An object with a high energy density, but low power density can perform work for a relatively long period of time. An example of this type of energy storage is a mobile phone. Its power will last most of the day, but to recharge the device, it must be connected to another power source for an hour or more.

In order to promote the research of green energy in the situation of increasingly serious environmental pollution, dielectric ceramic energy storage materials, which have the advantages of an extremely fast charge and discharge cycle, high durability, and have a broad use in new energy vehicles and pulse power, are being studied.

2. Calculation of Energy Stored in a Capacitor. One of the fundamental aspects of capacitors is their ability to store energy. The energy stored in a capacitor (E) can be calculated using the following formula: E = 1/2 * C * U2. With : E = the energy stored in joules (J) C = capacitance of the capacitor in farads (F)

One of the most important groups of organic PCMs is paraffin wax.
