Definitions
- the present invention relates to a bicyclic triol borate and its use in an electrolyte composition.
- the present invention relates in particular to the use of a bicyclic triol borate in an electrolyte composition in electrochemical supercapacitors, for example in double-layer capacitors in electric motors.
- Electromobility requires high-performance energy storage systems. Rapid load changes in electromobile systems lead to a drop in performance and a shortening of the service life of electrochemical energy storage devices. Therefore, high-performance electrical storage buffers are required to relieve the burden on electrochemical energy storage in electromobile systems. For vehicles with electric motors, new materials are required for more efficient energy storage. The desired new materials should guarantee fast and permanent availability of drive energy. In particular, novel electrolyte compositions in capacitors with increased storage capacity and performance would be desirable.
- electrochemical supercapacitors An efficient storage and conversion of energy in electric motors is possible through electrochemical supercapacitors.
- electrochemical double-layer capacitors EDLC
- the charge capacity and performance of supercapacitors are significantly influenced by the electrolyte composition.
- the previously provided electrolyte compositions in supercapacitors are based predominantly on strongly acidic or basic aqueous salt solutions.
- the electrolyte compositions provided hitherto have a limited charge capacity, a limited electrochemical window and an undesirable thermal expansion when heated.
- previously provided electrolyte compositions in supercapacitors are characterized by the fact that a relatively high proportion of solvent is used. This reduces the proportion of conductive ions, which has a negative effect on the conductivity of the energy store.
- WO 2015/007659 A1 describes the use of reactive lithium tetraalkoxyborates in electrolytes.
- the electrolyte composition contains the reactive lithium tetraalkoxyborates only as an additive.
- the electrolyte composition has a high proportion of 60-99.98% by weight of solvent and a low proportion of conductive salts. This limits the performance of an energy store.
- the electrolyte composition contains ions which can have an undesirably high reactivity.
- the electrolyte composition should be distinguished in particular by an increased charge capacity, it being possible to produce the electrolyte composition from readily available raw materials and at low cost.
- the objects are achieved by the subject matter of the claims.
- the objects are achieved in particular by a bicyclic triol borate according to claim 1. They are also achieved by the use of bicyclic triol borates in an electrolyte composition in an energy store, in particular a capacitor.
- the bicyclic triol borates and electrolyte compositions according to the invention are characterized in particular by 1) a high electrolyte concentration or ion density, 2) a low viscosity for low internal resistance, 3) a wide voltage window with high electrochemical stability and 4) a small effective radius for close electrode contact . They are also easy and inexpensive to manufacture.
- a great advantage of the bicyclic triolobate salts is that the properties 1) - 4) can be varied and optimized for the particular application due to the substituent pattern on the cation or along the main axis of the cage molecule. There is thus a wide range of customization options that the conductive salts and electrolyte compositions used to date do not offer.
