Keywords: lithium-ion capacitors; LIC, LICs, lithium-ion supercapacitor safety; high-voltage range capacitors. Lithium-ion capacitors are a hybrid between lithium-ion batteries and Electric Double Layer Capacitors (EDLC). Not much work has been carried out or published in the area of LICs.
The lithium-ion capacitor combines a negative electrode from the battery, composed of graphite pre-doped with lithium-ions Li+, and a positive electrode from the supercapacitor, composed of activated carbon. This allows the LIC to acquire a higher energy density than the SC, while conserving a high power density and a long lifetime.
Lithium-ion capacitors offer superior performance in cold environments compared to traditional lithium-ion batteries. As demonstrated in recent studies, LiCs can maintain approximately 50% of their capacity at temperatures as low as -10°C under high discharge rates (7.5C).
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.
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.
Also, just to further illustrate how you are going down the wrong path, take a look at a typical Lithium Ion charger, such as bq25601, and you will see the charge profile is dependent on temperature. If you are building a voltage regulator charging circuit into a customer product, it will not be safe.
