How can cobalt be reduced in EV batteries?
The electrification of transport is increasing. This means, more batteries are needed. However, some of these batteries contain an extremely problematic raw material: cobalt. PSI is researching alternatives.
Quartz powder for the battery of the future
PSI materials researchers have developed a method that provides crucial insights into the charging and discharging processes of lithium-sulphur batteries. And the method revealed: with quartz powder added to the battery, its available energy increases and the gradual loss of capacity is much weaker.
