In Situ Synthesis of the Peapod‐Like Cu–SnO₂@Copper Foam as Anode with Excellent Cycle Stability and High Area Specific Capacity (Adv. Funct. Mater. 33/2021)

Geometric Engineering of Porous PtCu Nanotubes with Ultrahigh Methanol Oxidation and Oxygen Reduction Capability

“…The Cu 2p 3/2 and Cu 2p 1/2 peaks are split to Cu 0 and Cu 2+ . Compared to the binding energy measured on bulk Cu (931.8 and 951.6 eV), [ 33 ] the Cu 0 2p of H‐PNTs, A‐PNTs, and S‐PNTs shift positively by 0.40, 0.70, and 0.43 eV, respectively. H‐PNTs show an obvious satellite peak owing to the oxidation of surficial Cu in the air, while the oxidation could be hardly seen in A‐PNTs and S‐PNTs due to the high surficial Pt content.…”

Vertical‐Channel Cathode Host Enables Rapid Deposition Kinetics toward High‐Areal‐Capacity Sodium‐Chlorine Batteries

“…[1][2][3][4][5] Devising new battery types with high specific and areal capacity and high energy density materials DOI: 10.1002/smll.202310978 has become increasingly important. [6][7][8][9][10] Among various battery paradigms, including Li-oxygen (Li-O 2 ), [11,12] Li-sulfur (Li-S), [13,14] sodium-sulfur (Na-S) batteries, [15,16] etc., the discovery of rechargeable alkalimetal (Li/Na)-Cl 2 batteries derived from the primary (Li/Na-SOCl 2 ) types have received intensive attraction due to its high energy density and potential use in professional electronics, military, and utility metering applications. [17][18][19][20] In a typical Na-Cl 2 battery system reported by the Dai group, the redox reactions of Cl 2 /Cl − in the micropore carbons and Na/Na + (or Li/Li + ) on the anode contribute to the majority of reversible capacity of the battery, delivering a discharge voltage of ≈3.5 V. However, the practical impletion of the alkali-metal-Cl 2 battery is still hindered by the relatively inferior electrochemical performance related to poor cycling lifespan and low areal capacity.…”
