US Patent Application for SYSTEM FOR AN IONIC LIQUID

To improve the stability and reduce potential safety hazards of high energy density cells without compromising the system performance, the electrolyte system 140 is preferably chemically and electrochemically stable against both the anode 110 and cathode 120

Fluorinated Solid

Integrating lithium metal anode with high-voltage cathode has been regarded as a promising high-energy-density battery system. Fluorinated solid-electrolyte interphase emerges as a promising strategy to promote practical applications of high-voltage Li-metal batteries. This perspective sheds light on the challenges and possible directions for further development of fluorinated SEI in practical

High

Polymeric aromatic amines were shown to be very promising cathodes for lithium-ion batteries. Surprisingly, these materials are scarcely used for designing post-lithium batteries. In this Letter, we investigate the application of the high-voltage poly(N-phenyl-5,10-dihydrophenazine) (p-DPPZ) cathodes for K-ion batteries. The designed batteries demonstrate an impressive specific capacity of 162

The devices exhibited sub-ppm sensitivity and high selectivity toward amines as well as good stability to air, moisture, and time. The application of these chemiresistors in the detection of various biogenic amines (i.e. putrescine, cadaverine) and in the monitoring of spoilage in raw meat and fish samples (chicken, pork, salmon, cod) over several days was also demonstrated.

Critical effects of electrolyte recipes for Li and Na metal

Electrolyte recipes hold the key in stabilizing Li/Na metal batteries in terms of solid-electrolyte interphase (SEI) modulation, dendrite inhibition, and dead Li/Na elimination. Here, we knock down the critical effects of the newly developed electrolyte recipes for Li/Na metal batteries into four categories—(1) the concentration effect, (2) the fluorination effect, (3) the synergistic effect

In addition, it is found that the morphology of Li anodes is dependent on the cathode structures. An ammonium additive enables homogeneous surface of cathode and Li anode and extended cycle life. 2017 J. Zhang, Z. Yang, I. A. Shkrob, R. S. Assary, S. Tung

Iron(III) fluoride (FeF3) is considered a potential cathode for sodium-ion batteries (SIBs) due to its high capacity and low cost. However, particle pulverization upon cycling generally results in rapid degradation of its structure and capacity. Here, we introduce a free

2018/6/12Intercalation of Li in graphite leads to stable systems with calculated intercalation energies of -0.2 to -0.3 eV/Li atom, (referred to bulk graphite and Li metal). The fully loaded stage 1 and stage 2 compounds LiC6 and Li1 /2C6 are stable, corresponding to two-dimensional √{3 }√{3 } lattices of Li atoms intercalated between two graphene planes.

This study focuses on δ-MnO2 with nanoflower structure supported on graphite flake, namely MNG, for use as an intercalation host material of rechargeable aqueous ZIBs. Pristine δ-MnO2 nanoflowers and MNG were synthesized and examined using X-ray diffraction,

Advanced carbon materials: electrochemical aspects

Graphene was made from flake graphite by intercalation, exfoliation (at 200-300 oC in vaccum condition), and heat reduction. As prepared graphene was added into different cathode materials in LIB system, we found that it was only 20-50 wt.% used to replace current super P or carbon nanotubes, thus the volume energy density might be improved as 3-5% and enhanced the fast charge-discharge
