“…Over the past few decades, the structure of borates has been widely investigated. Previous studies report that the basic structures of borate are [BO 3 ] 3– triangle planar and [BO 4 ] 4– tetrahedron and these B–O anions are connected by the same atom or edge to form different complicated polyanion clusters. , Meanwhile, these B–O anions and polyanion clusters can combine with metal ions, including Al, Fe, Sc, and In, to form Metal–O–B structures. − On the basis of these findings, we infer that the Fe derivatives from the mild steel pipeline can react with B–O anions to form a passive film on the pipeline surface and suppress corrosion.…”

On the basis of their potential passivating characteristics, in this study, borates have been used to synthesize a novel slow-release inhibitor to suppress long-term mild steel corrosion in simulated recirculating water. The passivating performance was characterized by various electrochemical measurements and the passivating mechanism was interpreted by the point defect model. The experimental results indicated that the slow-release inhibitor exhibited a passivating efficiency of over 98% after 30 days of immersion, due to the formation of a passive film that was predominant by a Fe-O-B structure on the mild steel surface. This study provides a novel controlled-release concept and a slow-release borate inhibitor to control long-term corrosion.

“…Finally, a few studies have been devoted to the reactivity of borates such as MBO 3 (M = V and Fe [283][284][285] ), M 3 BO 6 (M = Fe [ 283 , 286 ] and Cr [ 287 ] ), and M 3 B 2 O 6 (M = Co, Ni, and Cu) [ 288 ] as negative electrodes. Although the initial discharge capacities are close to 1000 mAh g − 1 , their response upon cycling is rather poor, with the best values (350 mAh g − 1 after 35 cycles) being reported for Fe 3 BO 6 .…”

Beyond Intercalation‐Based Li‐Ion Batteries: The State of the Art and Challenges of Electrode Materials Reacting Through Conversion Reactions

et al. 2010

Despite the imminent commercial introduction of Li-ion batteries in electric drive vehicles and their proposed use as enablers of smart grids based on renewable energy technologies, an intensive quest for new electrode materials that bring about improvements in energy density, cycle life, cost, and safety is still underway. This Progress Report highlights the recent developments and the future prospects of the use of phases that react through conversion reactions as both positive and negative electrode materials in Li-ion batteries. By moving beyond classical intercalation reactions, a variety of low cost compounds with gravimetric specific capacities that are two-to-five times larger than those attained with currently used materials, such as graphite and LiCoO(2), can be achieved. Nonetheless, several factors currently handicap the applicability of electrode materials entailing conversion reactions. These factors, together with the scientific breakthroughs that are necessary to fully assess the practicality of this concept, are reviewed in this report.

“…Then, its high electronegativity as well as its ability to be either three- or four-oxygen coordinated offer a great variety of redox potentials for the adjunct cation. Because of environmental (no toxicity) and economic (material cost) factors, only iron borates have been widely studied versus lithium up to now. − However, such studies were complicated by the difficulties encountered in synthesizing a single-phase material, and in characterizing the amorphous phases obtained during cycling, despite Mössbauer spectroscopy studies . Nevertheless, their electrochemical properties versus Li present several features similar to those obtained by our group with metal oxides, namely low potential reactivity, extra capacity, and important polarization.…”

Study of the Reactivity Mechanism of M₃B₂O₆ (with M = Co, Ni, and Cu) toward Lithium

The electrochemical reactivity mechanism of M 3 B 2 O 6 (with M ) Co, Ni, and Cu) powders toward lithium was studied by a combination of transmission electron microscopy (TEM), infrared spectroscopy (IR), 11 B magic angle spinning nuclear magnetic resonance (MAS NMR), and electrochemical techniques. The electrochemical properties of these materials as anodes for lithium batteries were investigated and found to be similar to those of 3d-metal oxides. In fact, the reduction process of 3d-metal borates involves their decomposition in metal nanograins dispersed into a lithia matrix surrounded by an organic layer responsible for the observed extra capacity. The lithia matrix consists of a mixture of lithium oxide (Li 2 O) and lithium orthoborate (Li 3 BO 3 ). During the subsequent charge, the organic layer vanishes and the metal grains are partially or fully oxidized with the concomitant decomposition of Li 2 O. The formation of Li 2 O and metal nanograins during the discharge, as well as that of oxides nanograins during the following charge, were identified by HRTEM studies while Li 3 BO 3 was detected by IR spectroscopy and 11 B MAS NMR techniques.
