Atomic‐scale tracing of lithium trapped in copper current collectors

Article excerpt

Any loss of lithium reduces the capacity and service life of lithium batteries. Recent research suggested that lithium is lost to the current collector during charging. Researchers at Ruhr University Bochum, Germany, working with Professor Tong Li at the Helmholtz Institute Ulm and a team led by Professor Dominic Bresser at the Karlsruhe Institute of Technology, Germany, took a closer look at this hypothesis.
