Hithium launches new 5MWh liquid‑cooled energy storage systemHithium has officially released its new 5MWh liquid‑cooled energy storage system, designed to deliver higher energy density, improved safety, and lower lifecycle costs for large‑scale storage applications. The company states that the new system increases energy density by 46 percent compared to its previous generation.

The 5MWh unit uses Hithium's latest 314Ah LFP cells, which feature a redesigned internal structure and upgraded thermal‑management materials. The system supports precise liquid cooling, enabling more stable operation under high‑load and high‑temperature conditions. According to Hithium, the new design improves thermal uniformity by 30 percent and extends overall service life.

The cabinet integrates a high‑efficiency fire‑suppression system, multi‑level electrical protection, and a new safety‑isolation architecture. These upgrades aim to reduce the risk of thermal runaway and enhance reliability in long‑duration storage scenarios such as renewable‑energy smoothing, peak‑shaving, and grid‑frequency regulation.

Hithium also optimized installation and maintenance. The new system supports modular deployment, front‑access servicing, and rapid replacement of key components. The company claims that installation time has been reduced by 25 percent, while maintenance efficiency has increased by 20 percent.

The 5MWh system is designed for compatibility with mainstream PCS (power conversion systems) and EMS (energy‑management systems), making it suitable for utility‑scale solar‑plus‑storage, industrial parks, and microgrid applications. Hithium says the product will help operators reduce total cost of ownership while improving long‑term operational stability.
