HiTHIUM Unveils 587Ah ∞Cell Battery: A New Standard in Energy Storage

April 10, 2025 — At the 13th Energy Storage International Summit and Exhibition (ESIE 2025), HiTHIUM unveiled its revolutionary ∞Cell 587Ah energy storage battery (dimensions: 73.5×286×216mm, W×L×H) and the ∞Power 6.25MWh 2h energy storage system, marking a potential industry milestone for high-capacity battery standardization. The 587Ah lifepo4 battery entered global sampling in April 2025, with the ∞Power 6.25MWh system slated for mass production in the second half of the year.

Notably, HiTHIUM collaborated with five industry leaders to jointly showcase the battery at the event—the first time multiple manufacturers have aligned on a unified size for 587Ah-class products. This unprecedented collaboration signals HiTHIUM’s rapid transition from product launch to large-scale application, leveraging technological innovation and industrial synergy to position the ∞Cell 587Ah as the benchmark for next-gen high-capacity energy storage.

Technical Breakthroughs: Optimizing Size for 587Ah Batteries

As China’s energy storage sector shifts toward large-scale, high-efficiency solutions, the demand for standardized battery dimensions has intensified. With 500Ah+ batteries and 6MWh+ systems dominating market trends, the industry faces a critical challenge: maximizing capacity, safety, and cost-efficiency within the confines of standard 20-foot shipping containers.

HiTHIUM addressed this by tackling five critical technical boundaries:

1. 20-foot container spatial limits

2. 50-ton maritime weight restrictions

3. 1500V voltage thresholds

4. System architecture optimization

5. LFP chemistry performance balancing

Through AI-driven modeling and multi-objective algorithms, HiTHIUM identified 587Ah as the optimal capacity for balancing system integration efficiency and cost. The resulting 73.5×286×216mm design—paired with a 415Wh/L energy density—achieves a 6.5% volumetric improvement over 314Ah batteries while delivering competitive $/kWh performance, extended lifecycle (10,000+ cycles), and compliance with GB/T and UL safety standards.

∞Power 6.25MWh 2h System: Elevating Large-Scale Storage
Built on HiTHIUM’s ∞Pack+ multi-scenario platform, the ∞Power 6.25MWh system integrates seamlessly into standard 20-foot containers, offering:

• 90% shorter maintenance time via patented external active balancing and triple-valve liquid cooling technologies.

• SIL2-rated safety through ultra-low thermal conductivity barriers and dual-functional BMS.

• 15% reduced footprint compared to 5MWh systems.

• Industry-leading TCO via pre-integrated architecture, slashing R&D costs for integrators.

Industry Leadership in Action

By co-defining the 587Ah battery standard with partners, HiTHIUM reinforces its role as a technological pioneer and ecosystem driver. The launch aligns with its mission to deliver extreme cost efficiency, uncompromised safety, user-centric maintenance, cross-scenario adaptability, and sustainable innovation—propelling the global energy transition into a new era of intelligence and scalability.
