However, batteries include various elements, including cobalt, contributing to environmental, economic, and social difficulties.
Even though LIB designs offer one of the most power-dense portable power sources today, requirements for higher energy-density models are arising to last longer or power more demanding devices. Apart from the ethical and sustainable production issues of cobalt, there are several reasons a move away from it is ideal for developing lithium-ion batteries. "For us, the challenge is a technical one, but its impact could be environmental, economic, social, and technological," said Professor Atsuo Yamada from the Department of Chemical System Engineering at the University in a
Yamada and his team's novel electrodes and electrolytes are not only cobalt-free, but they also improve on conventional battery chemistry in several aspects. Tests have shown that these LIBs have a 60 percent greater energy density, which might imply a longer life, and can provide 4.4 volts compared to 3.2-3.7 volts in standard LIBs.
