Definition

The electrochemically active compounds coated onto a battery's cathode, determining its energy density, power, lifespan and cost. Principal families include lithium cobalt oxide (LCO), lithium iron phosphate (LFP), lithium manganese oxide (LMO) and nickel manganese cobalt oxides (NMC, in varying ratios); nickel-rich NMC and NCA dominate long-range EVs while cobalt-free LFP gains share.

Overview

What it means

CAM is the single most expensive battery component — roughly 35–45% of cell cost — and the locus of the battery supply chain's sustainability problems: cobalt mining in the DRC (artisanal-mining child-labour exposure), nickel's deforestation and tailings footprint in Indonesia, and concentrated refining capacity. The LFP shift reduces nickel/cobalt exposure but trades energy density and remains China-centric.

CAM composition drives EU Battery Regulation requirements — recycled-content mandates (from 2031), carbon-footprint declarations and due-diligence obligations all key off cathode chemistry — and battery-passport data.

How it is used

Cell makers lock CAM offtakes years ahead; recyclers target CAM metals recovery (hydrometallurgy, direct recycling); ESG due diligence traces cobalt/nickel provenance; procurement tracks CAM price indices as battery-cost drivers.

Why it matters

Decarbonisation's mineral footprint is largely a cathode story — CAM choices determine whether electrification trades fossil dependence for new extraction harms.

How people contribute

Reviewers choose the definition or an overview paragraph, leave a comment or replacement, and attach evidence or a source link.

How comments are used

Editors compare reviewer cards side by side. AI may help find agreement, conflicts, unsupported claims and possible source issues.

What gets published

Only an editor-accepted synthesis changes the public page. Reviewer identities are shown only with consent and verification.

Review board

Comment on a specific line. Each reviewer stays separate until an editor accepts a merged draft.

1Separate reviewer cards

Each person comments on the definition or overview in their own draft card, with role, evidence and suggested wording kept together.

2AI comparison

AI can compare comments against the current text, flag conflicting claims, surface missing evidence and identify where reviewers agree.

3Editor synthesis

An editor merges compatible suggestions into a draft change, checks sources, records disagreements and decides what can be published.
