Optical Detection and Modeling of Lithium Deposition on Copper Current Collectors

Advanced Materials Interfaces, EarlyView.
ABSTRACT Understanding lithium (Li) deposition on copper (Cu) substrates is essential for improving the performance and lifetime of zero–excess lithium metal batteries. In this study, Li deposition was investigated under realistic coin–cell conditions using complementary scanning electron microscopy and laser scanning microscopy. A semi–automatic image

Antiferromagnetic Dimers of Ni(II) in the S=1 Spin-Ladder Na_2Ni_2(C_2O_4)_3(H_2O)_2

, 2006
We report the synthesis, crystal structure and magnetic properties of the S=1 2-leg spin-ladder compound Na_2Ni_2(C_2O_4)_3(H_2O)_2. The magnetic properties were examined by magnetic susceptibility and pulsed high field magnetization measurements.

In‐Operando FTIR Study to Investigate the Effect of Varying Lithium Salts on Solid Electrolyte Interface (SEI) Evolution in Lithium Metal Batteries

Advanced Science, EarlyView.
A clear correlation between electrolyte salt chemistry and Solid Electrolyte Interface (SEI) performance in lithium metal batteries is established using in operando FTIR spectroscopy. This study shows that LiTFSI instantaneously forms a robust, inorganic organic hybrid SEI (LiF, Li3N, Li2O, ROCO2Li, ROLi) that minimizes overpotential, while less ...

Interface Construction via Scavenging Oxygen Species Enables High‐Performance Li‐Rich Layered Oxide Cathode

Advanced Science, EarlyView.
To inhibit electrolyte decomposition by nucleophilic attack in carbonate electrolyte, LiBOB and LiDFOP with strong oxygen scavenging ability are selected to quench reactive oxygen species and following construct a robust CEI film on the LRLO cathode. The electrochemical performance of the LRLO cathode is largely improved, attributed to decomposition ...

Enhanced Fast‐Charging Performance of High‐Mass‐Loading Mn‐Rich Li[Mn1‐xFex]PO4 Cathodes via LiF‐Less Cathode–Electrolyte Interphase

Advanced Energy Materials, EarlyView.
LiF‐rich@LMFP develops a CEI enriched with electronically and ionically insulating LiF that impedes interfacial charge transfer during fast charging. By suppressing interfacial LiF formation, LiF‐less@LMFP accelerates Li+ exchange and lowers overpotentials, delivering 1.6‐fold higher capacity at 5C and ∼87% retention after 100 cycles under practical ...
