Description
CONTEXT
Batteries as Lithium Ion Batteries (LIB) usually have good performance in terms of energy density. On the contrary, supercapacity are known to exhibit good performance in terms of power density as could be seen in typical Ragonne plot hereunder.
TECHNICAL DESCRIPTION
This invention describes compound that could be used as additives in LIB electrolyte. These compound fill the gap between battery and supercapacitor.
BENEFITS
- Enhancement of power for batteries
- Enhancement of energy for supercapacitor
- “Hybride” electrode between battery and supercapacitor could be used and their performances are enhanced (power and energy)
- Low cost manufacturing of electrode
- Could be used with organic materials.
INDUSTRIAL APPLICATIONS
The main application of this invention are batteries and supercapcitors.
DEVELOPMENT STAGE
Tests done demonstrate that energy and power delivered are multiply by 1.5 – 2.5 compared to the same system without the additives.
