Commercial graphite anodes used in lithium-ion batteries could be viable for replacement of lithium metal as anode in Li-S batteries. However, graphite anodes are incompatible with the commonly used ether-based electrolytes in Li-S batteries due to the Li⁺ ion and solvent co-intercalation into graphite interlayers, which leads to exfoliation. Here, we report the stabilisation of graphite anode by <i>in-situ</i> formation of quasi-solid-state electrolyte (QSSE) in Li-S batteries. The QSSE is formed by the ring-opening of molecular ethers induced by metallic molybdenum disulfide sulfur cathode host to produce long-chain polymers. The resulting gel polymer matrix exhibits ionic conductivity (1.51 mS cm^-1) comparable to that of liquid electrolyte and provides sufficient redox chemistry for the sulfur cathode without co-intercalation into the graphite anode.

The current unsteady energy supply comes from the national grid and the current energy supply is not sufficient for the clinic's operating hours and requires a sustainable and steady supply. Measured data collected from the health clinic and HOMER software were used to analyze and optimize the change in overall electricity demand for the health clinic before and during the COVID-19 pandemic. The results showed that the photovoltaic/battery hybrid energy system has a lower net present cost, compared to the Photovoltaic/Generator set/ battery hybrid energy system, but higher than the standalone generator set. However, the highest amount of carbon emission associated with the standalone generator set compared to the other two hybrid energy systems disqualifies it from being a suitable contender for the source of electricity for the health clinic.

They allow the transportation of energy over great distances and are exploited in critical parts of renewable energy technologies. Even though primary metal production industries are mature and operate optimized pyrometallurgical processes, they extensively rely on cheap and abundant carbonaceous reactants (fossil fuels, coke), require high power heating units (which are also typically powered by fossil fuels) to calcine, roast, smelt and refine, and they generate many output streams with high residual energy content. Many unit operations also generate hazardous gaseous species on top of large CO&lt;sub&gt;2&lt;/sub&gt; emissions which require gas-scrubbing and capture strategies for the future. Therefore, there are still many opportunities to lower the environmental footprint of key pyrometallurgical operations. This paper explores the possibility to use greener reactants such as bio-fuels, bio-char, hydrogen and ammonia in different pyrometallurgical units. It also identifies all recycled streams that are available (such as steel and aluminum scraps, electronic waste and Li-ion batteries) as well as the technological challenges associated with their integration in primary metal processes. A complete discussion about the alternatives to carbon-based reduction is constructed around the use of hydrogen, metallo-reduction as well as inert anode electrometallurgy.

Recycling and recovery of critical elements from E-waste using a cost-effective technology are now among the top priorities in metallurgy due to the rapid depletion of their natural resources. This paper focuses on the perceptions of recovery of REE from phosphor powder from spent fluorescent lamps regarding a possible transition toward a bio-based economy. An overview of the worldwide E-waste and REE is also demonstrated to reinforce the arguments for the importance of E-waste as a secondary source of some critical metals. Based on the use of bioprocesses, we argue that the replacement of conventional steps used in E-waste recycling by bio-based technological processes can be possible. The bio-recycling of E-waste follows a typical sequence of industrial processes intensely used in classic pyro- and hydrometallurgy with the addition of bio-hydrometallurgical processes such as bioleaching and biosorption.
