Title : Global developments and breakthroughs in solid state metal-air EV battery technologies
Abstract:
In achieving the target of NetZero emissions by 2050 it is expected that EV batteries play a significant role. Global warming and the rapid development global EV fleet are resulting faster development of renewable energy solutions focusing on alternatives to Lithium ion batteries (LIBs) because of various limitations though LIBs are the most extensively used among the current battery systems. In this connection metal -air batteries (MABs) and rechargeable solid state metal-air batteries (SSMABs) are attracting attention among the alternatives to LIBs because of several favourable factors including high energy density, safety, low cost, sustainability, eco-friendly and others. There are several inherent challenges in MABS and SSMABs to be solved before mass production. Among the SSMABS Lithium- air solid state batteries (SSLABs) are most widely studied because of the highest energy density among all batteries in view of variety of possible energy applications including EVs, electric aircrafts and heavy trucks. In this presentation initially an over view of MABs and SSMABS is presented highlighting the advantages and current challenges to be overcome before commercialisation of SSMABs for several energy applications. The developments and breakthroughs in SSMABs are presented with a focus on developments in SSLABs including developments of start up Air Energy for commercialisation of SSLABs in the next five years by Prof. Asadii group. The details about the breakthrough in all Solid State Magnesium- air rechargeable batteries using metal -free Nano porous Grapheme is also discussed. The breakthrough in Nano scale silver coating which solved major problem in solid state batteries has also presented. The developments in other SSMABs including Solid State Zinc –air and solid state sodium- air batteries have also been reviewed. The timelines for the commercial availability of SSMABs and SSLABs have been indicated. The forecast of market trend with respect to SSMABs and expectations on the cost of SSLABs have also been presented. Finally, future focus areas of research for large scale production of SSMABs has also been given.
