“…To precipitate Li 2 CO 3 , the catholyte was heated at 75 °C for 2 h. As a result, the heating step consumed 17 kW h/g Li, which was over 98% of the total energy provided. Various heating sources have been reported, including energy from nuclear reactors, radiant panels, and other renewable and green sources that have been studied and applied to practical use for decades. − By introducing these heating methods, the process will be much lower in energy consumption and more promising for commercial adoption.…”

Recycling of lithium-ion batteries (LIB) has focused on the recovery of metals such as Co and Ni due to their intrinsic values. Among these metals, recycling of Li requires hydrometallurgical routes that are not widely implemented due to the higher costs associated with energy and chemical consumptions. This makes Li recovery from recycling less economical than obtention from mineral ores. In the present study, Li as well as Mn were recovered through electrodialysis (ED) from the leachates of spent LIBs by employing a CO 2 -capture agent N-methyldiethanolamine as a regenerable catholyte. Surrogate solutions and Li-rich leachates were tested for the separation and recovery of Li and Mn as Li 2 CO 3 and MnCO 3 , respectively. The purity of recovered Li 2 CO 3 99.6% achieved battery-grade purity levels from both surrogate and leachate solutions. It was observed that MnO 2 was deposited on the Pt anode only from the surrogate solutions. Energy consumption of the ED was low at 0.5 kW h/g Li. The overall process recovered high-purity Li from LIB leachate, with CO 2 being the only chemical consumed. This process is presented as an environment-friendly and energy-effective method in Li 2 CO 3 recovery from LIB materials.

“…The thermally activated building system (TABs) is one of the most efficient distribution systems that can be improve indoor climate with lower air speeds based on different energy sources [10,11], it consists of heat exchangers which meet the heating/cooling demands of the buildings by conducts heat to/from the thermal mass of building in form of radiation, which mean that the TABs reduces the dispersion of aerosol particles and gaseous pollutants to the minimum in the indoor environments [12].…”

Motivated by the rapid spread of the novel pandemic disease (COVID-19) that swept the most countries in the world, a new radiation heating system consists of wall radiator panel system connected to a reversible geothermal heat pump (GHP) coupled with horizontal ground heat exchanger (HGHX) was proposed as fast and permanent solution to the risks of the dispersion of airborne infectious diseases in air-conditioned enclosed spaces. An experimental system was installed and tested in the laboratory of thermal process of Research and Technology Center of Energy (CRTEn), Tunisia, in order to achieve the two main goals of this work: developing a new radiation heating system with quick and inexpensive implementation while ensuring high efficiency and environment-friendly performance for the entire system. The results obtained show that it is feasible to use the novel RPHs as heat rejecter of the horizontal ground source heat pump system (HGSHPs) for heating buildings with limited surface land areas epically those located in the Mediterranean regions such as Tunisia, the average performance coefficients of the geothermal heat pump COPhp and the overall system COPsys are found to be 6.3 and 3, respectively. The thermal comfort analysis indicates that there is only a small vertical temperature fluctuation in the test room that would not produce any negative effect on thermal comfort.

“…By operating the program EnergyPlus, Bojic et al [6] noted that the newly developed floor and ceiling radiant heating system had the most efficient performance, whereas, the conventional ceiling heating had the worst performance. On the other hand, it was estimated that in the upcoming days, with the decrease of primary energy consumption coefficient (R) the panel heating using ground source heat pump as heating source might have less total energy consumption than a system consuming natural gas.…”

In the present study, a computational investigation is carried out within a model room of which dimensions has also been given in international standards for experimental approaches. In accordance with the experimental standards, the analyses are realized at the room dimensions of (L x H x W= 4 x 3 x 4 m), and at the thermal boundary conditions of (Tc= 35-50 o C), (Tw= 15-24 o C), (Tf= 15-24 o C). As a result of iterations conducted using a computational fluid dynamics package program code, each corresponding to a case study, convective, radiative, and total heat fluxes from radiant heated ceiling are obtained, and afterward using relevant reference temperature proposed in the literature, heat transfer coefficients pertaining to convection, radiation, and total heat transfer have been found. In conclusion, average heat flux values of 95.83 Wm-2 and 17.49 Wm-2 are gained through the examined radiant heated ceiling, by means of radiation and convection, respectively. This denotes that roughly 85% of total heat transfer from the ceiling arises through radiation that is very compatible with the relevant literature. Finally, spanning the entire different case studies, average convective, radiative, and total heat transfer coefficients of 1.
