“…The overlapping of diffraction peaks also exists in other Co‐based structures . After solvothermal treatment of the precursors, ultra‐long microrods are formed with a new dominant crystal phase of monoclinic CoC 2 O 4 ⋅ 2H 2 O (JCPDS 25‐0251, monoclinic, C2/c ) (Figure d, green) . The strong diffraction peaks indicate that the microrods have high crystallinity, which is consistent with the SEM images.…”

Herein, we propose the concept of hierarchical-dimensional materials (HDMs), which are 3D superstructures built by lowdimensional single-crystalline substructures. HDMs combine the low-and high-dimensional features and are a new class of promising functional materials toward electrochemical reactions. We reported a hierarchical-dimensional cobalt hydroxide nanosheet assembly for electrocatalytic water oxidation. The assembling is 1D-oriented, the substructures are 2D nanosheets, and 3D voids are created in the material. The as-prepared material achieved superior electrocatalytic activity than isolated substructures. The better performance is associated with the improved mass transport, which is demonstrated by the analysis of kinetic-controlled currents. This protocol can also be applied in preparing efficient catalysts on the surface of industrial current collectors. The proposed concept of HDMs might open a new area of functional materials in heterogeneous electrocatalysis.

“…The above-mentioned metal oxalates are produced via several synthetic methods such as spray pyrolysis, solvothermal reaction, sol–gel methods, , hydrothermal reaction, and microwave-assisted solution approaches . Nacimiento et al employed polyacrylonitrile (PAN) to improve the dispersion of SnC 2 O 4 particles. According to our prior work, the attachment of NiC 2 O 4 ·2H 2 O nanorods onto rGO sheets effectively prevented agglomeration and improved the electric conductivity, which is attributed to the intimate contact between oxalate materials and electro-conducting rGO sheets.…”

Unlike for SnO, few studies have reported on the use of SnCO as an anode material for rechargeable lithium batteries. Here, we first introduce a SnCO-reduced graphene oxide composite produced via hydrothermal reactions followed by a layer-by-layer self-assembly process. The addition of rGO increased the electric conductivity up to ∼10 S cm. As a result, the SnCO-reduced graphene oxide electrode exhibited a high charge (oxidation) capacity of ∼1166 mAh g at a current of 100 mA g (0.1 C-rate) with a good retention delivering approximately 620 mAh g at the 200th cycle. Even at a rate of 10 C (10 A g), the composite electrode was able to obtain a charge capacity of 467 mAh g. In contrast, the bare SnCO had inferior electrochemical properties relative to those of the SnCO-reduced graphene oxide composite: ∼643 mAh g at the first charge, retaining 192 mAh g at the 200th cycle and 289 mAh g at 10 C. This improvement in electrochemical properties is most likely due to the improvement in electric conductivity, which enables facile electron transfer via simultaneous conversion above 0.75 V and de/alloy reactions below 0.75 V: SnCO + 2Li + 2e → Sn + LiCO + xLi + xe → LiSn on discharge (reduction) and vice versa on charge. This was confirmed by systematic studies of ex situ X-ray diffraction, transmission electron microscopy, and time-of-flight secondary-ion mass spectroscopy.

“…This property results from the ability to provide high stability performance at low cost, alongside environmental friendliness and high theoretical capacity performance. Therefore, the product is considered a promising substitute for graphite [7], [8], while the oxalate precursor for transition metal is possibly applied as a raw material during the development of anode [9]- [11]. This specifically provides a higher capacity for both charge and discharge than the oxide forms [12].…”

Significant demand of Li-ion batteries (LIBs) is raising awareness of future LIBs wastes which are highly required to be reprocessed, reused or recycled. In this research, copper foil waste from spent LIBs are upcycled as an anode material, CuO. Hydrometallurgical route was applied to selectively dissolve copper foils where nitric acid, maleic acid and acetic acid were used as the leaching agents while oxalic acid were used to precipitate copper into copper oxalate which is a precursor to CuO. CuO was obtained by calcination of copper oxalate at high temperature. Based on XRD and FTIR analysis, Copper (II) oxalate dihydrates is successfully obtained while SEM images of the samples confirmed micron sized agglomerates which is consist of submicron primary particles. XRD analysis of CuO samples obtained from various leaching process confirmed that a pure CuO is successfully synthesized from nitric acid leaching process while CuO from acetic acid and maleic acid leaching has Cu2O and Cu phase. CuO and 10%CuO@graphite sample from nitric acid leaching were used as sole anode and composite anode in a LiNi0.8Co0.1Mn0.1O2(NCM) battery, respectively. The initial columbic efficiency of CuO anode was far inferior to CuO@graphite. However, CuO@graphite had higher specific charge-discharge capacity with the value of 347.8 mAh/g compared to pure graphite (286.5 mAh/g). In conclusion, Cu-foils are a promising source of CuO to enhance the capacity of commercial graphite anode.
