文摘
- •
Co increases low-temperature capacities, and cycle life of superlattice alloy.
- •
Co deteriorates high-temperature voltage stand and high-temperature performance.
- •
Alloy with 4.7 at% Co shows good balance among main battery requirements.
- •
Failure of Co-free superlattice alloy was due to the pulverization of the cathode.
- •
Pulverization, oxidation and shortage are failure modes for Co-containing alloys.
