ERRATUM- Magnesium hydride as a high capacity negative electrode for lithium ion batteries

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: ‘‘According to Aymard and co-workers,13 the electrochemical discharge reaction is the hydride conversion reaction: after that also the alloying of Li into magnesium can occur.’’ 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).’[No abstract available
