Researchers at Oregon State University have shown that potassium can work with graphite in a potassium-ion battery (KIB)—a discovery that could offer a challenge and sustainable alternative to the widely-used lithium-ion battery (LIB). Even at 5C (1395 mA/g), the soft carbon retained a capacity of 140 mA/g. after 50 cycles at 2C.
