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

[No abstract available]

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).’
