“…For this experimental setup, L/A was calculated to be 317 m −1 . The measured electrolyte conductivities are displayed in Figure 2 and increase with temperature as expected [32] . The conductivity at 80 • C is approximately three times that at 10 • C (Table S1) linked to increasing Na + /ClO 4 − dissociation and decreasing electrolyte viscosity [33].…”

In recent years, sodium-ion batteries (SIBs) have attracted much attention as an alternative to lithium-ion batteries. Hard carbon (HC) is a well-studied anode material for SIBs; however, the performance as a function of temperature is less established. To investigate temperature dependence of the performance of HC, sodium half-cells with a common NaClO4-based electrolyte were tested at temperatures from 10 to 80 °C. Capacity after 20 cycles at 100 mA g−1 current varied from 90 mA h g−1 at 10 °C to 270 mA h g−1 at 60 °C. Increased temperature significantly improves the HC rate capability, with 120 mA h g−1 capacity found at 60 °C with 500 mA g−1 current. Stability was high at moderate temperature with 220 mA h g−1 capacity remaining after 200 cycles at 40 °C with a current of 100 mA g−1.

“…A recent theory based on Bjerrum´s electrostatic model was developed by Côté and co-workers [10,11] dealing with ion-ion and ion-solvent interactions and through it strong and stable associations in dilute solutions in aprotic solvents are interpreted. Strong ionic associations in similar systems are reported by Reichstädter and co-workers [12] for lithium and sodium perchlorates in 2-butanone being the results deeply discussed in thermodynamic terms.…”

A few non-aqueous dipolar aprotic solvents of medium to high permittivities, low viscosities and large temperature intervals between freezing and boiling points have been used to prepare electrolyte solutions applicable to primary and rechargeable high energy batteries. Lithium perchlorate is a salt often chosen to obtain those systems. In this work low temperature effects on conductivities and association constants of LiClO 4 and Et 4 NBr in six different solvents have been analyzed, using the tetraethylammonium bromide salt for comparative reasons. The temperature interval was −30 ºC to 10 ºC. A few thermodynamic functions resulting from K A , T variations were determined being the results discussed on this basis. The accuracy and precision of results are high; whenever possible they are compared with others previously published.
