Investigation of the volume expansion of LixSnAu compounds. (a) Cycling performances of different LixSnAu electrodes (including pre-cycling treatment in shading area) at 3 C up to 2000, 4000 and 6000 cycles. Very good stability is obtained after ∼500 cycles of charge-discharge. (b) Comparison of the volume expansion of LixSnAu with LixSn based on DFT calculations. (c) Representative structures of Li2SnAu, Li3SnAu and Li4SnAu associated with volume change.
