With the roll-out of renewable energies, highly-efficient storage systems are needed to be developed to enable sustainable use of these technologies. For short duration lithium-ion batteries provide the best performance, with storage efficiencies between 70 and 95%. Hydrogen based technologies can be developed as an attractive storage option for longer storage durations.
Therefore, in order to achieve low cost and predominant charge storage capacity, the focus should not only limited to synthesis, fabrication and modification approaches, but also on enhancing the electrode-substrate compatibility, controlling the size, phase of the material, morphology, pore size and inorganic-organic hybridization strategy.
A commercial energy storage LFP battery with a nominal capacity of 120 Ah is used in this study, and the typical parameter values are shown in Table 1. Table 1. Typical parameters of the 120 Ah LFP battery. The experimental platform for the battery is shown in Fig. 1.
The rated power of the energy storage battery used in the experiment is 192 W. Set the power response of the battery to 192 W multiplied by the normalized signal, and then divide the power by the nominal voltage of 3.2 V to obtain the current fluctuation signal. Fig. 5 shows the FR operating condition.
The battery capacity test is performed to determine the standard capacity value of the battery. The battery is charged at 25 °C at 1/3 current rate (C) of the nominal capacity at constant current and constant voltage (CCCV) up to a cutoff voltage of 3.65 V until the current is reduced to 1/20C (6 A).
Conventional energy storage systems have played a pivotal role in managing energy reserves, maintaining reliability, and ensuring the robustness of energy networks. Various technologies have been developed and implemented over the years, each with unique advantages and limitations.
Based on the test results of a commercial 120 Ah LFP energy storage battery, four typical battery models are established, including the SRCM, the hysteresis voltage reconstruction model (HVRM), the OSHM, and the NNM.
