Scientists reveal the hidden costs of cobalt mining in DR Congo

In recent years, the demand for cobalt, a crucial component of rechargeable lithium-ion batteries for smartphones and electric cars, has been on the increase. Around 60 percent of the world's cobalt supply comes from the ...

Optimizing lithium-sulfur battery electrolytes for long life

In the future, lithium-sulfur (Li-S) rechargeable batteries could hold more energy and cost less than lithium-ion batteries if they can be made to last longer. A key challenge is preventing the polysulfide ions that must ...

Silicon as a new storage material for the batteries of the future

Longer life times, larger ranges and faster recharging—developments such as electric mobility or the miniaturisation of electronics require new storage materials for batteries. With its enormous storage capacity, silicon ...

Catching radical molecules before they disappear

While in most molecules, each electron finds a partner to pair up with, some electrons in radical molecules are left alone and unpaired. This configuration grants radicals with some unusual and interesting properties, which ...

A gel that does not break or dry out

Researchers have developed a highly robust gel that includes large amounts of ionic liquid. The research team was led by Professor MATSUYAMA Hideto and Assistant Professor KAMIO Eiji (Kobe University Graduate School of Science, ...
