Sunwoda Power Leads Energy Storage Innovation with 314Ah and 600+Ah Cells at ESIE 2025

Beijing, April 10-12, 2025 – Sunwoda Power, a global leader in energy storage technologies, showcased its full spectrum of energy storage products and solutions at the ESIE 2025 exhibition in Beijing. The event highlighted Sunwoda’s advanced 280Ah, 314Ah, and 600+Ah battery cell series, alongside the groundbreaking launch of its 2MWh liquid-cooled mobile energy storage system.

Next-Gen Energy Storage Cells Redefine Industry Standards

As a centerpiece of the exhibition, Sunwoda unveiled its high-capacity battery cell portfolio, emphasizing breakthroughs in energy density, cycle life, and cost efficiency.

1. 314Ah Cell:

   • Achieves >95% round-trip efficiency (RTE) and 12,000+ cycles, ideal for renewable energy storage and shared grid applications.

   • Enables 5MWh capacity in a 20-foot container, reducing lifecycle energy costs by 20%.

   • Globally certified and already deployed in 400MWh projects in Q1 2024.
     Dr. Tao Chen, General Manager of Sunwoda’s Energy Storage Division, noted: “Our 314Ah cell, mass-produced since late 2023, demonstrates superior energy retention in real-world grid applications, outperforming lab benchmarks.”

2. 600+Ah Cell (625Ah):

   • Delivers 2kWh per cell, enabling 6.8MWh systems in 20-foot containers with 33% higher space efficiency.

   • Features advanced thermal management and gas exhaust systems for enhanced safety.

   • Targets mass production in 2025, with 6.5+MWh systems launching in Q2 2026.
     Dr. Chen emphasized: “This cell will revolutionize high-density markets like China and the Middle East, slashing infrastructure costs by 30%.”

2MWh Mobile Energy Storage System: A Game-Changer

The newly launched mobile system integrates liquid cooling and AI-driven monitoring, designed for rapid deployment in emergency power supply and off-grid scenarios.

Global Strategy: Navigating Market Shifts

With 20% of 2024’s energy storage battery shipments attributed to its 314Ah cells, Sunwoda is expanding globally to address geopolitical challenges:

• Partnering with Siemens on a “Battery Passport” platform for EU carbon compliance.

• Establishing factories in Hungary and Thailand to bypass U.S. tariffs.

• Targeting 25% annual growth in overseas markets through 2026.

Driving the Core of New Energy Systems

“Energy storage is no longer auxiliary—it’s the backbone of sustainable grids,” stated Dr. Chen. Sunwoda’s vertically integrated approach—from cells to full-system integration—positions it as a key enabler of the global energy transition.
