The first energy storage exhibition at home and abroad in 2025 is about to start. What new technologies will be unveiled? This article lists the top ten technological evolution trends of lithium battery energy storage, covering multiple dimensions such as thermal management, system architecture, and material iteration.
Trend 1: String architecture will dominate the design of large storage systems. String energy storage systems rely on the refined control of "one cluster, one management" to accelerate the replacement of traditional centralized architecture and become the mainstream choice in the field of large storage.
Trend 2: Thermal management technology transitions to "intelligent liquid cooling + full-domain temperature control" The thermal management system (TMS) will develop from the traditional air-cooled and liquid-cooled separation design to a highly integrated and intelligent multi-source collaborative direction.
Trend 3: Deep integration of grid-type energy storage and power grid The energy storage converter (PCS) adopts virtual synchronous generator technology to simulate the rotational inertia and damping characteristics of the generator set to smoothly pass through the black barrier blind area of off-grid switching and have fault crossing capabilities.
Trend 4: Semi-solid/solid-state batteries are moving towards the first year of application and may become the upgrade direction of 300Ah+. The breakthroughs of solid-state batteries in energy density (above 400Wh/kg) and safety (no risk of electrolyte leakage) will reshape the energy storage technology route.
Trend 5: Sodium-ion batteries usher in the era of "low-cost energy storage" Sodium batteries have become an ideal choice for many energy storage scenarios due to their rich resources (sodium reserves are 420 times that of lithium) and low-temperature performance advantages (-40℃ capacity retention rate ≥80%).
Trend 6: Large-capacity and long cycle life technology goes deep "Light storage and life" is the common goal pursued by the industry. How can the cycle life of lithium iron phosphate batteries commonly used in the industry break through the "10,000 times threshold"? Conventional chemical systems cannot meet this requirement. Material modification (such as lithium supplementation) and system synergy can change the "cycle life remains in publicity".
Trend 7: Intelligent operation and maintenance drives full life cycle cost reduction AI and IoT technologies deeply empower energy storage operation and maintenance to achieve "predictive maintenance + asset appreciation".
Trend 8: AC/DC integrated design promotes "energy storage installation revolution" The AC/DC integrated energy storage system is an innovative design that integrates DC-side battery units and AC-side PCS (power conversion system). This design not only simplifies the structure of the energy storage system, but also greatly improves the efficiency, performance and safety of the system.
Trend 9: Safety technology shifts from "passive protection" to "active defense"
Multi-level safety protection system becomes the industry standard.
First, the fire protection system is upgraded. The multi-level fire extinguishing solution of Pack-level perfluorohexanone + cabin-level aerosol has a response time of <3 seconds and a re-ignition rate of less than 0.1%.
Second, AI risk warning, through the fusion analysis of voltage, temperature, and gas concentration, predicts the risk of thermal runaway 48 hours in advance.
Trend 10: High integration accelerates the "solar storage parity era"
On the one hand, the energy storage system is deeply coupled with photovoltaic and charging facilities to build an energy self-consistent ecology.
On the other hand, facing the energy storage projects getting closer and closer to downtown, the environmental friendliness of the energy storage system has also become an important direction of high integration.
