A high ratio of the testing temperature to the melting temperature: a necessary but not sufficient condition for an alloy anode to exhibit low capacity fade

A CaLi2 alloy with micron-sized particles exhibited low specific capacity and rapid capacity fade. These results can be correlated with its low fracture toughness (K-IC approximate to 1 MPa m(1/2)). A high ratio of the testing temperature to the melting temperature (>0.4) is a necessary but not sufficient condition for an anode material to exhibit low capacity fade. The microstructure must also be considered. Published by Elsevier Science B.V.
