The specific energy of the supercapacitor ranges from 1Wh/kg to 30Wh/kg, 10–50 times less than Li-ion. The discharge curve is another disadvantage. Whereas the electrochemical battery delivers a steady voltage in the usable power band, the voltage of the supercapacitor decreases on a linear scale, reducing the usable power spectrum.
Batteries release electricity by converting the stored chemical energy back into electrical energy through a chemical reaction that creates a flow of electrons. What are the main components of a battery?
The voltage is generated by the charging and discharging process of the Li-ions from the anode and cathode. Reactions shown also apply to solid-state batteries, although the choice of material is atypical here, Own illustration. During discharge, the Li-ions migrate from the anode to the cathode. LCO is a cathode with a layered structure.
These electrons flow through the external circuit (the device you’re powering) towards the cathode, creating an electric current. Meanwhile, ions move through the electrolyte within the battery to balance the charge. This flow of electrons is what powers your device.
When a battery is connected to a device (like a flashlight or phone), a chemical reaction occurs at the anode, releasing electrons. These electrons flow through the external circuit (the device you’re powering) towards the cathode, creating an electric current. Meanwhile, ions move through the electrolyte within the battery to balance the charge.
Batteries store energy in the form of chemical energy. This is achieved through two electrodes—a positive terminal called the cathode and a negative terminal called the anode—separated by an electrolyte. When a battery is not in use, it holds potential energy in these chemical compounds.
Batteries are valued as devices that store chemical energy and convert it into electrical energy. Unfortunately, the standard description of electrochemistry does not explain specifically where or how the energy is stored in a battery; explanations just in terms of electron transfer are easily shown to be at odds with experimental observations.
