As potential substitutes, development of organic-based aqueous RFBs is impeded by a lack of electroactive pairs with combination of high cell voltage and sufficient cycle stability. In this work, a novel biomolecule-based aqueous RFB with high performance was successfully fabricated. Lawsone, a renewable biomolecule derived from natural henna, was developed as a stable anolyte. By paring with 4-HO-TEMPO, the as-assembled RFB exhibits a high operating voltage above 1.30 V, which is among the highest records. Meanwhile, the capacity retention rate reaches 99.992\% per cycle.

Additionally, efforts to develop sustainable manufacturing of lithium ion batteries are still lacking, with no prevailing strategy developed yet to handle recyclability of ASSBs. To date, most SSE research has been largely focused on the discovery of novel electrolytes. Recent review articles have extensively examined a broad spectrum of these SSEs using evaluation factors such as conductivity and chemical stability. Recognizing this, in this Review we seek to evaluate SSEs beyond conventional factors and offer a perspective on various bulk, interface and nanoscale phenomena that require urgent attention within the scientific community. We provide a realistic assessment of the current state-of-the-art characterization techniques and evaluate future full cell ASSB prototyping strategies. We hope to offer rational solutions to overcome some major fundamental obstacles faced by the ASSB community, as well as potential strategies toward a sustainable ASSB recycling model.}, - author = {Darren H.

As batteries have transitioned from being used in portable electronics to being used in longer lifetime and more safety-critical applications, such as electric vehicles (EVs) and aircraft, the cost of failure has become more significant both in terms of liability as well as the cost of replacement. Failure modes, mechanisms, and effects analysis (FMMEA) provides a rigorous framework to define the ways in which lithium-ion batteries can fail, how failures can be detected, what processes cause the failures, and how to model failures for failure prediction. This enables a physics-of-failure (PoF) approach to battery life prediction that takes into account life cycle conditions, multiple failure mechanisms, and their effects on battery health and safety. This paper presents an FMMEA of battery failure and describes how this process enables improved battery failure mitigation control strategies.}, - author = {Christopher Hendricks and Nick Williard and Sony Mathew and Michael Pecht}, - doi = {10.1016/j.jpowsour.2015.07.100}, - issn = {0378-7753}, - journal = {Journal of Power Sources}, - keywords = {Lithium-ion battery, Failure modes, mechanisms, and effects analysis, Physics-of-failure, Battery reliability}, - pages = {113–120}, - title = {A failure modes, mechanisms, and effects analysis (FMMEA) of lithium-ion batteries}, - url = {http://www.sciencedirect.com/science/article/pii/S0378775315301233}, - urldate = {2020-12-27}, - volume = {297}, - year = {2015} -} - -@misc{batt-uni-bms, - author = {{Battery University}}, - howpublished = {Online}, - month = mar, - title = {Battery Management System (BMS)}, - url = {https://batteryuniversity.com/index.php/learn/article/how_to_measure_state_of_charge}, - urldate = {2020-12-27}, - year = {2017} -} - -@misc{tophat-tms, - author = {SMD}, - howpublished = {Online}, - month = dec, - title = {Work Class ROVs}, - url = {https://www.smd.co.uk/wp-content/uploads/2016/12/SMD_2685_ROV_Brochure_pps_low_res.pdf}, - urldate = {2020-12-28}, - year = {2016} -} - -@misc{splash-zone, - author = {{Mark Tool \& Rubber}}, - howpublished = {Online}, - month = dec, - title = {What is the Splash Zone and How to Protect It?}, - url = {https://www.marktool.com/what-is-the-splash-zone-and-how-to-protect-it}, - urldate = {2020-12-28}, - year = {2012} -} - -@misc{rov-tms-splash-zone, - author = {Claudio Paschoa}, - howpublished = {Online}, - month = jan, - organization = {Marine Technology News}, - title = {Understanding ROV Launch and Recovery Systems – Part 2}, - url = {https://www.marinetechnologynews.com/blogs/understanding-rov-launch-and-recovery-systems-e28093-part-2-700532}, - urldate = {2020-12-28}, - year = {2015} -} - -@misc{18650-ecolux, - author = {Ecolux}, - howpublished = {Online}, - title = {18650 Batteries}, - url = {https://www.ecoluxshopdirect.co.uk/by-size/18650-batteries}, - urldate = {2020-12-28}, - year = {2020} -} - -@misc{18650.uk, - author = {18650.uk}, - title = {18650 Batteries}, - url = {https://18650.uk/shop/18650-batteries}, - urldate = {2020-12-28}, - year = {2020} -} - -@misc{18350-fogstar, - author = {{Fogstar Batteries}}, - date = {2020}, - title = {18650 Batteries}, - url = {https://www.fogstar.co.uk/collections/batteries/size_18650}, - urldate = {2020-12-28} -} - -@misc{hugin-lars-article, - author = {{Offshore Engineer}}, - howpublished = {Online}, - month = mar, - organization = {Offshore Engineer Digital}, - title = {Kongsberg Develops New LARS for HUGIN AUVs}, - url = {https://www.oedigital.com/news/477126-kongsberg-develops-new-lars-for-hugin-auvs}, - urldate = {2020-12-29}, - year = {2020} -} - -@article{bms-cost-article, - author = {Celine Cluzel and Shane Slater and George Paterson and Rebecca Trengove}, - journaltitle = {Resource Guide of Battery Power}, - title = {Cost and Performance of Electric Vehicle Batteries}, - url = {https://www.batterypoweronline.com/markets/batteries/cost-and-performance-of-electric-vehicle-batteries}, - urldate = {2020-12-29}, - volume = {2012}, - year = {2012} -} - -@article{bms-cost-report, - author = {Celine Cluzel and Craig Douglas}, - journaltitle = {The Committee on Climate Change}, - month = mar, - title = {Cost and performance of EV batteries}, - url = {http://www.element-energy.co.uk/wordpress/wp-content/uploads/2012/06/CCC-battery-cost_-Element-Energy-report_March2012_Finalbis.pdf}, - urldate = {2020-12-29}, - year = {2012} -} - -@misc{batt-uni-lithium-chemistry, - author = {{Battery University}}, - howpublished = {Online}, - month = mar, - title = {Types of Lithium-ion}, - url = {https://batteryuniversity.com/learn/article/types_of_lithium_ion}, - urldate = {2020-12-29}, - year = {2017} -} - -@article{li-direct-recycling, - abstract = {Direct recycling of lithium-ion is a promising method for manufacturing sustainability. It is more efficient than classical methods because it recovers the functional cathode particle without decomposition into substituent elements or dissolution and precipitation of the whole particle. This case study of cathode-healing™ applied to a battery recall demonstrates an industrial model for recycling of lithium-ion, be it consumer electronic or electric vehicle (EV) batteries. The comprehensive process includes extraction of electrolyte with carbon dioxide, industrial shredding, electrode harvesting, froth flotation, cathode-healing™ and finally, building new cells with recycled cathode and anode. The final products demonstrated useful capability in the first full cells made from direct recycled cathodes and anodes from an industrial source.
