A redesign of sodium-nickel chloride batteries could pave the way for new energy advancements. A study published by the Department of Energy’s Northwest National Laboratory found that replacing the standard cylindrical battery shape with a flat disc design allows for delivery of 30% more power at lower temperatures.
These sodium-beta batteries could bring about effective energy solutions to a variety of projects, including electricity substations.
Because a sodium-nickel beta battery is cheaper to manufacture than a lithium-ion battery, consumers may find themselves interested in the comparable performance. Sodium-beta batteries are also safer than their lithium-ion counterparts.
Researchers remodeled the cylindrical design and fashioned a planar battery, similar to a Frisbee or plate. Because the ions can flow in a large area with a short pathway, it creates an environment with lowered resistance.
The flat battery can also be stacked, making it a convenient and compact option for large-scale energy storage.
Researchers will continue to work on the battery redesign to improve lifespan and power capacity, moving toward reducing costs associated with energy storage.
