New long-duration, extended capacity Na-Al battery design for grid storage

Green Car Congress

Researchers led by the Department of Energy’s Pacific Northwest National Laboratory (PNNL) have extended the capacity and duration of sodium-aluminum batteries. The new sodium-based molten salt battery uses two distinct reactions. h is achieved with an estimated raw active materials cost of $7.02 of peak charge capacity.

Stanford team develops sodium-ion battery with performance equivalent to Li-ion, but at much lower cost

Green Car Congress

Stanford researchers have developed a sodium-ion battery (SIB) that can store the same amount of energy as a state-of-the-art lithium ion, at substantially lower cost. Thus, further research is required to find better sodium host materials. The sodium salt makes up the cathode; the anode is made up of phosphorous.

UT Austin team devises new strategy for safe, low-cost, all-solid-state rechargeable Na or Li batteries suited for EVs

Green Car Congress

John Goodenough, known around the world for his pioneering work that led to the invention of the rechargeable lithium-ion battery, have devised a new strategy for a safe, low-cost, all-solid-state rechargeable sodium or lithium battery cell that has the required energy density and cycle life for a battery that powers an all-electric road vehicle.

New high energy, highly stable cathode for sodium-ion batteries

Green Car Congress

F 0.7 , for sodium-ion (Na-ion) batteries (NIBs). Large-scale energy storage systems are needed to deal with intermittent electricity production of solar and wind. Recently, attention has been refocused on room-temperature Na-ion batteries (NIBs) as a low-cost alternative technology as compared to LIBs. Click to enlarge.

New nanoparticle copper compound cathode could enable low-cost, long-life and high-power potassium-ion batteries for grid storage

Green Car Congress

Short-term transients, including those related to wind and solar sources, present challenges to the electrical grid. Stationary energy storage systems that can operate for many cycles, at high power, with high round-trip energy efficiency, and at low cost are required. Cost is a greater concern. —Yi Cui.
