Nickel-Cobalt Layered Double Hydroxide (NiCo-LDH) Treated Nickel Foam Electrodes
Supercapacitors are transforming the landscape of energy use. By rapidly charging and discharging large amounts of energy, relative to conventional batteries and capacitors, these devices are improving mobile electronics, automotive and energy grid technologies.
At the heart of supercapacitor technology is an electrically active material, which may store and release energy quickly.
The quality of this material is distinguished by three main characteristics:
1. Capacitance (Farads per gram)
2. Max current rating (Amperes per gram)
3. Stability (# of charge/discharge cycles retaining ≥90% performance)
Description of Technology
Researchers at CARES (Cambridge Centre for Advanced Research and Education in Singapore) have recently developed a new, cost efficient process for the synthesis of high performance layered double hydroxide electrodes.
This new material is significantly higher performing than the industry standard (activated carbon) in terms of charging rate and specific capacitance.
