The authors would like to clarify the following statements from the published paper (changes are indicated in bold type), and to apologise for any misunderstanding which may have arisen:
From the Results and discussion:
“According to Aymard and co-workers,13 the unique electrochemical discharge reaction is the hydride conversion: however also the alloying of Li into magnesium can occur.”
should be replaced by:

From the Introduction:
“In a series of papers Aymard and coworkers focus their attention on MgH2.13,15,16 However its theoretical performances (2048 mA h g–1 at 0.5 V vs. Li+/Li) are far from being reached: in fact Aymard et al. report a first discharge capacity of only 1064 mA h g–1 in the voltage range 1.0–0.1 V vs. Li+/Li.”
should be replaced by:
“In a series of papers Aymard and coworkers focus their attention on MgH2.13,15,16 However its theoretical performances (2048 mA h g–1 at 0.5 V vs. Li+/Li) and stable cyclabilities are far from being reached: in fact Aymard et al. report a first reversible capacity of only 1064 mA h g–1 in the voltage range 1.0–0.1 V vs. Li+/Li (see abstract of ref. 15) unless a very large amount of additives (>66 weight percent) is used in the electrode formulation (see abstract of ref. 16).”
The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
