Which is why the new sodium-ion batteries are likely to be preferred in cold climates, because even if they cannot reach energy/mass ratios as good as the best lithium-ion batteries, they lose much less of their capacity and charging speed, down to -40 Celsius degrees (-40 Fahrenheit degrees).

While for now sodium-ion batteries have similar prices with lithium-ion batteries, due to being on the market for less than a year, their second advantage is that once their production becomes more mature they should be significantly cheaper than Li-ion batteries.
