CALB Unveils Zhijiu Series Long-Cycle Energy Storage Cells and Zero-Carbon Ark Platform at ESIE 2026

On April 1, the 14th Energy Storage International Summit and Exhibition (ESIE 2026) opened in Beijing. CALB participated in the event under the positioning of "AI + Energy, Zero-Carbon Solution Provider", and officially launched three next-generation long-cycle energy storage cells of its Zhijiu Series — 392Ah, 588Ah and 661Ah — at a press conference on the exhibition's opening day.

Full Series Long-Cycle Cells: 15,000 Cycles, Zero Attenuation in First Three Years

The newly released Zhijiu Series long-cycle energy storage cells cover three capacity variants of 392Ah, 588Ah and 661Ah, developed based on the company's one-year mass production and delivery experience with the 314Ah Gen2.0 ultra-long cycle energy storage cells. The product's core specifications reach 15,000 cycle lifespans, 25-year calendar life, and zero capacity attenuation in the first three years of operation.

In terms of technical approach, the long cycle life is achieved through systematic optimization of cathode, anode materials and electrolyte, as CALB took the lead in realizing the large-scale application of lithium replenishment technology in the industry. For the cathode, lithium replenishment agent is added to improve initial capacity and cycle stability; for the electrolyte, proprietary additives are used to enhance the stability of the Cathode Electrolyte Interphase (CEI) film, effectively suppress side reactions between cathode materials and electrolyte, significantly resolve gas generation issues common during lithium replenishment, and achieve "lithium replenishment without gas generation"; for the anode, high-strength granulation process and artificial SEI-like interface design are adopted to enhance the anode's structural stability.

This series of cells is mainly targeted at scenarios including new energy consumption, grid fluctuation regulation, AIDC, and zero-carbon parks. It can meet the long-life requirements of energy storage systems under high-frequency dispatch, and support the 25-year life cycle goal of "same lifespan for PV and energy storage".

"Zero-Carbon Ark" Launched: Leveraging Battery Expertise to Enable Urban Smart Energy Upgrade

At the press conference, CALB and Bingwu Digital Intelligence jointly launched the "Zero-Carbon Ark" energy management platform, a zero-carbon software infrastructure product positioned as a smart energy hub for parks and cities.

In terms of technical architecture, Zero-Carbon Ark aggregates data from generation, grid, load and storage links through AI algorithms to realize collaborative optimization and build an urban energy hub. For its implementation path, CALB adopts a progressive "from parks to cities" strategy: taking zero-carbon parks as the smallest unit for single-point demonstration, gradually promoting to regional overall planning, and finally realizing smart dispatch and zero-carbon transformation of zero-carbon smart cities. At present, the full-scenario zero-carbon ecological demonstration project of Zero-Carbon Ark has completed market verification, and will fully enter the mass delivery stage subsequently.

At the exhibition site, CALB also delivered an in-depth sharing on the technical details and application cases of its zero-carbon solutions under the theme of "Zero-Carbon Ark · Smart Future - CALB AI + Energy Empowers New Ecology of Zero-Carbon Parks".
