Pacific Northwest National Laboratory (PNNL) is announcing a new zinc-polyiodide redox flow battery that uses an electrolyte that has more than two times the energy density of the next-best flow battery and may exceed lithium-ion. The new zinc-polyiodide redox flow battery is described in the team’s paper published in Nature Communications. The zinc-polyiodide redox energy […]

A Harvard University team of scientists and engineers has demonstrated a new type of battery technology that could fundamentally transform the way electricity is stored for the electric grid.  The new technology could make power production from renewable energy sources such as wind and solar far more economical and reliable. The problem is between the […]

MIT researchers have engineered a new rechargeable flow battery that doesn’t rely on expensive membranes to generate and store electricity.  Instead the battery stores and releases energy in a system that relies on a phenomenon called “laminar flow”.  In a laminar flow two liquids are pumped through a channel, undergoing electrochemical reactions between two electrodes […]

A team of researchers from Drexel University’s College of Engineering has developed a new method for quickly and efficiently storing large amounts of electrical energy.  Their target is supporting efficient use of intermittent renewable energy resources, a goal that hinges on the ability to store the energy when it is produced and dispense it when […]
