I think the first generation Sodium-Ion batteries will be better suited to stationary storage - but from memory CATL predicts second generation cells to reach a similar density to their current LFP packs - surely this will make them more suited to cars? Either way it’s good to see a new cell chemistry coming to the market, even if it isn’t used much in cars, it’ll free up lithium supply.
I feel like LFP batteries are/will continue to improve as well. So we might see sodium at the low end of the market like the mini-evs and micro-cars but I think LFP will be the main material used in the mass market EVs we will see in the west.
Agreed, I actually think LFP might become the dominant chemistry in most EVs, not just mid market cars. The energy density and charging speed improvements for LFP batteries coming to market in the next 2-3 years look very promising, especially combined with the perceived increased safety and life span of LFP. I’ll be interesting to see if ‘AB’ mixed chemistry packs become common, i.e a mix of Sodium-Ion and Ternary or LFP cells in the one pack 🤔
Why not paired with lithium ion in cars? They have extreme power density so they can provide the large power needs for acceleration and deceleration and switch over to lithium ion for the energy density for cruising speed.
Generally SIBs actually don’t win on discharge, it’s only in cold weather where that becomes a win for them. However, there are still plenty of benefits in pairing LIBs/SIBs together — see CATL’s so-called ‘AB’ packs.
I still think they will be used in stationary storage more than EVs but they are very good as stationary storage applications
Agreed. This will completely take over stationary storage quite quickly. That frees up lithium for automotive use.
Especially with the modular systems for home & commercial use that are already on the market.

The article mentions that BYD’s partner for this plant is Huaihai Group, a manufacturer of motorcycles, kick scooters, and tuktuks. So this will be used almost exclusively for those verticals.
I don’t know. Ford made a bad ass sodium car in the 90s
