Current Chemistries

The chemistries in production EVs on Australian roads today.

LFP — Lithium Iron Phosphate

Budget & volume EVs ~150–170 Wh/kg (cell)

Uses lithium iron phosphate cathode; no cobalt or nickel.

Pros

Excellent cycle life (3,000–5,000 cycles)
Highly thermally stable — very low fire risk
Lower cost, no cobalt/nickel sourcing concerns
Can safely charge to 100% regularly

Cons

Lower energy density → heavier pack for same range
Reduced range in cold weather
Lower cell voltage

NMC — Nickel Manganese Cobalt

Mainstream long-range EVs ~200–250 Wh/kg (cell)

Balanced cathode blending nickel (energy), manganese (stability) and cobalt (longevity).

Pros

Higher energy density → longer range, lighter pack
Better cold-weather performance than LFP
Mature, high-volume manufacturing

Cons

Shorter cycle life (~1,000–2,000 cycles)
Less thermally stable than LFP
Uses cobalt and nickel (cost & ethical sourcing)
Best kept between 20–80% for longevity

NCA — Nickel Cobalt Aluminium

Performance / premium EVs ~250–270 Wh/kg (cell)

Aluminium boosts stability of a high-nickel cathode; used by some Tesla long-range cells.

Pros

Highest energy density of current production cells
Strong range and performance

Cons

Lower cycle life than LFP
Higher cost and cobalt content
More sensitive to heat than LFP

Emerging / Near-Future

Entering production now or within the next few years.

LMFP — Lithium Manganese Iron Phosphate

LFP successor ~180–210 Wh/kg (cell)

Adds manganese to LFP to raise voltage and energy density while keeping the phosphate structure.

Pros

LFP-level safety and cycle life
~15–25% more energy density than LFP
Better cold-weather performance than LFP
No cobalt or nickel

Cons

Still below NMC energy density
Lower electrical conductivity (needs optimisation)
Earlier in commercial scale-up

Sodium-ion (Na-ion)

Low-cost city EVs ~120–160 Wh/kg (cell)

Uses abundant sodium instead of lithium; the first production cells are now appearing.

Pros

Cheap, globally abundant raw materials
Excellent cold-weather performance
Can be discharged to 0V and shipped safely
Fast charging

Cons

Lower energy density → heavier packs
Shorter cycle life than mature LFP (improving)
Manufacturing ecosystem still scaling

Energy density figures are indicative cell-level ranges and vary by manufacturer, pack design and form factor (prismatic, pouch or cylindrical). Commercial availability of emerging and future chemistries is evolving rapidly. This guide is for general education only — always confirm current specifications with the manufacturer.
