Facile Synthesis of Layer Structured GeP₃/C with Stable Chemical Bonding for Enhanced Lithium-Ion Storage.

ABSTRACT: Recently, metal phosphides have been investigated as potential anode materials because of higher specific capacity compared with those of carbonaceous materials. However, the rapid capacity fade upon cycling leads to poor durability and short cycle life, which cannot meet the need of lithium-ion batteries with high energy density. Herein, we report a layer-structured GeP₃/C nanocomposite anode material with high performance prepared by a facial and large-scale ball milling method via in-situ mechanical reaction. The P-O-C bonds are formed in the composite, leading to close contact between GeP₃ and carbon. As a result, the GeP₃/C anode displays excellent lithium storage performance with a high reversible capacity up to 1109 mA h g^-1 after 130 cycl
