Year One of Solid-State Battery Mass Production: EVs with 1,000km Range Begin Delivery
CATL and BYD simultaneously launch mass-produced EVs with solid-state batteries, both exceeding 1,000km range and charging to 80% in 15 minutes, marking a new phase in the EV range competition.
Two Giants Launch
On June 11, China's two battery giants—CATL and BYD—simultaneously launched mass-produced EVs equipped with solid-state batteries, officially marking the entry of electric vehicles into the "solid-state era."
CATL — "Kirin Solid-State"
- Partner brands: Avatr, Zhiji, NIO
- Battery capacity: 150 kWh (vehicle total)
- Range: CLTC 1,080 km
- Fast charge: 80% in 15 minutes (400kW ultra-fast charger)
- Price premium: ~¥60,000 more than equivalent liquid battery models
- Delivery: Orders open now; deliveries begin Q3
BYD — "Blade Solid-State"
- Partner brands: Full BYD lineup (Han, Tang, Seal)
- Battery capacity: 140 kWh
- Range: CLTC 1,020 km
- Fast charge: 80% in 18 minutes (350kW ultra-fast charger)
- Price premium: ~¥50,000 more than equivalent liquid battery models
- Delivery: Already in mass production; deliveries begin this month
Solid-State vs. Liquid Lithium-Ion
| Metric | Solid-State | Ternary Lithium | LFP |
|---|---|---|---|
| Energy density | 400-500 Wh/kg | 200-250 Wh/kg | 160-180 Wh/kg |
| Range (150kWh) | 1,000+ km | 700-800 km | 600-700 km |
| Safety | Extremely high (non-flammable) | Moderate (thermal runaway risk) | Relatively high |
| Low-temp performance | Excellent | Moderate | Poor |
| Cycle life | 3,000+ | 1,500 | 3,000+ |
| Cost | High (initial) | Moderate | Low |
Market Reaction
Following the announcements, CATL's stock rose 6.3% in a single day; BYD gained 4.8%. Multiple securities firms raised price targets for both.
Consumer pre-order enthusiasm exceeded expectations:
- NIO ET9 (Kirin Solid-State version): Over 20,000 pre-orders in 72 hours
- BYD Han Solid-State version: 15,000 pre-orders on day one
Infrastructure Challenges
Large-scale adoption of solid-state batteries still faces these challenges:
- Insufficient ultra-fast chargers: Fewer than 5,000 400kW ultra-fast chargers nationwide
- High cost: 5-6万 yuan premium over liquid battery models limits adoption
- Recycling system: Solid-state battery recycling technology is still immature
Industry Significance
Academician Chen Jun, battery expert at the Chinese Academy of Sciences, stated:
"Solid-state batteries are the ultimate form of lithium-ion batteries. China's first-to-mass-production means we've secured the right to define the next generation of batteries. This is of strategic significance for the entire new energy industry."
