The second phase of a vanadium redox flow battery trial is to begin following the satisfactory results of phase one tests of a vanadium electrolyte developed by Pacific Northwest National Laboratory and Golden Share Resources Corporation, the company that licensed the material, according to an early June announcement.

The trial looked at the compatibility of the electrolyte, licensed by the Canadian minerals firm, and China’s Hunan Vanadium Valley New Energy Technology battery in a bid to develop a custom-built VRFB.

The initial trial was conducted under the letter of intent over a two-month period that began this March. The second phase will happen over the summer.

The next phase will test the technology’s operational ability under a wider temperature range — particularly higher temperatures which should prove higher reliability — as the companies look to boost overall battery performance.

The first phase involved more than a hundred full cycles of the technology, following the letter of intent in February.

Golden Share, a junior natural resource company focusing on mineral exploration in the province of Ontario, Canada, announced on April 17 it intended to make its energy storage business a new public entity, with the company retaining its mineral exploration business.
