The lithium-ion battery (LIB) has become the most widely used electrochemical energy storage device due to the advantage of high energy density.
A solar panel typically charges a battery that powers an LED light. A charge controller ensures the solar panel properly charges the battery, and a DC-DC LED driver circuit connects the battery to the light. An ambient light sensor alerts the system when it''s dark enough to turn the light on, and to turn it back off again as the sun comes up.
In recent publications, we have demonstrated a new type of energy storage device, hybrid lithium-ion battery-capacitor (H-LIBC) energy storage device [7, 8]. The H-LIBC technology integrates two separate energy storage devices into one by combining LIB and LIC cathode materials to form a hybrid composite cathode.
