Nickel-Metal Hydride (NiMH) and Lithium-Ion (Li-Ion)
Nickel-Metal Hydride (NiMH) vs. Lithium-Ion (Li-Ion) Batteries in Toyota Cars
| Feature | Nickel-Metal Hydride (NiMH) | Lithium-Ion (Li-Ion) |
|---|---|---|
| Primary Use | Older Toyota hybrids (e.g., Prius, Camry Hybrid) | Newer Toyota hybrids and plug-in hybrids (e.g., RAV4) |
| Energy Density | Lower (40-60 Wh/kg) | Higher (100-265 Wh/kg) |
| Weight | Heavier due to lower energy density | Lighter, higher energy per kg |
| Charge/Discharge Rate | Moderate, suited for steady hybrid use | Faster, ideal for EVs and high-performance hybrids |
| Thermal Management | Air-cooled (simple, reliable) | Air-cooled or liquid-cooled (better thermal control) |
| Cost | Generally cheaper to manufacture | More expensive due to advanced materials |
| Lifespan | 8-15 years (good thermal stability) | 8-12 years (dependent on usage and cooling) |
| Safety | Stable, less prone to thermal runaway | Requires sophisticated BMS for safety |
| Environmental Impact | Less efficient recycling but less toxic | More recyclable but contains more hazardous materials |
| Charging Efficiency | Lower, with more energy loss during charge | Higher efficiency, faster charging |
| Application | Preferred in budget hybrids (Yaris Hybrid) | Used in performance and plug-in hybrids (RAV4 Prime) |
Why Toyota Uses Both:
- NiMH: Used in budget-friendly hybrids for cost-effectiveness and long life.
- Li-Ion: Used in premium hybrids and plug-in hybrids for superior performance, lighter weight, and faster charging.
