Dincă Lab demonstates high-performance Sodium-ion cathode for new battery technology
For decades, scientists have sought ways to counter our dependence on lithium-ion batteries. These traditional, rechargeable batteries energize today’s most ubiquitous consumer electronics – from laptops to cell phones to electric cars. But raw lithium is expensive and is often sourced through fragile geopolitical networks.
This month, the Dincă Group announces an exciting alternative that relies on an organic, high-energy cathode material to make sodium-ion batteries, advancing the likelihood that this technology will find commercialization with safe, cheaper, more sustainable components.
While scientists have made some progress with sodium-ion batteries, hurdles arise largely because of their low energy density: they have shorter battery-run times relative to their size. High power density, which relates to output, also factors into their performance. Achieving high energy density and high power density simultaneously has been an ongoing challenge for alternative batteries.
But the cathode material put forward by the Dincă Group, a layered organic solid called bis-tetraaminobenzoquinone (TAQ), outperforms traditional lithium-ion cathodes in both energy and power densities in a technology that is truly scalable.
Their research has potential for large-scale energy storage applications like data centers, power grids, and commercial-scale renewable energy systems, in addition to electric vehicles.
