However, the high entropy and high enthalpy features make SSEs only stable at relevant high temperatures. When the temperature drops, a phase transition or decomposition would happen, resulting in much lower ionic conductivity. This limits the development and diversity of SSEs. Additionally, the decrease in ionic conductivity caused by phase transition also significantly affects the electrochemical performance of all solid-state batteries at low temperatures. Therefore, the study and regulation of phase transitions in SSEs are of great significance for the development of new SSEs and the improvement of the electrochemical performance of ASSBs at low temperatures. In this review, we mainly summarize the phase transitions in superionic conductors, techniques to determine such transitions, and methods to stabilize those metastable phases at room temperature. Additionally, we will give a possible experimental approach to new superionic conductors.</p></div>","PeriodicalId":11028,"journal":{"name":"Current Opinion in Electrochemistry","volume":"46 ","pages":"Article 101537"},"PeriodicalIF":8.5,"publicationDate":"2024-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141136518","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Research in this area is improving photocurrent outputs through genetic engineering, the addition of redox- and conductive-polymers, the use of diffusional redox mediators, electrode design, and expanding the selection of microorganisms used to generate photocurrents. This review covers the most promising research from the last two years that has sought to understand the mechanisms of photocurrent generation and increase the magnitude of photocurrent outputs.

In this regard, the microbial fuel cell (MFC) technology has shown much promise as a revolutionary wastewater treatment + energy generation hybrid.

This article critically assesses the current development of MFC technology, particularly in the last two years, focussing on the technology's economic and environmental feasibility. Even though there is a significant body of literature on MFCs with continuously increasing performance levels, the technology has not yet got fully commercialised to form part of urban planning or energy policy; this implies a lack of government consideration as a result of the absence of industrial scale research. The article presents the case for MFCs from a technology readiness level and life cycle assessment perspectives and explains why it is still premature to draw conclusions based on these two metrics.</p></div>","PeriodicalId":11028,"journal":{"name":"Current Opinion in Electrochemistry","volume":"46 ","pages":"Article 101540"},"PeriodicalIF":8.5,"publicationDate":"2024-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2451910324001017/pdfft?md5=9eb97334896203f6006d34f31cfd8f43&pid=1-s2.0-S2451910324001017-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141143362","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
