Applications
Sodium-ion batteries for UPS and data centres
Sodium-ion can deliver high power and tolerate frequent cycling, making UPS and data-centre backup a credible use—provided reliability and service evidence match the critical load.
What matters
UPS batteries spend long periods ready, then must respond instantly. Calendar ageing, self-discharge, monitoring and fault availability can matter more than headline energy density.
The detail
The collapse of early suppliers is a reminder that bankability matters. A technically strong cell does not guarantee replacement modules throughout a facility’s life.
Practical conclusion
Evaluate availability, redundancy, maintenance windows, fire strategy and supplier finances alongside performance. Pilot before fleet-wide adoption.
