With the growing seriousness of climate change in the 21st century, the need for renewable and clean energy technology development has become increasingly urgent. Amidst various regulations and active efforts to achieve environmental protection and a sustainable society through environmental regulations, the secondary battery industry is a leading eco-friendly energy industry. As transportation shifts from internal combustion engines to electric vehicles, research on various types of lithium-ion batteries is actively underway.
Since their commercialization in the 1990s, lithium-ion batteries have been highly successful in powering various electronic devices and electric vehicles. However, conventional lithium-ion batteries with graphite anodes have limitations in achieving high energy density due to the low theoretical capacity (~372 mAh/g) and volumetric capacity (~735 mAh/cm3) of the anode. Meeting the growing demand for lithium secondary batteries requires the development of new battery technologies beyond conventional lithium-ion batteries.
Lithium metal has a very high theoretical capacity (~3860 mAh/g), the lowest electrochemical potential (-3.04 V vs. SHE), and the lowest density (0.53 g/cm3). Due to these characteristics, lithium metal is considered the most promising material for achieving high energy and power density per unit weight and volume.
In addition, anode-less/anode-free technologies, which use lithium-free materials for the anode or apply only a small amount of lithium, are also being actively researched. Since the anode material affects the charging speed and lifespan of the battery, eliminating or reducing it has the advantage of increasing the energy density of the battery and increasing its lifespan.
This report covers the latest trends centered on lithium metal and anode-free technologies, which are considered promising anode materials for the future. It also examined the technology and development status of more than 50 lithium metal-related companies and research institutes in Korea, China, Japan, North America, and Europe. Lastly, the market analysis section predicts the demand and size of the lithium metal anode material market by 2030, taking into account the utilization in xEVs and other emerging applications within the next-generation battery market landscape.
