In reviewing the data in Figure 2, the Li-Ion advantage in gravimetric density is clearly the most striking, almost doubling the Ni-Cd and Ni-MH figures. This means that products powered by Li-Ion cells can be made much lighter without sacrificing run time. Alternately, if the battery weight is kept the same, the ...
WebThen on the second charge/discharge cycle the 4.2V charge limit was reached for a short time, and the potential decayed from 4.16 to 3.86 V. On a longer time scale ( Fig. 2) one can see that the charge/discharge of the battery is close to its dynamic equilibrium on the fourth cycle, the discharge occurring in the 4.17 V- 3.89 V window.
WebThe lithium storage property of SnS-GNS was investigated by galvanostatic charge/discharge cycling at a current density of 100 mA g -1 in the voltage range of 0.01 to 3.0 V. For comparison, bare SnS and GNS were also tested under the same conditions.
