Lithium–Lanthanide Bimetallic Metal–Organic Frameworks towards Negative Electrode Materials for Lithium‐Ion Batteries

Abstract

Novel lithium-lanthanide (Ln:c erium and praseodymium) bimetallic coordination polymers with formulas C 10 H 2 LnLiO 8 (Ln:C e( CeLipma) and Pr (PrLipma)) and C 10 H 3 CeO 8 (Cepma) were prepared through as imple hydrothermal method.T he three compounds were characterized by means of FTIR spectroscopy,X -ray diffraction, single-crystal X-ray diffraction, SEM, TEM, and X-ray photoelectron spectroscopy.T he results of structuralr efinement show that they belong to triclinic symmetry and P1 space group with cerium (or praseodymium) and lithiumc ations, forming co-ordination bonds to oxygen atoms from different pyromellitic acid molecules, and leading to the constructiono f3 D structures.I ti si nterestingt on ote that the frameworks exclude any coordination water and lattice water.A sa ne lectrode material for lithium-ionb atteries, CeLipma exhibits a maximumc apacity of 800.5 mAh g À1 and ar etention of 91.4 %a fter 50 cycles at ac urrent density of 100 mA g À1 .T he favorable electrochemical properties of the lanthanide coordination polymers show potential application prospects in the field of electrode materials.

Metal‐organic frameworks and their derivatives as anode material in lithium‐ion batteries: Recent advances towards novel configurations

“…For instance, novel lithium-cerium BMOFs were synthesized and tested for their electrochemical performance. 30 This lithium-cerium BMOF has shown an initial charge capacity of 150.2 mAhg À1 at current density of 100 mAg À1 which is quite low as SEI layer is formed. However, the charge capacity increased rapidly to 800.5 mAhg À1 after several cycles to retain 91.4% of capacity even after 50 cycles.…”

“…Also, MOFs are advantageous in terms of tuneable redox properties, desirable structural changes, cost effectiveness, and simple synthetic mechanism. Some standard reports have robustly illustrated the promising electrochemical performance of MOF‐based negative electrodes in LIBs 30 …”

“…These types of MOFs are called bimetallic metal‐organic frameworks (BMOF). For instance, novel lithium‐cerium BMOFs were synthesized and tested for their electrochemical performance 30 . This lithium‐cerium BMOF has shown an initial charge capacity of 150.2 mAhg −1 at current density of 100 mAg −1 which is quite low as SEI layer is formed.…”

A Review of Cobalt-Containing Nanomaterials, Carbon Nanomaterials and Their Composites in Preparation Methods and Application

“…Currently, LIBs anode materials include the following categories: alloys [23,24], carbonbased materials [25,26], metal oxides [27,28], metal sulfides [29,30], and metal organic frameworks (MOFs) [31,32]. In addition, Manickam Minakshi et al used binary transition metal oxides, phosphates, and molybdenum salts as anodes for LIBs and sodium-ion batteries (SIB) and achieved good experimental results [33][34][35].The anode materials first explored for LIBs conversion reaction are first-row transition metal oxides (TMOs), such as Fe 2 O 3 , MnO 2 , NiO, and Co 3 O 4 [36,37], of which Co 3 O 4 has the best performance [12].…”

Hydrophobic POM Electrocatalyst Achieves Low Voltage “Charge” in Zn‐Air Battery Coupled with Bisphenol A Degradation

“…Greenhouse and noxious gases emitted by fossil fuel dependent cars have triggered frightening climate variation, severe environmental changes, and an energy crises [1] . Electric vehicles are desired succedaneum for above traditional cars due to their poor CO 2 and poisonous NO, CO, SO 2 emission [2] . For electric vehicles, the absence of high performance and environment‐friendly battery becomes a main obstacle [3] .…”
