Sodium-ion EV battery breakthrough pushes performance to theoretical limits

> “The binder we chose, carbon nanotubes, facilitates the mixing of TAQ [bis-tetraaminobenzoquinone] crystallites and carbon black particles, leading to a homogeneous electrode,” explained Chen.

"High-Energy, High-Power Sodium-Ion Batteries from a Layered Organic Cathode" (2025) https://pubs.acs.org/doi/10.1021/jacs.4c17713 :

> It exhibits a high theoretical capacity of 355 mAh/g per formula unit, enabled by a four-electron redox process, and achieves an electrode-level energy density of 606 Wh/kg (90 wt % active material) along with excellent cycling stability,
