Boosting the lithium storage capability of Li <sup>+</sup> -conductor LiInGeO <sub>4</sub> through intrinsic and extrinsic conductivity optimization
Olivine-structured LiInGeO<sub>4</sub>, a Li<sup>+</sup> conductor isotypic with LiFePO<sub>4</sub> and originally intended as a solid electrolyte, is purposed as a high-capacity conversion-alloying anode. Its poor electronic conductivity is regulated by synergistic Ru doping and conformal graphene hybridization. The anode delivers 1058.8 mAh g<sup>-1</sup> after 100 cycles at 0.1 A g<sup>-1</sup> and 412.8 mAh g<sup>-1</sup> at 10 A g<sup>-1</sup>, establishing a new paradigm for fast-charging anodes derived from Li<sup>+</sup>-conductors.
