ITEMS INCLUDED

Laboratory Stacks

Stacks are the core component of the flow battery energy storage system, where the electrolyte undergoes electrochemical reactions to achieve charging and discharging, determining the power level of the system. Flow batteries have the characteristic of decoupling power and capacity because they store the electrolyte outside the reaction stack: the stack determines the power of the battery, while the amount of electrolyte determines the capacity. It is suitable for research institutions and manufacturers to test flow battery materials or systems.

PRODUCT FEATURES

High performance: Featuring a structural design adopted from large commercial battery stacks, with flow channels that have been thoroughly optimized and validated through engineering, the energy efficiency exceeds 80% under a power density of 200mW/cm²；
