摘要：

Young's modulus for Li12Si7 was determined from nanoindentation testing. Young's modulus for Li12Si7 was 52.0 +/- 8.2 GPa. This value is in excellent agreement with estimated values of Young's modulus calculated from predicted values of bulk modulus using density functional theory. Published by Elsevier B.V.
