Introduction

CALB, a pioneer in energy storage solutions, made a significant impact at Intersolar Europe 2026 by showcasing its next-generation ZHIJIU Energy Storage Solutions. This new portfolio emphasizes advanced battery cells, liquid-cooled storage systems, and integrated life-cycle services designed to propel the ongoing energy transition in Europe.

Innovative Energy Solutions

The ZHIJIU Energy Storage Solutions are built on CALB's long-cycle battery technology and standardized system platform. These innovations cater to a wide range of applications, extending from large-scale energy storage installations to commercial and industrial projects. By offering cells, systems, and after-sales services in a single package, CALB is dedicated to helping its clients reduce the Levelized Cost of Storage (LCOS) while enhancing safety, efficiency, and long-term project returns.

Key Features

Among CALB's standout innovations were their high-capacity battery technologies suited for utility-scale projects, including:

• - 661 Ah Stacked Cell: Leveraging CALB's third-generation stacked technology coupled with advanced lithium refill technology, this cell promises up to 15,000 charge cycles without power degradation in the initial three years and a calendar life of up to 25 years.
• - Liquid-Cooled Energy Storage Containers: CALB introduced its second-generation liquid-cooled energy storage container with a capacity of 6.25 MWh. This model boasts a 25% increase in energy capacity compared to its predecessor while reducing the number of system components by around 40%.

Moreover, CALB's modular liquid cooling systems can manage outputs of 6.9 MWh in a 20-foot container and over 10 MWh, maximizing energy density, simplifying transport and installation, and accelerating project execution.

Commercial and Industrial Applications

For commercial and industrial use, CALB launched liquid-cooled cabinets with outputs of 261 kWh and 418 kWh. These products incorporate advanced ventilation, explosion pressure relief, and active fire protection systems, offering flexible deployment options and comprehensive international certifications. Their economic viability throughout the life cycle is reinforced by a combination of durable battery cells and widespread liquid cooling technology.

Commitment to Innovation

In addition to system solutions, CALB offers long-life battery cells, including the world-renowned 314 Ah cell from generation 2.0, forming a solid foundation for new energy storage applications. As a leading innovator in battery technology, CALB accelerates the evolution of energy storage through cutting-edge cell technology, a standardized system architecture, and diverse application possibilities to support Europe's transition to a cleaner and more sustainable energy future.
