An electrochemical cell (battery) with high energy density enabling back up for wind and solar power, typically store low energy of between 1 and 50 kWh of energy, and have historically been based on lead-acid (Pb-acid) chemistry [3]. Pb-acid batteries are well known to last for up to a decade, depending on the depth of discharge.

Progress in the application of renewable energy is facilitated by sustainable development and healthy environment for energy storage devices. The demand of power and its generation via natural sources like solar power, geothermal, biomass, and wind energy has attracted researchers to meet the demand for energy (Aricò et al., 2005aa;
The rapid growth in the capacities of the different renewable energy sources resulted in an urgent need for energy storage devices that can accommodate such increase [9, 10].

Li-air batteries based on Li metal as anode and O 2 as cathode, are regarded as promising energy storage devices because of an ultrahigh theoretical energy density of 3500 Wh kg −1, five to ten times higher of traditional Li-ion batteries.
Energy storage device testing is not the same as battery testing. There are, in fact, several devices that are able to convert chemical energy into electrical energy and store that energy, making it available when required. Capacitors are energy storage devices; they store electrical energy and deliver high specific power, being charged, and
Extensive research has been performed to increase the capacitance and cyclic performance. Among various types of batteries, the commercialized batteries are lithium-ion batteries, sodium-sulfur batteries, lead-acid batteries, flow batteries and supercapacitors.

This paper aims to study the limitations and performances of the main energy storage devices commonly used in energy harvesting applications, namely super-capacitors (SC) and lithium polymer (LiPo) batteries. The self-discharge phenomenon is the main limitation to the employment of SCs to store energy for a long time, thus reducing
Energy storage is the capture of energy produced at one time for use at a later time [1] to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an accumulator or battery. Energy comes in multiple forms including radiation, chemical, gravitational potential, electrical potential
