Lithium metal borate (LiMBO3) family of insertion materials for Li-ion batteries: a sneak peak

Abstract

Rechargeable lithium-ion battery remains the leading electrochemical energy-storage device, albeit demanding steady effort of design and development of superior cathode materials. Polyanionic framework compounds are widely explored in search for such cathode contenders. Here, lithium metal borate (LiM-BO 3 ) forms a unique class of insertion materials having the lowest weight polyanion (i.e., BO 3 3− ), thus offering the highest possible theoretical capacity (ca. 220 mAh/ g). Since the first report in 2001, LiMBO 3 has rather slow progress in comparison to other polyanionic cathode systems based on PO 4 , SO 4 , and SiO 4 . The current review gives a sneak peak to the progress on LiMBO 3 cathode systems in the last 15 years highlighting their salient features and impediments in cathode implementation. The synthesis and structural aspects of borate family are described along with the critical analysis of the electrochemical performance of borate family of insertion materials.

A bio-facilitated synthetic route for nano-structured complex electrode materials

“…The developed procedure can keep the relatively long time of ball-milling and firing processes that are conventionally used for LiMnBO 3 synthesis. [16][17][18] We optimize the specific M13 virus with the p8 insert sequence of DSPHTELP not only to mineralize the seed material but also to bind SWCNTs onto the material. DSPHTELP has a histidine (H), an aromatic residue that could interact with SWCNTs through π-π stacking at all pH ranges.…”

“…In this work, we apply this technique to synthesize a Li storage nanomaterial, monoclinic lithium manganese borate (LiMnBO 3 ), which has been obtained mostly by conventional methods to date. [16][17][18] This borate composition shows polymorphism in hexagonal and monoclinic structures and has a high theoretical capacity of 220 mA h g −1 with good phase stability. 18,19 However, both polymorphs show limited capacities in battery tests, likely originating from sluggish Li mobility due to the nature of one-dimensional diffusion.…”

Effects of Ti Doping on the Structural Stability and Enhanced Electrochemical Performance of α‐LiVOPO4

“…Polyanion materials such as phosphates, silicates, fluorosulfates, and borate are expected to have large‐scale applications as cathode materials because of their safety and energy density. Phosphate‐based materials provide thermal stability and can be used as a high voltage electrode material due to the inductive effects of the PO 4 unit.…”

Unusual stoichiometry control in the atomic layer deposition of manganese borate films from manganese bis(tris(pyrazolyl)borate) and ozone

“…[1][2][3][4] Recently, first row transition metal borates have emerged as dioxygen (O 2 ) evolution catalysts, [5][6][7][8][9][10][11][12][13][14][15][16] cathode materials in lithium ion batteries, [17][18][19][20][21][22] catalysts for H 2 production by hydrolysis of sodium borohydride, 23 and superhydrophilic Ni 3 (BO 3 ) 2 layers. 24 For many applications, metal borates must be grown as thin films.…”

“…34 ALD growth from various bimetallic precursors does not generally replicate the precursor element stoichiometries in the resultant thin films. [35][36][37][38] Given the increasing importance of first row transition metal borates, [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24] proposed to arise from the strong oxidizing properties of higher valent manganese oxide layers that are formed upon ozonolysis of surface manganese sites.…”
