Title: Effect of overcharge on Li(Ni _0.5Mn _0.3Co _0.2)O ₂/graphite lithium ion cells with poly(vinylidene fluoride) binder. III — Chemical changes in the cathode

Abstract

Here, 1.5 Ah pouch cells based on Li(Ni _0.5Mn _0.3Co _0.2)O ₂ cathodes and graphite anodes, both containing poly (vinylidene fluoride) (PVDF) binders, were systematically overcharged to 100, 120, 140, 160, 180, and 250% state of charge (SOC), at which point they vented. The cells were subsequently discharged to 0% SOC and disassembled under an inert atmosphere for characterization. A combination of X-ray photoelectron spectroscopy (XPS), scanning-electron microscopy (SEM), energy-dispersive spectroscopy (EDS), ⁶Li SSNMR, and X-ray diffraction (XRD) analysis of the NMC532 cathodes indicates the formation of a thin C- and O-rich cathode electrolyte interphase layer, progressive Li loss above 140% SOC, and retention of the bulk crystal structure at all states of charge.

Effect of overcharge on Li(Ni 0.5 Mn 0.3 Co 0.2 )O 2 /Graphite lithium ion cells with poly(vinylidene fluoride) binder. I - Microstructural changes in the anode

Journal Article Dietz Rago, Nancy ; Bareño, Javier ; Li, Jianlin ; ... - Journal of Power Sources

Cells based on NMC/graphite, containing poly(vinylidene difluoride) (PVDF) binders in the positive and negative electrodes, were systematically overcharged to 100, 120, 140, 160, 180, and 250% state-of-charge (SOC). At 250% SOC the cell vented. Scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) of the anodes showed several state-of-overcharge-dependent trends. Starting at 120% SOC, dendrites appeared and increased in concentration as the SOC increased. Dendrite morphology appeared to be dependent on whether the active material was on the "dull" or "shiny" side of the copper collector. Significantly more delamination of the active material from the collector was seen on themore »« less

Effect of electrolyte composition on rock salt surface degradation in NMC cathodes during high-voltage potentiostatic holds

Journal Article Tornheim, Adam ; Sharifi-Asl, Soroosh ; Garcia, Juan C. ; ... - Nano Energy

Surface degradation of lithium-ion cathodes at high voltages represents a significant barrier to increasing the useable energy of conventional cathodes. Though much work has been focused on mitigating the detrimental effects of such phenomena, the complex and correlated mechanisms involved have made progress difficult. In this paper, the effect of electrolyte identity on surface degradation is examined. LiNi _0.5Mn _0.3Co _0.2O ₂ (NMC532)/Li ₄Ti ₅O ₁₂ (LTO) full cells were constructed using three different electrolytes: a baseline organic carbonate electrolyte, a baseline organic carbonate electrolyte with an oxidizable additive, and a fluorinated carbonate electrolyte. Each system was subjected to amore »« less

Transition-metal redox evolution in LiNi _0.5Mn _0.3Co _0.2O ₂ electrodes at high potentials

Journal Article Qiao, Ruimin ; Liu, Jun ; Kourtakis, Kostantinos ; ... - Journal of Power Sources

The mixed transition-metal layered compound, LiNi _0.5Mn _0.3Co _0.2O ₂ (NMC532), is a promising high-energy cathode material. However, the required high-voltage (>4.3 V) cycling is accompanied by a rapid capacity fade associated with a complex redox mechanism that has not been clarified. Here in this paper, we report soft x-ray absorption spectroscopy of NMC532 electrodes, both pristine and those charged to 4.2, 4.35, or 4.5 V in graphite/NMC532 cells. A quantitative sXAS analysis shows that about 20% of the nickel exists as Ni ⁴⁺ in the as-synthesized NMC532. The Ni redox reaction contributes only to the experimental capacity obtained belowmore »« less
