Team creates anode-free Na batteries with high energy densities and long cycle lifetimes

Posted by in categories: energy, sustainability

In recent years, engineers worldwide have been trying to devise new battery and energy storage technologies that are more sustainable and cost-effective. One of the solutions attracting particular interest is sodium-based battery technology.

Sodium-ion batteries could have numerous advantages over conventional and widely used lithium-based batteries. Most notably, as is abundant on our planet and can be easily sourced, they could be affordable and easy to produce on a large-scale.

Despite their possible advantages, most developed so far exhibited low energy densities, due to the relatively large atomic size of sodium and its considerable weight. Typically, these batteries exhibit energy densities below 160 Wh kg-1, which is significantly lower than that of .
