“… 26 A weak peak of C (001) appears for the case of GO:Fe 2 O 3 composite with a possible overlap of C (002) and Fe (012) which signifies the formation of the nanocomposite. 27 The shift in the C (001) peak (13.2° → 13.4°) with the corresponding shift in the C (002) peak positions 23.0° → 24.3° can be attributed to inter-planar spacing originating from the quantity of absorbed water molecules in the carbon matrix. 28 The shift in peak position is consistent with the shift in the D -spacing indicated in Table 1 .…”

“…[4] Among them, iron oxides such as Fe 2 O 3 , Fe 3 O 4 , and FeO, are particularly attractive as anodes due to iron being the most abundant transition metal observed in the earth's crust. [5] The lithiation process of iron-base oxides is characterized by the reaction of Fe x O y + 2yLi + + 2ye − → xFe + yLi 2 O, with a high lithiation potential of 1.0-1.5 V vs. Li/Li + . [6] However, high lithiation potential anodes in the assembly of full batteries often result in a low output voltage, which fails to meet the high energy/power density requirements for LIBs.…”

To obtain anode materials with high capacity/energy density for lithium‐ion batteries, a polyanionic compound Li2FeGeO4 is prepared, which combines the conversion‐type Fe‐based oxide and the alloy‐type Ge‐based oxide at the atomic scale. The influence of citric acid in the sol–gel process on the structure and performance of the calcined products (LFG0, LFG1, and LFG2) is investigated. The results demonstrate that citric acid does not affect the phase of Li2FeGeO4. However, with the increase of citric acid, the crystallinity and grain size of the final product are reduced and its dispersion becomes better. Among the as‐prepared samples, LFG1 exhibits moderate particle size and more uniform dispersion, providing a high discharge capacity of 669.7 mAh g−1 at 0.5 A g−1 after 200 cycles. Based on the ex situ XPS and operando XRD tests, it is found that the electrochemical reaction process of LFG1 is controlled by both the conversion of iron/germanium and the alloying of germanium. In addition, it is verified that the reaction mechanism of LFG1 for aqueous lithium‐ion capacitors is also controlled by iron and germanium elements. Importantly, Li2FeGeO4 is first proved to be a novel anode for lithium‐ion batteries and lithium‐ion capacitors.
