solid state battery vs lithium ion Page 21

Solid‑state batteries promise higher energy density and better safety thanks to solid electrolytes, but they’re expensive and not in mass‑market EVs yet. Lithium‑ion is today’s workhorse—mature, cheaper, and everywhere—though it still fusses about heat and loses capacity over time.

Below are quick pros and cons for each, so you can decide whether to buy now or keep refreshing press releases. Australia-wise, li‑ion powers what you can actually register today.

• Solid‑state pros: Potentially higher energy density; improved safety; faster‑charge potential; better cold performance (lab‑dependent).
• Solid‑state cons: Early‑stage manufacturing; limited supply; high cost; long‑term fast‑charge durability still being proven.

• Lithium‑ion pros: Proven tech; broad chemistries (NMC, LFP); falling $/kWh; established warranties and recycling routes.
• Lithium‑ion cons: Lower peak energy density; thermal runaway risk if abused; capacity fade with high‑SOC fast charging.
