A stable filamentous coaxial microelectrode for Li-ion batteries: a case of olivine LiFePO4†
Abstract
By using a facile spray drying method, we fabricated a stable filamentous coaxial microelectrode of olivine LiFePO4, which delivers an excellent electrochemical performance in Li-ion batteries. Due to its simple structure, the microelectrode is a perfect model to study electrochemical reactions, even through in situ electrochemical measurements.
