New battery system pairs lithium and sodium cells to protect data centers from outages

Highstar unveiled a layered battery portfolio for AI data centers, mixing lithium-ion and sodium-ion cells.

The system is designed for rack-level backup, facility UPS/HVDC support, and grid-scale storage.

It aims to handle power spikes, heat stress, and volatile loads from AI and GPU-heavy workloads.

The approach could improve uptime and thermal stability while easing grid and infrastructure constraints.
