Dual Breakthroughs in Battery Technology: Peking University Achieves 350Wh/kg Anode-Free Lithium Metal Battery; Sunwoda Mass Produces 10,000mAh Phone Battery
Release time:
2026-05-30
【Core Summary】
The battery technology sector has recently witnessed two significant breakthroughs:
-
Peking University team led by Professor Zou Ruqiang, in collaboration with Zhejiang Jinyu New Energy, has achieved a key breakthrough in high-energy-density anode-free lithium metal batteries, reaching 350 Wh/kg in a 30Ah pouch cell with 84.4% capacity retention after 180 cycles.
-
Sunwoda officially announced on May 29 that it has begun mass production of a 10,000mAh phone battery, setting a new capacity record for consumer electronics batteries.
These two breakthroughs represent the latest progress in next-generation frontier technology and consumer-grade mass production technology, respectively.

Technical Approach:
The research team proposed a synergistic strategy combining in-situ anode lithium compensation and near-surface fluorination reconstruction of the cathode. This approach effectively addresses the critical challenge of short cycle life in anode-free lithium metal batteries by optimizing electrode interface stability, significantly improving cycling stability.
Industry Significance:
Anode-free lithium metal batteries are considered a major direction for next-generation high-energy-density batteries. The 350 Wh/kg energy density far exceeds current mainstream lithium-ion batteries (typically 200-300 Wh/kg) and approaches or even surpasses some laboratory-level solid-state batteries. This breakthrough opens new possibilities for battery technology iteration in long-range electric vehicles, electric aviation, and related fields.
2. Sunwoda: 10,000mAh Phone Battery Enters Mass Production
Announcement Date: May 29, 2026 (disclosed on investor interaction platform)
Product Highlights:

|---|
Industry Significance:
Current mainstream smartphone batteries typically range from 4,000 to 6,000mAh. The mass production of a 10,000mAh battery represents a significant leap in consumer electronics endurance. This product is particularly well-suited for:
-
Heavy-use scenarios (outdoor work, long-distance travel)
-
Rugged phones and outdoor-specific devices
-
Gaming phones with extreme battery life requirements
Industry Observation:
Behind the mass production of high-capacity phone batteries lies the combined advancement of improved energy density, optimized packaging processes, and mature safety technologies. Sunwoda's breakthrough signals that consumer electronics batteries are moving from "sufficient" to "abundant."
3. Trend Summary
These two breakthroughs point to a common trend: battery technology is moving from "meeting demand" to "creating demand."
