🧠 What It Means
Common in early hybrid vehicles like the Toyota Prius.
Rechargeable and more environmentally friendly than older battery chemistries.
Can complement hydrogen systems in off-grid storage and hybrid applications.
❗ Key Challenges
Lower energy density than lithium-ion.
Memory effect can reduce performance over time.
Being phased out in many high-demand applications.
🦁 Muzaffar’s Comment
“It might be older tech, but NiMH laid the foundation for hybrid systems—and still has niche roles to play.”
🦉 Sameer’s Comment
“I didn’t realise hydrogen was already in some older battery systems. That’s a cool connection to today’s tech.”
