LiNova Energy Debuts Metal-Free Battery to Eliminate Data Center Fire Risks
Monrovia-based LiNova Energy has unveiled PolyPower, a polymer-cathode battery cell designed to replace volatile metal-based storage in data centers. By removing nickel and cobalt, the technology eliminates thermal runaway risks while promising a 90% reduction in cathode material costs compared to traditional lithium-ion chemistries.
The surge in global data center power demand, expected to double by 2030, has created an urgent need for backup systems that can handle high-density compute loads without fire hazards. LiNova’s solution relies on proprietary, metal-free precursors that evolve CO2 instead of oxygen during degradation, preventing the explosive thermal runaway common in conventional batteries.
Independent testing at the University of California San Diego confirmed that the cells maintain high-rate performance and capacity retention under stress. Saft North America also verified the technology’s safety profile, noting no thermal runaway during abuse simulations. These cells are currently available in a pouch-format for testing, with cylindrical versions expected in Q3 2026. Integration into hyperscaler-spec battery backup units is scheduled for the fourth quarter of 2026, targeting a market that requires both high power density and supply chain resilience.
