Sodium-Ion Battery
An emerging battery technology using sodium ions instead of lithium. Lower energy density but uses abundant, cheap materials and performs well in cold temperatures.
Why It Matters
Sodium-ion could significantly reduce grid-scale storage costs by 2028-2030, benefiting all ratepayers. Residential products are expected later as the technology matures.
