The authors regret the incorrect interpretation of ref. 212 in the original article, and the subsequent errors in Fig. 24. The correct discussion of ref. 212 and Fig. 24 is as below.

Fig. 24 (a) Fitted powder XRD patterns of nominal compositions Li₂MnSi_1−xV_xO₄ (0 ≤ x ≤ 0.3) including Li₂MnSiO₄Pmn2₁, Li₂SiO₃, and MnO Bragger reflections. (b) First galvanostatic cycle at C/16 and room temperature of Li₂MnSi_1−xV_xO₄ (0 ≤ x ≤ 0.3). (c) Li₂MnSi_0.75V_0.25O₄ cycled at different rates.

Wagner et al.²¹² synthesized Li₂MnSi_0.75V_0.25O₄/C nanocomposites with the main phases of Pmn2₁ space group and vanadium substituted the Si site via the sol–gel method. It was found that the primary particles were in the size range of 25–40 nm and the particles were surrounded by a thin layer of amorphous carbon, which was intended to increase the electronic conductivity of the materials. Fig. 24a shows that there was no evidence of V rich spinel phases and the MnO peak shapes were broadening at higher V concentrations with the normal compositions Li₂MnSi_1−xV_xO₄ (0 ≤ x ≤ 0.3). This nanocomposite cathode delivered a higher initial discharge capacity of about 160 mA h g⁻¹ at C/16 than that of Li₂MnSiO₄ (Fig. 24b). It also exhibited a better rate capability, as shown in Fig. 24c.

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