I Degradation Reactions in SONY - Type Li - Ion Batteries
.Thermal instabilities were identified in SONY-type lithium-ion cells and correlated with interactions of cell constituents and reaction products. Three temperature regions of interaction were identified and associated with the state of charge (degree of Li intercalation) of the cell. Anodes were shown to undergo exothermic reactions as low as 100°C involving the solid electrolyte interface (SE...
متن کاملNanomaterials Meet Li-ion Batteries.
Li-ion batteries are used in many applications in everyday life: cell phones, laser pointers, laptops, cordless drillers or saws, bikes and even cars. Yet, there is room for improvement in order to make the batteries smaller and last longer. The Fromm group contributes to this research focusing mainly on nanoscale lithium ion cathode materials. This contribution gives an overview over our curre...
متن کاملVoltage increase of aqueous lithium-ion batteries by Li-ion conducting Li1.5Al0.5Ge1.5(PO4)3 glass-ceramic
In this research, a lithium ion conducting lithium aluminum germanium phosphate (LAGP) glass-ceramic with a formula of Li1.5Al0.5Ge1.5(PO4)3 was synthesized by melt-quenching method and subsequent crystallization at 850 °C for 8 h. The prepared glass-ceramic was characterized using X-ray diffraction analysis (XRD) and field emission scanning electron microscopy (FESEM). The XRD patterns exhib...
متن کاملHigh performance silicon nanoparticle anode in fluoroethylene carbonate-based electrolyte for Li-ion batteries.
Electrodes composed of silicon nanoparticles (SiNP) were prepared by slurry casting and then electrochemically tested in a fluoroethylene carbonate (FEC)-based electrolyte. The capacity retention after cycling was significantly improved compared to electrodes cycled in a traditional ethylene carbonate (EC)-based electrolyte.
