Correction: Quantifying the ion coordination strength in polymer electrolytes

Abstract

Correction for ‘Quantifying the ion coordination strength in polymer electrolytes’ by Rassmus Andersson et al., Phys. Chem. Chem. Phys., 2022, 24, 16343–16352, https://doi.org/10.1039/D2CP01904C.

The authors would like to make changes to Table 1 and Fig. 4c in the published manuscript. The corrections pertain to the data for the Mg(TFSI)₂ systems, where the wrong concentration of TFSI ions was used for the original calculations. The revised versions of Fig. 4c and the relevant part of Table 1 are shown here.

Table 1 Extracted enthalpy, entropy and derived Gibbs free energy at 25 °C for the dissociation of Mg(TFSI)₂ in PEO, PCL and PTMC

Salt	Polymer	ΔH^0/kJ mol^−1	ΔS^0/J mol^−1 K^−1	ΔG^0/kJ mol^−1
Mg(TFSI)2	PEO	−8.8	13.3	−12.7
	PCL	−12.6	−6.5	−10.7
	PTMC	−9.4	1.4	−9.8

Fig. 4 (c) Van’t Hoff plots of the equilibrium constant K as a function of the inverse temperature for the dissociation equilibrium of Mg(TFSI)₂ in PCL, PTMC and PEO. Dashed lines represent the linear fit to the data.

The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
