Abstract

Triethylboron is a useful precursor for depositing films in an atomic layer deposition process. This precursor is useful for depositing boron containing films. Boron containing films are excellent lubricating coatings for zinc powders, improving their flow properties and simplifying powder handling. This makes the coated zinc powders especially useful for battery applications in which a zinc powder is used as an anode material.

Claims (4)

1. A zinc anode battery comprising zinc particles dispersed in an alkaline electrolyte, a cathode and a separator interposed between the zinc particles and the cathode, wherein the zinc particles have a surface boron nitride coating of up to 10 nm in thickness.

2. The zinc anode battery of claim 1 wherein the boron nitride coating is up to 2 nm in thickness.

3. The zinc anode battery of claim 1 wherein the cathode includes manganese dioxide.

4. The zinc anode battery of claim 1 wherein the cathode is air.
