“Researchers…have fabricated hybrid coaxial metal-oxide/carbon nanotube arrays as cathode material for high performance lithium-ion batteries. The coax tubes consist of a manganese oxide (MnO2) shell and a highly conductive nanotube (CNT) core…The team…found that stronger cyclic stability and capacity of MnO2/CNT coaxial nanotube electrodes resulted from the hybrid nature of the electrodes with improved electronic conductivity and a dual mechanism of lithium storage. The reversible capacity of the battery was increased by an order compared to template grown MnO2 nanotubes, making them suitable electrodes for advanced Li-ion batteries…” Full Slice
