Sodium vs Lithium: BAIC’s 170Wh/kg Breakthrough Explained

BAIC has just revealed a sodium-ion battery with an energy density of around 170 Wh/kg — and that’s starting to get uncomfortably close to lithium-based batteries like LFP.

For a long time, sodium was seen as the cheaper, lower-performance alternative. But now we’re seeing real progress. Higher energy density, better cold-weather performance, and potentially much lower cost.

So what does this actually mean in the real world?

In this video, we look at how BAIC’s new sodium battery compares to lithium batteries like LFP, where it still falls short, and where it could genuinely start replacing lithium in certain types of vehicles.

We’ll also look at:
– Cost differences between sodium and lithium
– Energy density comparisons (170 Wh/kg vs typical LFP ranges)
– Cold weather performance advantages
– Where sodium batteries actually make sense (and where they don’t)

This isn’t hype — but it is worth paying attention to.

Could sodium-ion batteries start taking market share from lithium? Or is this just another incremental step?

Let me know what you think.
