Revealing SEI Formation and Evolution at the Li Anode/Liquid Electrolyte Interface in Li-ion Batteries by in situ Fourier Transform Infrared Spectroscopy
… electrolyte systems were tested: 1.2 M LiPF₆ in EC, 1.0 M LiPF₆ in EMC, and LP57 (1.0 M LiPF₆ in EC:EMC (3/7 vol %)). Using the spectroelectrochemical cell, FTIR measurements for first plating step and cycled cells (up to 50 cycles) were collected to look for new species formation. In …

Molekulare und histologische Untersuchungen zur gustatorischen Fettwahrnehmung des Menschen
… der bei Nagetieren gefundenen Lipase F (LIPF), jedoch der eng verwandten Lipasen K, M und N in den serösen Zellen der VED. In-silico-Untersuchungen der Sekundär- und Tertiärstrukturen zeigten die hohe Ähnlichkeit zu LIPF, erwiesen aber auch Unterschiede in den Bindungstaschen der Enzyme, …

Understanding the intrinsic electrochemistry of ni-rich layered cathodes
… electrolyte, with the standard commercial salt LiPF<sub>6</sub> suffering from exothermic decomposition at high voltages and temperatures. Substituting LiPF<sub>6</sub>with LiBF4 suppressed NCA surface degradation and the dissolution of the transition metals into the electrolyte which is …

Understanding Transition Metal Dissolution from Battery Materials with Solution NMR Methods
… ³¹P, and ⁷Li NMR measurements are performed on LiPF₆ solutions containing model transition metal compounds or metals dissolved from cathode materials. NMR of transition metal-contaminated battery electrolyte solutions is used to quantify dissolved metals at micromolar concentrations; determine …

Tailoring Electrolytes for Extreme Temperatures in Rechargeable Aluminum and Lithium-Ion Batteries
… the thermally unstable electrolytes based on LiPF₆—which leads to capacity fade, transition metal leaching, and increased risk of failure. These challenges underscore the need for new electrolyte systems that are both thermally and electrochemically stable under extreme conditions.</p> <p>In …

Composite Gel Polymer Electrolyte for Lithium Ion Batteries
… as ionic conductors, and LiClO<sub>4</sub>+LiPF<sub>6</sub> as lithium salts were fabricated. CGPE was coated on an O2-plasma treated trilayer polypropylenepolyethylene- polypropylene (PP) membrane separator using solution casting technique. In acidic CGPE, the mixture of acid treated …

Layer-by-layer assembled carbon nanotube nanostructures for high-power and high-energy lithium storage
… comparable energy and power performance in LiPF 6, LiBF 4, and LiClO4 electrolyte, and also in non-lithium containing TEABF 4 electrolyte, indicating that surface redox is independent of electrolyte solvent or anion, and suggesting that functional groups can be a versatile charge storage …

Bildgebende Multiparameter-Lasermessungen in komplexen technischen Strömungs- und Verbrennungsprozessen
… the reaction zone is visualized by means of OH-LIPF and that of the sooting zone is measured semi-quantitatively via LII. The extinction limits as a function of the flame curvature are determined. At the extinction limit the structure of the curved flame is strongly influenced by the orientation …
