Factors that affect cycle-life and possible degradation mechanisms of a Li-ion cell based on LiCoO2
Soo-Seok Choi,Hong S. Lim +1 more
TL;DR: In this paper, an extensive test has been conducted on a lithium-ion (Li-ion) cell under a variety of cycling conditions in order to evaluate factors that affect its cycle-life.
Journal ArticleDOI
Capacity Fading Mechanisms on Cycling a High-Capacity Secondary Sulfur Cathode
TL;DR: In this article, the cycle life and capacity fading mechanisms of secondary sulfur electrodes prepared by two different electrode fabrication methods were studied in an effort to improve the energy density of the cathode.
Journal ArticleDOI
High-density positive electrodes containing carbon nanotubes for use in Li-ion cells
TL;DR: In this paper, multi-walled carbon nanotubes (MWNT) is used as a conducting agent in a high-density cathode for a Li-ion cell and the results from ac impedance and scanning electron microscopy (SEM) studies indicate that the improved performance of the former electrode is due largely to the resilience of the MWNT aggregates that form conductive bridges between particles of the active material.
Journal ArticleDOI
Effects of metal oxide coatings on the thermal stability and electrical performance of LiCoCO2 in a Li-ion cell
TL;DR: In this article, the effects of MgO and Al2O3 coatings on the electrical properties of LiCoO2 cathode material on the thermal stability (differential scanning calorimetry (DSC)) of the charged cathode, and on the safety characteristics of 18650 Li-ion cells were made.
Journal ArticleDOI
Performance of Li-ion cells with new electrolytes conceived for low-temperature applications
TL;DR: In this article, a number of ternary electrolytes containing a cyclic carbonate (ethylene carbonate), a linear carbonate, a DMC, a diethyl carbonate or an ethylmethyl carbonate were compared to a low-temperature freezing solvent.
