JAC, in a partnership with Volkswagen, has been shipping a vehicle called the Sehol or E10X with sodium-ion ... [continued]
The 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.
More durable, cheaper, can be operated at a wider temperature range and much safer, but at a cost of lower energy density.
They look like a big step forward for uses where density matters little, like grid energy storage or small scale home backups.
