Before Sodium-ion batteries, Lithium-ion batteries have changed the way we charge our devices. Scientists have been working on producing even more powerful versions due to the problem of dendrites (spiky lithium structures that grow on the anode while charging) that can represent a severe safety hazard by short-circuiting the battery.
Scientists and engineers have been working on Sodium-ion batteries for about a decade in an attempt to eliminate the dendrite problem by replacing both the lithium and cobalt used in conventional lithium-ion batteries with cheaper, more environmentally friendly sodium, and a recent breakthrough suggests they may have found the solution.
A team of University of Texas researchers, with support from the National Science Foundation, has produced a stable sodium-based battery material.
This novel technology avoids dendrite formation and can recharge as quickly as a regular lithium-ion battery, but it has the potential to provide better energy output than lithium-ion batteries.
How these Sodium-ion batteries works
Rolling a thin sheet of sodium metal onto an antimony telluride powder, then folding the sheet again to generate a fresh anode material, is the basic mechanism behind this innovative battery technique.
This results in a homogeneous distribution of sodium atoms that resists dendrite development and corrosion, making the solution safer and more stable.
Regardless of global uncertainties, demand for stationary energy storage is increasing at an exponential rate across a wide range of applications. A stationary energy storage system, in most circumstances, entails the use of batteries as well as other components. Scientists believe that this technology could give a steady, sustainable, and less expensive answer to meet the ever-increasing need.
