From a OneD battery science patent: They use SiH4 and temperatures of 300 to 900C. Coretec uses CHS SI6H12 as a starter ( liquid )silicon source not a gas silicon like SiH4 which Coretec have already stated CHS is better. And our emperature range is far lower.

Of one advantage, among others, the system and manufacturing method of the present application achieves utilization or conversion of the Si source material (e.g. Silane) to Si nanowires approaching 100%. In some embodiments, utilization of the Si source material is in the range of about 30-100%, or in the range of 30-99.5%, and more usually in the range of about 70-99.5%. In one exemplary embodiment, Si nanowires are grown in the system described herein using the following conditions: temperature of about 300-900° C., silane concentration of about 5-100% in the process gas mixture of: SiH4 of about 5-100 wt. %, He (or Ar or N2) of about 0-50 wt. %, and H2 of about 0-50 wt. %, at a growth time in the range of about 10-500 minutes. The aforementioned conditions and tumbler rotation are preferably controlled by computer with automatic software for the production.
