Researchers at the University of Tokyo have unveiled a breakthrough cobalt-free lithium-ion battery prototype that has the potential to revolutionize the electric vehicle industry. Traditional lithium-ion batteries often contain controversial cobalt, but this innovation uses a cobalt-free alternative, combining electrodes of lithium, nickel, manganese, silicon and oxygen to improve battery performance. By introducing innovative electrolytes, the battery can maintain 80% of its storage capacity after 1,000 charge and discharge cycles, overcoming the problem of battery damage during long-term use. This technology is not only environmentally friendly, but also has 60% higher energy density than lithium iron phosphate batteries, extending the battery life of electric vehicles, smartphones and other devices. The University of Tokyo plans to collaborate with commercial companies, including licensing the technology. This development is in line with the global trend towards cleaner, sustainable energy solutions.
