Tin-based anode materials have emerged as a promising candidate for lithium-ion batteries due to its inexpen-sive cost and high theoretical specific capacity, whereas its potential application is limited by severe capacity attenuation and inferior cycling stability due to the huge volume fluctuation during lithiation/delithiation. Herein, SnO2/Cu@Carbon composite was fabricated to overcome this problem through a facile co-precipitation approach followed by carbon coating. In the as-prepared composite, SnO2 and Cu particles are uniformly embedded in N-doped carbon network matrix. Such unique sa...
