Abstract

The impact of calendering process on the geometric characteristics and electrochemical performance of LiNi1/3Mn1/3Co1/3O2 (NMC) electrode was investigated in this study. The geometric properties of NMC electrodes with different calendering conditions, such as porosity, pore size distribution, particle size distribution, specific surface area and tortuosity were calculated from the computed tomography data of the electrodes. A synchrotron transmission X-ray microscopy tomography system at the Advanced Photon Source of the Argonne National Laboratory was employed to obtain the tomography data. The geometric and electrochemical analysis show that calendering can increase the electrochemically active area, which improves rate capability. However, more calendering will result in crushing of NMC particles, which can reduce the electrode capacity at relatively high C rates. This study shows that the optimum electrochemical performance of NMC electrode at 94:3:3 weight ratio of NMC:binder:carbon black can be achieved by calendering to 3.0 g/cm3 NMC density.

Quantitative Microstructure Characterization of a NMC Electrode

Journal Article Usseglio-Viretta, François; Smith, Kandler - ECS Transactions (Online)

Performance of lithium-ion batteries (LIBs) is strongly influenced by the porous microstructure of their electrodes. In this work, 3D microstructures of calendared and un-calendared positive electrode LiNi1/3Mn1/3Co1/3O2 (NMC) have been investigated in order to extract relevant properties useful for battery modeling. Transport (volume fraction, connectivity, particle size and tortuosity) and electrochemical (specific surface area) properties have been calculated for the pore and the active material. Special attention has been paid to determine the size of the so-called representative volume element (RVE) required to be statistically representative of the heterogeneous medium. Several parameters have been calculated using a panel of differentmore »« less

Thermal and electrochemical characterization of MCMB/LiNi{sub 1/3}Co{sub l/3}Mn{sub l/3}O{sub 2} using LiBoB as an electrolyte additive.

Journal Article Lu, W; Chen, Z; Joachin, H; ... - J. Power Sources

The gas generation associated with the use of the lithium bis(oxalate)borate--(LiBoB) based electrolyte at the elevated temperature were detected in the pouch cell (MCMB/LiNi1/3Co1/3Mn1/3O2 with 10% excess Li), which might prevent the LiBoB usage as a salt. However, the cell capacity retention was improved significantly, from 87 to 96% at elevated temperature, when using LiBoB as an electrolyte additive. The capacity fade during cycling is discussed using dQ/dE, area specific impedance, and frequency response analysis results. Most of the capacity loss in the cell is associated with the rise in the cell impedance. Moreover, results from the differential scanning calorimetrymore »« less

Analysis of geometric and electrochemical characteristics of lithium cobalt oxide electrode with different packing densities

Journal Article Lim, Cheolwoong; Yan, Bo; Kang, Huixiao; ... - Journal of Power Sources

In order to investigate geometric and electrochemical characteristics of Li ion battery electrode with different packing densities, lithium cobalt oxide (LiCoO₂) cathode electrodes were fabricated from a 94:3:3 (wt%) mixture of LiCoO₂, polymeric binder, and super-P carbon black and calendered to different densities. A synchrotron X-ray nano-computed tomography system with a spatial resolution of 58.2 nm at the Advanced Photon Source of the Argonne National Laboratory was employed to obtain three dimensional morphology data of the electrodes. The morphology data were then quantitatively analyzed to characterize their geometric properties, such as porosity, tortuosity, specific surface area, and pore size distribution.more »« less

High-Speed Fabrication of Lithium-Ion Battery Electrodes by UV-Curing

Journal Article Xue, Zheng; Hu, Libo; Amine, Khalil; ... - Energy Technology

In this study, UV-curing was investigated as an alternative method to provide fast production of composite cathodes and significantly reduce the time and energy required for solvent removal in lithium-ion battery fabrication. To serve our purpose, low-molecular-weight polysiloxane acrylate (PSA) was designed and synthesized from a polysiloxane epoxide precursor. In the presence of the acrylic acid additive LiNi1/ 3Mn1/3Co1/3O2 (NMC), electrode laminates containing 10 wt% PSA binder were successfully fabricated by UVcuring. The cured electrode exhibited good mechanical and electrochemical properties. At current rates up to C/3, the cell performance of the UV-cured NMC electrode was comparable to that ofmore »« less
