On the surface of Mars, there are currently two operational rovers that utilize robust Li-ion batteries that have contributed to their demonstrated long life, which exceeded the original mission objective. In early 2004, NASA-JPL successfully landed

We report on solid state 7Li NMR measurements of electrochemically lithiated SnO. At low Li contents (Li/SnO≤2), the results are consistent with the formation of amorphous Li2O. For Li/SnO ratio of 4.3, in addition to the amorphous Li2O phase, ther

Nondestructive methods such as ac impedance spectroscopy and microcalorimetry are used to study the effect of cell cycling on the lithium/electrolyte interface. The reactivity of both uncycled and cycled lithium towards various electrolytes is examin

The overcharge condition in secondary lithium batteries employing redox additives for overcharge protection, has been theoretically analyzed in terms of a finite linear diffusion model. The analysis leads to expressions relating the steady-state over
