I am very pleased to publish an updated figure of merit for fast charging batteries, thanks to the new data points for Na-ion and LFP batteries recently contributed by Li et al. and Liao et al.

Now we have a complete suite of chemistries including NMC, LFP, Na-ion and LTO that are all capable of charging in 10-minute or less to 80% SOC. I see the following:
1. Balanced between energy density and cost, LFP battery stands out as the best choice for automotive applications. I see 90% of auto market shares taken up by LFP in years to come.
2. Na-ion battery must demonstrate 25% lower cost per kWh than LFP before it is commercially viable. This means $37/kWh for Na-ion cells as the current price of LFP is ~$50/kWh for prismatic cells. Thus, the meaningful direction for Na-ion battery development is cost-down or simplifications to get rid of any expensive materials such as oxide cathodes, hard carbon anodes, etc.
