Micro-Supercapacitors

for IoT

Micro-supercapacitors offer energy densities comparable to micro-lithiumion batteries , but with one hundred times more power density and an ability to be recharged in three seconds . These devices have a range of potential applications , including electric vehicles and wearable electronics .

Competitive Advantage

• Bulk intercalative charge storage allows high energy density and low self-discharge
• Dual-carrier transfer renders high power capability
• Based on neutral aqueous electrolyte with high environmental compatibility

Impact

• Improved lifetime , stability and power density for electric vehicle applications
• Facilitating maintenance-free biosensors , mobile environmental sensors , wearable electronics and nanorobotics

Successful Applications

• Lab-demo coin-type cell developed
