  • Sodium-nickel Chloride Battery experimental transient modelling for energy stationary storage
    Journal of Energy Storage, 2017
    Co-Authors: S. Dambone Sessa, Andrea Necci, Francesco Palone, Roberto Benato
    Abstract:

    The paper presents the analysis of Sodium Nickel Chloride batteries in transient operation, and proposes a simple but very precise model to represent both the transient and steady Battery behaviours. Hence, the main purpose of this model is to foresee the Battery voltage during the most important network services, which require very fast transitions from the Battery charge operation to the discharge one. In order to validate the model, several comparisons between experimental measures and model results are shown.

  • Sodium nickel Chloride Battery steady-state regime model for stationary electrical energy storage
    Journal of Energy Storage, 2016
    Co-Authors: S. Dambone Sessa, Giorgio Crugnola, Stefano Zin, M. Todeschini, Roberto Benato
    Abstract:

    The purpose of this paper is presenting a reliable modelling of sodium-nickel Chloride Battery in order to have a powerful tool which is able to foresee the steady state Battery behaviour in both discharge and charge operations. The proposed modelling approach allows representing both constant current operations and variable charge or variable discharge current ones, but it does not allow passing instantaneously from one Battery mode to another one. This method is based on experimental measures. All the main modelling steps are described and a comparison between the model results and real Battery measures, with the same conditions, is presented. The very good agreement between measures and model confirms the robustness of the approach for steady state applications. The paper proposes to adopt a set of standard Battery measures from which it is possible to infer a simple but very precise modelling structure.

  • A general electric model of sodium-nickel Chloride Battery
    AEIT 2016 - International Annual Conference: Sustainable Development in the Mediterranean Area Energy and ICT Networks of the Future, 2016
    Co-Authors: Roberto Benato, S. Dambone Sessa, Andrea Necci, Francesco Palone
    Abstract:

    The paper presents the analysis of Sodium Nickel Chloride batteries in transient operation, and proposes a very simple but quite precise model to represent both the transient and steady Battery behaviours. The used modelling approach is based on steady state experimental measures. Sodium Nickel Chloride batteries are one of the most promising technologies for electrical energy stationary storage in the high voltage network. Hence, the main purpose of this model is to foresee the Battery voltage during the most important network services, which require very fast transition from the Battery charge operation to the discharge one. In order to validate the model, several comparisons between experimental measures and model results are shown.

  • sodium nickel Chloride Battery technology for large scale stationary storage in the high voltage network
    Journal of Power Sources, 2015
    Co-Authors: Roberto Benato, Giorgio Crugnola, S. Dambone Sessa, Nicola Cosciani, Giuseppe Lodi, Carlo Parmeggiani, M. Todeschini
    Abstract:

    Abstract The extensive application of Sodium–Nickel Chloride (Na–NiCl 2 ) secondary batteries in electric and hybrid vehicles, in which the safety requirements are more restrictive than these of stationary storage applications, depicts the Na–NiCl 2 technology as perfectly suitable for the stationary storage applications. The risk of fire is negligible because of the intrinsic safety of the cell chemical reactions, related to the sodium-tetrachloroaluminate (NaAlCl 4 ) content into the cell, which acts as a secondary electrolyte (the primary one being the ceramic β″-alumina as common for Na-Beta batteries). The 3 h rate discharge time makes this technology very attractive for load levelling, voltage regulation, time shifting and the power fluctuation mitigation of the renewable energy sources in both HV and EHV networks.

  • Application of a Simplified Thermal-Electric Model of a Sodium-Nickel Chloride Battery Energy Storage System to a Real Case Residential Prosumer
    Energies, 2017
    Co-Authors: Fabio Bignucolo, Giorgio Crugnola, Massimiliano Coppo, Andrea Savio
    Abstract:

