Anhui Anwa New Energy Launches World's First GWh-Level Solid-State Battery Production Line with Internationally Leading Technical Indicators

On July 4, 2025, Anhui Anwa New Energy Technology Co., Ltd. announced the successful rollout of the first batch of engineering prototypes from its independently developed GWh-level new-type solid-state battery production line, the world's first of its kind. After the final set of key equipment arrived in November 2024, the company spent over six months debugging and overcoming production process and equipment challenges, achieving full-line integration. This milestone marks a new phase in China's solid-state battery manufacturing technology.

**Company Background and Technical Collaboration**
Founded in June 2020 with equity participation from Chery Group, Anwa New Energy is a high-tech enterprise prioritized for cultivation by Anhui province, Wuhu city, and the Economic Development Zone. Collaborating with international partners such as the US-based 24M, the company integrates global R&D resources to focus on solid-state battery innovation and industrialisation. Its products achieve internationally leading levels in safety, energy density, and cost control.

**Core Technologies and Performance Parameters of the Production Line**
1. **Equipment Integration**: The line integrates eight major functional modules, including electrode coating, separator lamination, and dynamic heat sealing, with a total length exceeding 35 meters and a designed annual capacity of 1.25GWh.
2. **Precision Manufacturing**:
- High-pressure coating technology adapts to slurries with varying solid content, achieving micron-level precision.
- At a production speed of 20m/min, "roll-to-roll" processes and dynamic tolerance alignment technology maintain electrode-separator alignment accuracy within 0.5mm.
- High-power laser cutting eliminates dust pollution, while 40 smart cameras and X-Ray detection systems enable full-process quality monitoring.
3. **Process Innovation**:
- Streamlines traditional lithium battery production from 11 steps to 5, applying dry electrode technology to reduce fixed asset investment by 30% and energy consumption by 20%.
- The line is compatible with multiple battery systems, including NCM, LFP, and sodium-ion.

**Product Performance and Plans**
The first 1.0 prototypes passed China's new GB38031-2025 standard and nail penetration tests without electrolyte leakage, achieving "non-flammable and non-explosive" performance. Energy density metrics:
- First-generation products exceed 300Wh/kg.
- Second-generation prototypes targeting 400Wh/kg are under trial production.
- Plans to launch 500Wh/kg all-solid-state batteries by 2027.

**Industrial Layout and Outlook**
Anwa New Energy's 150-acre solid-state battery industrial park in Wuhu has completed 12 core buildings. The production line’s launch lays the foundation for batch supply in 2024, with applications in NEVs, ESS, and the low-altitude economy, driving global new energy technology advancement.

The successful launch of Anwa New Energy’s GWh-level solid-state battery line represents not only a technological breakthrough for the company but also a significant milestone in China’s new energy sector’s transition to next-generation battery technology. This achievement will profoundly impact industry competition, technological evolution, and market applications.

1. **Technological Breakthrough: Accelerating Solid-State Battery Industrialisation**
Anwa’s key innovation lies in its "dry electrode + multi-system compatibility" process, reducing traditional lithium battery steps from 11 to 5 while achieving 300Wh/kg energy density (targeting 400Wh/kg for the second generation). Stable mass production could significantly lower costs (30% reduction in fixed asset investment, 20% lower energy consumption), overcoming the high-cost, low-yield barriers plaguing solid-state battery industrialisation.

**Global Comparisons**:
- Toyota plans mass production of all-solid-state batteries from 2027 to 2030 but remains in pilot stages.
- QuantumScape (US) has yet to achieve GWh-level capacity.
- Domestic players like Qingtao Energy and WELION New Energy are active, but Anwa leads in scale (1.25GWh) and process integration.

Anwa’s rapid progress highlights Chinese companies’ engineering prowess, potentially reshaping global solid-state battery competition.

2. **Market Impact: A New Variable in Power Batteries and ESS**
Anwa’s "non-flammable and non-explosive" batteries (validated by nail penetration tests) address safety concerns of liquid lithium batteries, particularly for:
- High-end EVs: 300Wh/kg energy density outperforms mainstream LFP (~180Wh/kg), enhancing range and reducing pack size.
- ESS power stations: High safety mitigates fire risks, aligning with grid-level storage needs.
- Low-altitude economy (e.g., eVTOL): Lightweight and high energy density are critical.

Successful 2024 batch supply may pressure CATL, BYD, and others to accelerate solid-state battery development, sparking a new tech race.

3. **Challenges and Risks: Production Stability and Cost Control**
Despite breakthroughs, industry-wide hurdles remain:
- Interface resistance: Solid electrolyte-electrode contact may affect fast charging.
- Supply chain maturity: Key materials (e.g., sulfide/oxide electrolytes) lack scaled supply.
- Cost competitiveness: Even with 30% lower equipment costs, initial prices may exceed liquid batteries, requiring policy support or premium markets.

4. **Policy and Industrial Synergy**
Anwa’s progress aligns with China’s strategic need for autonomous new energy tech. Chery’s equity stake provides OEM application scenarios (e.g., high-end EV models). Anhui’s new energy cluster (Gotion High-tech, CALB, etc.) may foster upstream-downstream collaboration, accelerating ecosystem development.

**Conclusion: A New Starting Point for China’s Solid-State Battery Industry**
Anwa’s GWh-level line marks solid-state batteries’ transition from labs to mass production, but commercial success hinges on long-term reliability and cost optimization. If its approach gains market traction, China could lead next-gen battery tech, challenging Japan and South Korea’s dominance. Over the next 2–3 years, industry attention should focus on Anwa’s production data and customer feedback, which may set the global solid-state battery development trajectory.

With the world’s first GWh-level line operational, Anwa’s 150-acre industrial park in Wuhu has completed 12 core buildings. This breakthrough not only prepares the company for 2024 mass production but also offers innovative solutions for EVs, ESS power stations, and the low-altitude economy, propelling global new energy technology forward.
