Ultra‐Densified TiO₂(B) Anode With Fluid‐Like Compressibility: Enhancing Volumetric Capacity for High‐Performance Supercapacitors Open
This study develops a highly densified bronze‐type TiO₂ (TiO 2 (B)) anode to enhance the volumetric energy and power density of supercapacitors. By integrating ultracentrifugation with strategic carbon reduction via annealing, a TiO₂(B) an…

Ruddlesden–Popper Y <sub>2</sub> Ti <sub>2</sub> O <sub>5</sub> S <sub>2</sub> /SWCNT composite anode: durable cycling and ultrafast lithium-ion storage for hybrid supercapacitors Open
Cation-deficient Y 2 Ti 2 O 5 S 2 with alternating perovskite-like TiO 5 S slabs and rock-salt [Y 2 S 2 ] 2+ layers exhibits excellent rate capability up to 230C and retains 95% capacity after 1,000 cycles, showing great promise as a durab…

Ultrafast Nanocrystalline‐TiO<sub>2</sub>(B)/Carbon Nanotube Hyperdispersion Prepared via Combined Ultracentrifugation and Hydrothermal Treatments for Hybrid Supercapacitors Open
Anisotropically grown (b-axis short) single-nano TiO2 (B), uniformly hyper-dispersed on the surface of multiwalled carbon nanotubes (MWCNT), was successfully synthesized via an in situ ultracentrifugation (UC) process coupled with a follow…
