Title: Sodium-ion batteries set to go mainstream as they hit LFP price and energy density parity
Post by: Redaktion on September 28, 2025, 11:58:38
After the world's largest battery maker managed to craft a sodium-ion battery with high energy density ready for mass production, the future of the technology looks bright. Sodium-ion batteries are slated to proliferate as soon as 2026 now.

Some lithium batteries are over 300 watts per kg now. Not 165.

Those are NMC chemistry Lithium batteries - better capacity, charging speed but costlier, worse in cold weather and with a significantly shorter lifespan (~2000 cycles to 70%).
'Na' batteries are being compared to LFP chemistry Lithium batteries. Those have 205 Wh/kg capacity at the top end. Are better in cold weather. And have ~5000 cycles to 70%. And are the cheapest option on the market RN.
So these 'Na' batteries are a viable option 'in their category' as long as they reach price parity with LFPs.
