Comment on The Sodium-Ion Battery Revolution Has Started
Creat@discuss.tchncs.de 1 day agoThe thing currently costs at least 50% more than the closest equivalent LiFePo4 from the same brand. The only real advantage seems to be it’s ability to handle sub freezing temperatures, but usability still drops dramatically (both capacity and available power delivery). Everything else is straight up worse in this one in direct comparison.
It’s only the first product, so it’ll most certainly get better. Also as numbers of products sold rise, costs fall. Once these are cheaper, that are a real choice.

CATL wholesale pricing per kWh is already almost 50% below lifepo with a goal of sub $20/kWh pricing in coming years.

Sorry but the theoretical price of cells isn’t relevant to the consumer. The price of products containing them is. This thing costs currently on the official site 900€ (with some sort of sale going on). The Elite 100v2 with comparable capacity, but using LiFePo4 (included in the same current sale) costs just 550€. To add insult to injury, it also outperforms the Na model in nearly every aspect except sub-freezing performance. This includes an abysmal solar charging efficiency of roughly 50% at normal temperature. Somehow.
Again, once the price reflects the cell cost, this could be a very attractive option. At the moment, unless you’re into camping in sun-zero climates, it’s just a very bad deal.

bluetti is grossly overpriced and heavy, and does not even have the features of comparable models from last year. It’s not because there isn’t mass avaialbility of cells/packs they could build from. It’s just overcharging.
