Two-cation competition in ionic-liquid-modified electrolytes for lithium ion batteries

Article Abstract:

Investigation on the observation that when ionic liquids are added to electrolytes the performance of lithium ion cells becomes poor is carried out on the basis of the kinetics of ionic diffusion. Results suggest that the poor C-rate performance of lithium ion cells containing ionic liquids as an electrolyte component can be attributed to the two-cation competition between Li(super +) and butyldimethylimidazolium hexafluorophosphate (BDMI)(super +).

Lithium secondary batteries using modified-imidazolium room-temperature ionic liquid

Article Abstract:

Highly reversible, safe lithium secondary batteries that use imidazolium-cation-based room-temperature ionic liquid as an electrolyte and lithium metal as an anode material were realized by the molecular design. An electron-donating substituent was introduced to promote charge delocalization in the imidazolium cation of room-temperature ionic liquids to achieve higher reduction stability.

Synthesis of mangenese oxide electrodes with interconnected nanowire structure as an anode material for rechargeable lithium ion batteries

Article Abstract:

Nanosized manganese oxide electrodes consisting of interconnected nanowires are electrochemically synthesized at room temperature without any template and catalyst. In comparison to the traditional graphite materials used as anode materials for lithium storage, the synthesized anode material shows much larger capacity.
