10 New Supercapacitor Companies | StartUs Insights
In this segment, we explore 10 new supercapacitor companies. Some of these firms manufacture graphene-based supercapacitors with increased
Lithium Ion Capacitor Applications for lithium-ion capacitors (LIC) are similar to ultracapacitors (UC) where long life, highly reliable, maintenance-free energy storage is required for a product or system. Various types of UPS systems, peak power delivery, voltage sag compensation and hybrid energy storage systems are a few examples.
LIC's have higher power densities than batteries, and are safer than lithium-ion batteries, in which thermal runaway reactions may occur. Compared to the electric double-layer capacitor (EDLC), the LIC has a higher output voltage. Although they have similar power densities, the LIC has a much higher energy density than other supercapacitors.
Some LIC's have a longer cycle life but this is often at the cost of a lower energy density. In conclusion, the LIC will probably never reach the energy density of a lithium-ion battery and never reach the combined cycle life and power density of a supercapacitor.
The table below compares major characteristics of double-layer capacitors, LIC and lithium ion batteries. Compared to a double-layer capacitor, the LIC has similar life and power performance with the added benefits of higher energy density, low self-discharge and higher cell voltage.
