Dual intercalation secondary battery – Using intercalation of ions into both electrodes simultaneously
The here presented technology offers electrochemical energy storage cells, in which positive and negative ions can be intercalated into both anode and cathode respectively. The electrodes both can consist of graphite or the anode can be made of Li4Ti5O12. Ionic liquids are used as electrolyte to solve the lithium salt and the anions are formed by BOB- or TFSI-.
Commercial Opportunities: With this new concept, cost effective and environmentally friendly electrochemical energy storage devices can be realized. The use of transition metals and fluoride compounds can be avoided. Compared to existing solutions with similar requirements a higher specific capacitance can be reached and an extended temperature range is accessible. By use of LTO as anode material a cell voltage of 3.5 V can be reached. Suitable applications can be found in local energy storage systems in smart grid scenarios for the compensation of peak power fluctuations due to the increasing energy production from renewable sources.
