Solid-State Batteries Enter Mass Production: Energy Density Breaks 500Wh/kg
A major battery manufacturer announced that solid-state batteries have entered mass production with an energy density of 500Wh/kg, enabling EVs with over 1,000km range.
Production Details
| Parameter | Value |
|---|---|
| Energy density | 500 Wh/kg |
| Volumetric density | 1,200 Wh/L |
| Cycle life | 1,500 cycles (>80% capacity) |
| Production start | Q3 2027 |
| Capacity | 1 GWh/year |
Technical Advantages
vs. Liquid Lithium Batteries
| Metric | Liquid | Solid-State | Improvement |
|---|---|---|---|
| Energy density | 250 Wh/kg | 500 Wh/kg | 2x |
| Safety | Fire risk | Non-flammable | — |
| Charge speed | 30 min | 15 min | 2x |
| Low-temperature performance | -20°C | -30°C | Better |
Application Impact
Electric Vehicles
- 100kWh battery pack weight: drops from 600kg to 300kg
- Range: increases from 600km to 1,200km
- Charge time: drops from 30 minutes to 15 minutes
Consumer Electronics
- Smartphone battery life: stretches to 3–5 days
- Laptops: all-day battery becomes the baseline
- Drones: flight time improves by 80%
Pricing
| Application | Unit Price | Outlook |
|---|---|---|
| Automotive battery pack | ¥800/kWh | Costs still elevated |
| Consumer electronics | ¥50/Wh | Viable for flagship devices |
