In a groundbreaking review published in ‘InfoMat’, researchers are shedding light on the potential of all-solid-state batteries (ASSBs) to revolutionize energy storage, particularly within the construction sector. Rainer Götz, a lead author from the Physics Department at the Technical University of Munich, emphasizes the transformative impact of these batteries on energy density and safety. “The concept of all-solid-state batteries opens up new avenues for energy storage that could significantly enhance the efficiency of construction machinery and tools,” Götz states.
The review meticulously examines various components of ASSBs, focusing on commercially available electrolytes and their impact on overall battery performance. Götz and his team highlight that while conventional lithium-ion batteries have reached energy densities of around 250 Wh kg−1, the integration of composite cathodes with high mass loadings and optimized separator thicknesses can push ASSBs beyond 350 Wh kg−1. This leap in energy density not only promises longer-lasting power sources but also aligns with the industry’s growing demand for sustainable and efficient energy solutions.
One of the standout findings of this research is the potential for using lithium metal and anode-free approaches in ASSBs. These innovations could lead to lighter, more compact batteries that are crucial for portable construction tools and equipment. The ability to utilize readily available materials for the electrolytes also raises the prospect of cost-effective production, addressing one of the key barriers to widespread adoption.
Götz points out that, “By focusing on materials that are commercially viable, we are paving the way for practical applications of all-solid-state batteries in various sectors, including construction.” The implications of this research could extend beyond just energy storage; it may also influence how construction projects are designed, enabling new methods that rely on advanced battery technologies for powering equipment on-site.
As the construction industry increasingly turns towards sustainable practices, the development of ASSBs could play a pivotal role in reducing carbon footprints and enhancing operational efficiency. Götz’s research indicates that while current oxide electrolytes may not yet outperform existing lithium-ion solutions, the ongoing optimization of battery components signals a promising future for ASSBs.
With the construction sector poised for transformation through innovative energy solutions, the insights provided by Götz and his colleagues could very well be the catalyst for a new era of energy-efficient construction practices.
