Presently, commercialization of sodium‐ion batteries (SIBs) is still hindered by the relatively poor energy‐storage performance. In addition, low‐temperature (low‐T) Na storage is another principal concern for the wide application of SIBs. Unfortunately, the Na‐transfer kinetics is extremely sluggish at low‐T, as a result, there are few reports on low‐T SIBs. …

Battery storage with current energy capacity investment costs of 100–200 €/kWh would be too costly for these long periods. Simulations show that for renewable systems to be competitive with dispatchable low-carbon technologies, ULDES would need to cost at most around 10 €/kWh. 2 (Note that all costs are given in 2020 euros, while all fuel …
