Synergistic Effect of Blended Components in Nonaqueous Electrolytes for Lithium Ion Batteries

Data-Driven Analysis of High-Throughput Experiments on Liquid Battery Electrolyte Formulations: Unraveling the Impact of Composition on Conductivity

“…14,15 Common electrolyte formulations consist of lithium conducting salt such as lithium hexafluorophosphate (LiPF6) and solvent mixtures comprising cyclic carbonates like ethylene carbonate (EC) and propylene carbonate (PC) with linear organic carbonates like dimethyl carbonate (DMC), ethyl methyl carbonate (EMC) and diethyl carbonate (DEC) and provide desirable electrochemical properties for Li-ion batteries. [16][17][18][19][20][21] Here we perform HT impedance spectroscopic experiments on LiPF6-based electrolyte formulations containing EC and EMC as solvent mixture and vinylene carbonate (VC) as functional additive/co-solvent to determine ionic conductivities of resulting electrolyte formulations and develop a data driven model to predict ionic conductivities for variable electrolyte compositions. All data are extracted from HT experiments with conducting salt, solvent/co-solvent, additive compositions and temperature as features and ionic conductivity as target quantity.…”

In situpolymerization process: an essential design tool for lithium polymer batteries

“…1M LiPF 6 in EC: DMC is a classic example of a widely used organic LE. 20 Porous single-or multilayer polyolefin sheets (e.g., Celgard) or glass-fiber mats are often used as the separator. 21,22 Further, LIB electrodes also contain binders, 23 conducting additives, [24][25][26] and current-Affording the future energy demands for high energy applications like long-range EVs and grid-storage, the energy density of state-of-the-art LIBs should be increased beyond a value of > 500 WhKg -1 .…”

Ternary-salt gel polymer electrolyte for anode-free lithium metal batteries with an untreated Cu substrate

“…23,24 Studies have indicated that systems containing multiple lithium salts result in more uniform and stable SEI lms because the merits of these salts are combined. 25,26 In addition, many researchers have investigated ether-based electrolytes because they have lower reactivity with Li metal than do carbonate electrolytes. 27,28 The decomposition of ether-based electrolytes leads to the formation of a exible oligomeric SEI at the Li metal surface, which accommodates the morphology and volume changes of Li during cycling.…”
