PNNL

PNNL researchers have discovered that dissolving a simple sugar into the electrolyte in a flow battery boosts peak power output by a remarkable 60%. What's more, after being constantly cycled for a year, the battery lost almost none of its capacity.

Researchers at the Pacific Northwest National Laboratory have developed an unusual way to harvest wave power, with a gently rolling cylinder designed around the triboelectric effect that causes static shocks after you walk on certain carpets.

A team at Pacific Northwest National Laboratory has demonstrated a type of "hibernating" battery that can preserve its energy for months at a time and release it on demand when heated up, ticking some important boxes for renewable energy storage.

There is still some work to do in bringing current redox flow battery designs up to speed in terms of both performance and sustainability, but a new approach tackles the problem on both these fronts, by drawing on a compound commonly found in candles.

The Pacific Northwest National Laboratory (PNNL) in association with LCW Supercritical Technologies has made a potentially important breakthrough for the nuclear industry by extracting five grams of powdered uranium, called yellowcake, from ordinary seawater.

The US Department of Energy's Pacific Northwest National Laboratory (PNNL) has found a way to potentially change the 34 billion gal (128 billion liters) of raw sewage that Americans create every day into 30 million barrels of biocrude oil per year.

Learning from your mistakes is a key life lesson. After unintentionally creating nanorods, researchers realized their accidental invention behaves weirdly with water, demonstrating a 20-year old theory and potentially paving the way to low-energy water harvesting systems and sweat-removing fabrics.

Zinc-manganese batteries are back in the spotlight now that a team of researchers has made them much more reliable, with greater numbers of charging cycles than ever before. And all for around the same price as a standard lead-acid car battery.

Researchers at the Pacific Northwest National Laboratory have developed the strongest​ titanium alloy ever made. They believe the new material could be used in the production of lighter and cheaper vehicle components, and lead to the development of other high strength alloys.

A new flow battery technology promises to drastically lower the cost and sustainability of running energy storage systems. The battery uses low-cost and sustainable organic materials for electrolytes rather than the usual commodity metals, and it could be retrofitted to existing batteries.

Dendrites – thin conductive filaments that form inside lithium batteries – reduce the life of these cells and are often responsible for them catching fire. Now researchers claim to have produced an electrolyte that completely eliminates them while also boosting carrying capacity and efficiency.

A new redox flow battery developed at the Pacific Northwest National Laboratory (PNNL) more than doubles the amount of energy that this type of cell can pack in a given volume, approaching the numbers of lithium-ion batteries.
