New Manganese Materials Bolster Cathode Capacity

The most expensive component of a battery, the cathode, requires rare transition metals such as cobalt. But previous attempts to replace cobalt with inexpensive and nontoxic manganese delivered insufficient performance. Using X-ray absorption spectroscopy at the Advanced Light Source, researchers have now optimized the composition of high-energy-density, high-capacity manganese-based cathodes. More>
