The 17th Shenzhen International Battery Technology Exchange Conference/Exhibition (CIBF 2025) brings together the strongest forces of the entire lithium battery industry chain. Energy storage is the most promising branch in various battery technology application scenarios. Many companies in the industry chain showcase their cutting-edge achievements here, highlighting five new trends and highlights in the industry.
1. Energy storage system material innovation: multiple routes in parallelThe performance upgrade of energy storage systems begins with material innovation. In this exhibition, the technical routes of home energy storage solutions and commercial battery energy storage systems present diversified characteristics:
Solid-state batteries: Ganfeng Lithium Battery, Guoxuan High-tech and other companies have launched solid-state energy storage products with energy density exceeding 400Wh/kg, which are highly safe and suitable for industrial and commercial energy storage scenarios. BYD's nano-silicon-based negative electrode and Defang Nano's sulfide electrolyte technology further promote the cycle life of energy storage systems to exceed 10,000 times.
Sodium-ion batteries: CATL Xiaoyao dual-core sodium battery and Yadi Huayu sodium battery products seize the household energy storage market with low cost and high cold resistance (-20℃ discharge rate 92%), providing new options for household energy storage.
Biomass-based materials: Jinshi Technology uses agricultural waste such as coconut shells to develop activated carbon materials, reduce the carbon footprint of supercapacitors, and provide green solutions for small energy storage systems (such as household backup power supplies).
2. Energy storage system integration: digitalization and safety are equally importantThe integrated technology of energy storage systems is accelerating its evolution towards high efficiency and intelligence:
Hybrid energy storage system: Jinshi Technology's 1.25MW/5MWh coupled energy storage system, through the combination of "supercapacitor + lithium battery", intelligently distributes frequency modulation output, with a cycle life of one million times, and is suitable for grid-level commercial battery energy storage systems.
Modular design: BYD Chess Plus energy storage system adopts cluster-level safety protection and self-developed blade batteries to achieve millisecond-level fault response for industrial and commercial energy storage systems (such as integrated photovoltaic storage and charging projects), and improves safety performance by 3 times.
Testing technology upgrade: Ruineng's MW-level energy storage container testing system supports full-chain efficient verification and provides standardized solutions for mass production of energy storage systems.
3. Energy storage system performance: high density and long life become the mainstreamEnergy density and cycle life of energy storage systems continue to break through:
Large-capacity battery cells: Ganfeng Lithium Battery's 587Ah energy storage battery cells (volume energy density 438Wh/L) are suitable for 6.25MWh container systems, with a cycle life of over 12,000 times; Xinwangda's 625Ah battery cells achieve "single battery cell 2 kWh", promoting cost reduction and efficiency improvement of industrial and commercial energy storage systems.
Ships and special energy storage: BYD's NM series ship battery modules provide stable power for ocean-going ships, and Penghui Energy's "Qingtian 520" industrial and commercial energy storage products have an energy efficiency improvement of 4%, demonstrating the reliability of energy storage systems in heavy-load scenarios.
4. Energy storage system safety: the rise of active protection technology
The safety performance of energy storage systems has shifted from passive defense to active intervention:
Liquid nitrogen firefighting solution: Jinshi Technology's coupled energy storage system uses liquid nitrogen technology that can extinguish fires in 5 seconds and cool down to -150°C in 1 minute, minimizing the risk of thermal runaway, especially suitable for household energy storage scenarios.
AI early warning system: BYD Chess Plus energy storage system integrates BMS AFE chip to achieve 1.5mV voltage accuracy monitoring, combined with AI algorithm to predict faults, to ensure the long-term stable operation of commercial battery energy storage systems.
5. Energy storage system applications: Diversified scenarios accelerate implementation
The application scenarios of energy storage systems extend from the grid level to end users:
Industrial and commercial scenarios: BYD Chess Plus supports cluster operation of 8 devices, adapting to the integrated photovoltaic storage and charging project in industrial parks; Penghui Energy's industrial and commercial energy storage product delivery efficiency has increased by 50%, covering the needs of small and medium-sized users.
Special and household scenarios: FS307 forklift batteries meet high-intensity operations, Sky series drone battery life is increased by 35%, and Jinshi Technology supercapacitors provide short-term high-power support for grid frequency modulation, expanding the boundaries of energy storage systems in industrial and commercial and household scenarios.
CIBF 2025 showcases the three core driving forces of energy storage systems: material innovation lays the foundation for performance, system integration optimizes energy efficiency and safety, and scenario innovation broadens market boundaries. From household backup power in home energy storage solutions to grid-level frequency regulation in commercial battery energy storage systems, the energy storage industry is accelerating the transformation of energy structure through technology iteration and scenario adaptation.
