- Chemically polished lithium metal anode for high energy lithium metal . . .
Our approach can improve the rate capability of lithium metal batteries with LiFePO 4 cathode for 41 4% at 10 C, as well as the coulombic efficiency up to 99 5% over 350 cycles
- High rate and stable cycling of lithium metal anode - Nature
Herein, we report that the use of highly concentrated electrolytes composed of ether solvents and the lithium bis (fluorosulfonyl)imide salt enables the high-rate cycling of a lithium metal anode
- A redox acceptor–acceptor nitro functionalized naphthalene diimide rGO . . .
This study presents a composite material incorporating naphthalene diimide nitro derivatives (NDI-2NO 2 and NDI-4NO 2) into reduced graphene oxide (rGO) as an anode material for LIBs The inclusion of rGO not only addresses the problem of material dissolution in the organic electrolyte, but also significantly improves the rate performance and
- Lithium metal scrubbing solution for battery testing Naphthalene
This is a chemical polishing reagent that can smooth the surface of lithium metal and remove native surface impurities Treatment of lithium metal with this solution has been shown to improve the cycle life and rate performance of lithium metal batteries
- Lithium-Metal Anodes: Problems and Multiple Solutions Based on Hosts . . .
Develop stable electrolytes to improve the CE of Li metal anode Enable operation of thin Li metal anode in lean electrolyte conditions Develop protective layers separator to protect Li metal against dendrite growth Develop efficient host for Li metal to minimize volume change of Li based anode
- Confronting the Challenges in Lithium Anodes for Lithium Metal . . .
The conventional LiPF 6 ethylene carbonate-ethyl methyl carbonate (EC-EMC) system has been demonstrated incompatible with lithium metal anode, and the lithium metal batteries fail because the porous phase with high resistance gradually form on the anode during the cycling
- Advanced Anodes and Electrode Coating Technology for High Energy . . . - NASA
Coating Technology for High Energy Lithium Ion Batteries Pu Zhang, Robert Sosik, Felix Nunez, based on lithium metal oxide cathode and Si composite anode; capable of being packaged into a wide variety of cell form factors Discharge Rate 0 5C continuous Specific Energy (Wh kg) 240-350 Energy Density (Wh L) 500 -700 Cycle Life* 50-250
- Understanding the Electrochemical Properties of Naphthalene Diimide . . .
Herein, we used 1,4,5,8-naphthalene diimide (NDI) as a model molecule to systematically investigate its intrinsic electrochemical property, including its electrolyte compatibility, maximum capacity, cycling stability, and rate capability in different organic electrolytes
- Engineering of Aromatic Naphthalene and Solvent Molecules to Optimize . . .
The target of this work is to develop an effective chemical prelithiation protocol for boosting the performance of LIB anodes with low charge-discharge Coulombic efficiency
- Keeping in contact with lithium | Science - AAAS
Yoon et al demonstrate a means to mitigate contact loss at the anode–solid electrolyte interface without requiring high stack pressure Adding 5 to 20% of electrochemically inactive sodium metal to the lithium anode prevented the emergence of interfacial voids Instead of vacancies accumulating to form voids, sodium metal dynamically accumulated at the interface (see the figure)
