The Evolution of Battery Technology: A Sustainable Future Ahead
Battery technology has been a driving force in shaping our modern world, yet it often goes unnoticed. Its prominence in our everyday lives can be traced back to the 1970s, when the need for alternative energy sources arose following the peak of American oil production. This era saw the introduction of lithium-ion batteries, which revolutionized energy consumption and remain widely used in commercial applications today. However, the battery industry is continuously evolving, with researchers exploring alternative materials to develop safer, more cost-efficient, and sustainable energy-dense batteries.
A recent report by McKinsey & Company has shown a significant increase in global demand for batteries, with projected yearly growth of 25% by 2030. This surge in demand has prompted scientists in battery research and development (R&D) to leverage advanced technologies and collaborative efforts to address the challenges of cleaner energy solutions. From materials characterization to quality control, next-generation tools, such as electron microscopes, are providing a better foundational understanding to enhance all aspects of clean energy research.
Collaboration across sectors is seen as a crucial step towards advancing and adopting cleaner and safer energy solutions. By bringing together experts from government, academia, manufacturing, and private sectors, a collective approach to battery development can be achieved. Government initiatives focused on alternative energy solutions empower academic researchers to excel in fundamental applications and discover novel solutions for clean energy batteries. In addition, new grant programs, such as the U.S. Department of Energy’s Battery Manufacturing and Recycling Grants Program, are fostering innovation and supporting the battery supply chain.
In September 2023, Thermo Fisher Scientific hosted its first-ever Clean Energy Forum, bringing together scientists, engineers, and students from top research institutions and leading industry firms to discuss the future of clean energy and propel battery R&D and manufacturing.
In the pursuit of finding the next breakthrough in battery technology, many scientists are exploring more common and affordable materials, such as sodium, to improve battery technology. Sodium-based batteries could offer a cleaner and safer alternative to lithium-based batteries, while solid-state electrolytes batteries and lithium iron phosphate (LFP) batteries also hold potential but require overcoming technical challenges before mass production and widespread adoption.
Advanced analytical tools for battery characterization, such as electron microscopy, spectroscopy, and mass spectrometry, are providing scientists with atomic-level insights to better understand the composition and interactions inside battery cells. This level of understanding is essential for driving innovation and developing sustainable solutions.
Sustainability is a key focus in the development of clean energy batteries, not only in the base materials but also in manufacturing and recycling. By leveraging cutting-edge analytical technologies, labs can refine the recycling process to eliminate waste, improve yields, and support battery afterlife recovery, fostering a more sustainable industry.
As the demand for batteries as the primary energy source continues to grow, the urgency for higher performing and longer-lasting batteries is evident. Whether for electric vehicles or industrial equipment, the pursuit of advanced technologies to create safer and more environmentally friendly batteries is ongoing.
The future of battery solutions, and our society at large, depends on the collaboration among key groups from government to industry. It is through this collaboration that alternative materials and new battery technologies will power a healthier, cleaner, and safer world.
At the end of the article, the author Dan Shine, senior vice president and president of Analytical Instruments at Thermo Fisher Scientific, stresses the importance of collaboration and sustainable solutions in shaping the future of battery technology.
