World Premiere! Countdown to delivery of VNTech’s 400Wh/kg sulfide-based all-solid-state battery 2025
🔥 All-Solid State Battery Mass Production Milestone: 60Ah Sulfide Battery to be Delivered Within the Year
Official Confirmation from VNTech:
✅ 400-500Wh/kg ultra-high energy density (crushing liquid batteries by 150%)
✅ 60Ah cells will be delivered in small quantities to strategic customers in December 2025
✅ Dual technology routes in parallel: sulfide system + oxide/polymer composite system
Procurement value: the technology enables eVTOL vehicles to increase range by 40% and humanoid robots to double their working hours!
⚡ Semi-solid technology foundation building: full lead in commercialization process
📊 Three generations of product matrix to accurately cover needs
| product generation | energy density | Cycle life | Areas of application | mass production node |
|---|---|---|---|---|
| first generation | – | – | Passenger cars (2022 loading) | mass produce |
| second generation | 330Wh/kg | 4000 laps | Low-altitude economy/humanoid robots | 2025 |
| third generation | 400Wh/kg | keep sth. confidential | Flying cars/high-end equipment | 2026 |
Customer evidence: has won the Guangzhou Automobile / Dongfeng / Sany Heavy Industry / Xiaopeng Huitian (flying car) and other orders
🌐 Sulfide route breakthrough: why international buyers must lock VONER?
💎 1. Unique Advantage of Flexible Manufacturing for Soft Pack Batteries (Keyword: SPS Production Line Technology)
► Same production line compatible with semi-solid → full solid transition production
► Sulfide electrolyte mass production yield increased to 85%+ (industry average <70%)
🛩️ 2. Low Altitude Economy Exclusive Battery Solution
► eVTOL measured data:
2C Continuous Discharge Temperature Rise <15℃ (Conventional Battery >35℃)
Capacity retention rate of 92% at -20℃ (verified by U.S. customers)
⚙️ 3. Subversive Breakthrough in Safety Performance
► All-solid-state batteries completely eliminate the risk of thermal runaway (↑400% safety factor compared to liquid batteries)
► Passed UN38.3 air transportation certification (samples have been shipped by air to customers in Europe and the United States)
📈 Procurement strategy: three steps to seize the scarce capacity
Technical validation: Apply for 60Ah sample test kit (with pinning/overcharging/low temperature report)
Scenario matching: Get the eVTOL Battery Energy Density-Cost Model (Vonergy’s exclusive tool)
Capacity lock: only 37% of delivery quota left for 2025 (as of June 2025)
⚠️ Industry Alert: CITIC CIC’s analysis points out that – –Sulfide all-solid-state batteries will trigger three major changes:
🔸 Flying car manufacturing cost down 30%
🔸 Humanoid robots range bottleneck cracked
🔸 Undeployed companies face technology generation gap within 2 years
