Non-destructive probe shows why nickel-manganese-cobalt batteries fade
For the first time, scientists have watched a lithium-ion button cell corrode in real time, charting more than 10,000 charge cycles without cracking the battery open.
The operando experiment pinpoints manganese loss as the earliest—and…
