CALB Debuts Groundbreaking Zhijiu Ultra-Long-Cycle Storage Cells & AI-Powered Zero-Carbon Ark Platfo

Against the backdrop of surging global demand for long-duration, high-reliability energy storage solutions to support large-scale renewable energy integration, the 14th Energy Storage International Summit and Exhibition (ESIE 2026) kicked off in Beijing on April 1, 2026. At this flagship industry event, CALB, a leading global lithium-ion battery manufacturer, made a landmark appearance under its brand positioning of "AI + Energy, Zero-Carbon Solution Provider", unveiling two transformative new offerings for the global energy storage market: the Zhijiu series of next-generation ultra-long-cycle energy storage cells, and the AI-driven Zero-Carbon Ark smart energy management platform, via a dedicated opening-day press conference.

Zhijiu Series: Industry-Leading 15,000-Cycle Ultra-Long-Life Energy Storage Cells

The newly launched Zhijiu series comprises three capacity variants: 392Ah, 588Ah, and 661Ah, all built on the proven mass production and global delivery track record of CALB’s 314Ah Gen 2.0 ultra-long-cycle energy storage cells, which have been in full volume production for 12 months. The series sets a new industry benchmark for energy storage cell durability, with core performance specifications including a 15,000-cycle rated lifespan, a 25-year calendar life, and zero measurable capacity attenuation over the first three years of continuous operation.
To deliver this industry-leading cycle life, CALB has implemented systematic material and structural optimizations across the cathode, anode, and electrolyte, while achieving the industry’s first large-scale commercial application of high-efficiency lithium replenishment technology. On the cathode side, a proprietary lithium replenishing agent is integrated to boost initial capacity and long-term cycle stability. For the electrolyte formulation, custom-developed additives are used to enhance the robustness of the Cathode Electrolyte Interphase (CEI) film, effectively suppressing side reactions between the cathode material and electrolyte, while resolving the persistent industry challenge of gas generation during lithium replenishment — achieving CALB’s breakthrough "gas-free lithium replenishment" performance. On the anode side, a high-strength granulation process and artificial SEI-like interface design are deployed to strengthen the anode’s structural stability during repeated high-frequency charge-discharge cycles.
Engineered for utility and commercial energy storage applications, the Zhijiu series is optimized for core use cases including renewable energy curtailment reduction, grid frequency and voltage fluctuation regulation, AI data center (AIDC) backup and peak shaving, and zero-carbon industrial park energy systems. The cells are designed to meet the rigorous durability requirements of energy storage systems under high-frequency grid dispatch scenarios, while enabling the industry’s key 25-year "co-equal lifespan for PV and energy storage" design target for utility-scale renewable projects.

Zero-Carbon Ark Platform: AI-Driven Smart Energy Hub for Park & Urban Zero-Carbon Transition

Alongside the Zhijiu cell series, CALB also used the ESIE 2026 stage to jointly launch the "Zero-Carbon Ark" energy management platform with Bingwu Digital Intelligence, a specialized zero-carbon software infrastructure product positioned as a unified smart energy hub for industrial parks and urban energy systems.
Built on a future-proof technical architecture, the Zero-Carbon Ark platform leverages advanced AI algorithms to aggregate and analyze real-time data across the full energy value chain: power generation, grid transmission, end load, and energy storage. This unified data framework enables end-to-end collaborative optimization of distributed energy assets, creating a fully integrated urban energy hub that maximizes renewable energy utilization, reduces operational energy costs, and enhances grid stability.
For market rollout, CALB has adopted a phased "park-first, city-later" implementation strategy: starting with zero-carbon industrial parks as the smallest modular unit for single-point demonstration and validation, then scaling to regional energy master planning, and ultimately delivering smart dispatch and full zero-carbon transformation for smart cities. The platform’s full-scenario zero-carbon ecological demonstration project has already completed full market validation, and is set to enter the full-scale mass delivery phase in the coming months.
During the exhibition, CALB also delivered an in-depth technical presentation, sharing detailed technical specifications and real-world application case studies of its end-to-end zero-carbon solutions, under the theme of "Zero-Carbon Ark · Smart Future - CALB AI + Energy Empowers the New Zero-Carbon Park Ecosystem".
The dual landmark launches at ESIE 2026 solidify CALB’s position as a full-stack zero-carbon solution provider, bridging advanced battery cell technology with AI-powered energy management software to address the full spectrum of global energy storage and zero-carbon transition needs.
