Rechargeable lithium-ion (Li-on) cells require a precise charging voltage for maximum performance. The battery chemistry, of which there are many, determines the optimum charge voltage. Two of the more common charging voltages are 4.1V±50 mV and 4.2V±50mV per cell.Fran Hoffart...
Li-ion batteries (LIBs) for electric vehicles and aviation demand high energy density, fast charging and a wide operating temperature range, which are virtually impossible because they require electrolytes to simultaneously have high ionic conductiv
Theory of dissociative charge exchange in ion-molecule collisions Dissociative charge exchange is one of the many processes resulting from vibronic transitions in ion-molecule collisions. Its particular interest lies in t... Sidis,V. - 《Journal of Physical Chemistry》 被引量: 63发表: 1989年 Rate...
The solid-solution range, which is reduced at higher current by the rate of transfer of the working ion across electrode/electrolyte interfaces and within a host, limits the amount of charge per electrode formula unit that can be transferred over the time t = t(I). Moreover, the difference...
The operation of lithium-ion batteries involves electron removal from and filling into the redox orbitals of cathode materials, experimentally probing the orbital electron population thus is highly desirable to resolve the redox processes and charge compensation mechanism. Here, we combine quantitative conv...
