Month: January 2020
Yi Cui, Seok Woo Lee, Hyun Wook Lee Department of Materials Science and Engineering, Stanford University Silicon is considered one of the most promising anode…
The tortuosity (τ) of the pore structure in a lithium ion battery is a parameter that describes the influence of the morphology of the electrode…
Diagnostic studies of components harvested from high-power LiNi0.8Co0.15Al0.05O2/Graphite lithium-ion cells were conducted to determine the causes of capacity fade and impedance rise exhibited by the…
This site is devoted to lithium battery research aimed at understanding the mechanisms and problems that underlie the workings failure/degradation of Li-ion batteries. There is…
In this research, a Stanford, SLAC, and ALS (Advanced Light Source) team developed synchrotron liquid scanning transmission x-ray microscopy (STXM) to probe the spatiotemporal evolution…
There are relatively few publications that assess capacity decline in enough commercial cells to quantify cell-to-cell variation (failure statistics), but those that do show a…