    Recently, power system customers have changed the way they interact with public networks, playing a more and more active role. End-users first installed local small-size generating units, and now they are being equipped with storage devices to increase the selfconsumption rate. By suitably managing local resources, the provision of ancillary services and aggregations among several end-users are expected evolutions in the near future. In the upcoming market of household-sized storage devices, sodium-nickel Chloride technology seems to be an interesting alternative to lead-acid and lithium-ion batteries. To accurately investigate the operation of the NaNiCl2 Battery system at the residential level, a suitable thermoelectric model has been developed by the authors, starting from the results of laboratory tests. The behavior of the Battery internal temperature has been characterized. Then, the designed model has been used to evaluate the economic profitability in installing a storage system in the case that end-users are already equipped with a photovoltaic unit. To obtain realistic results, real field measurements of customer consumption and solar radiation have been considered. A concrete interest in adopting the sodiumnickel Chloride technology at the residential level is confirmed, taking into account the achievable benefits in terms of economic income, back-up supply, and increased indifference to the evolution of the electricity market.

  • easy approach to realize low cost and high cell capacity in sodium nickel iron Chloride Battery
    Composites Part B-engineering, 2019
    Co-Authors: Byungdong Hahn, Jongjin Choi, Keeyoung Jung, Yooncheol Park, Joonhwan Choi
    Abstract:

    Abstract A sodium metal Chloride Battery is one of the promising candidates in the Battery energy storage system which has gained considerable attention due to the global interest about environment. An easy approach is shown, in this study, to obtain the low cost and high cell capacity in a Na-(Ni,Fe)Cl2 Battery. It is the usage of Fe particles which are larger than Ni particles. Consequently, the Ni content is significantly decreased to be approximately 50 wt % in the Na-(Ni,Fe)Cl2 cell, and this cell shows an excellent cell capacity of 263 mAh g−1 (per the weight of Ni-Fe composites). In general, the Ni content is 86–100 wt % in a Na-(Ni,Fe)Cl2 [or Na-NiCl2] Battery. Especially, in this manuscript, a simple test cell is also suggested for the study of active materials in a Na-MCl2 (M: metal) Battery. Until now, it has been difficult to study a sodium metal Chloride Battery in a small-and-academic laboratory, since a lot of exclusive equipment is necessary to assemble the cell. It is expected that this simple test cell can assist the study of a sodium metal Chloride Battery in an academic laboratory.

  • microstructure design of metal composite for active material in sodium nickel iron Chloride Battery
    Journal of Power Sources, 2016
    Co-Authors: Byungdong Hahn, Keeyoung Jung, Yooncheol Park, Inchul Hong, Goyoung Moon, Joonhwan Choi
    Abstract:

    Abstract In this manuscript, it is reported how the microstructure of metal composites can be designed to obtain excellent cycle performance in Na-(Ni,Fe)Cl 2 Battery. The microstructure consists of an active material and a conducting material. The conducting material is an active material as well as a conducting chain (an electron path). In Na-(Ni,Fe)Cl 2 cells, it is preferable that Ni is selected as the conducting material, since the nickel Chloride is not formed on the surface of Ni particles during the electrochemical reaction of Fe particles. In addition, the particle size of Ni should be smaller than that of Fe, in order to ensure that the conducting chain is well-connected. Through this design, the cycle performance of a Na-(Ni,Fe)Cl 2 cell was significantly improved, compared to that of a Na-NiCl 2 cell. At the 100th cycle, the charge/discharge capacity of a Na-(Ni,Fe)Cl 2 cell was much higher than that of a Na-NiCl 2 cell, approximately 42%.

  • Influence of Carbon Coating on Beta-Alumina Membrane for Sodium–Nickel Chloride Battery
    Bulletin of The Korean Chemical Society, 2015
    Co-Authors: Keeyoung Jung, Yooncheol Park, Joonhwan Choi
    Abstract:

    Sodium–nickel Chloride batteries have been used as energy storage devices because of their high operating voltage, ease of assembly in a discharged state, the less corrosive nature of the cathode materials, safer cell failure mode, and better tolerance against overcharging. In this study, we fabricated a planar-type cell equipped with an elastic spring rod in the anode to maintain effective sodium utilization. In addition, we investigated the influence of carbon coating on the β″-Al2O3 membrane. The carbon coating layer on the β″-Al2O3 membrane showed improved wettability for sodium metal. The carbon-coated alumina membrane delivered a higher initial charge/discharge capacity than the pristine membrane cells.
