- •
Effects of Si on high-temperature performance of AB5-type alloy are firstly studied.
- •
High-Si alloy shows better thermodynamic stability for high-temperature delivery.
- •
Si profitably affects the high-temperature dischargeability, recoverability and cycling stability.
- •
Si-containing alloys show excellent high-rate dischargeability and peak power at 60 °C.
- •
Si promotes anti-corrosion ability and surface catalytic ability at higher temperature.
