“…There are three pairs of reduction/oxidation peaks at 0.59/0.95, 0.75/1.84, and 1.33/2.32 V, indicating a stepwise reaction mechanism. According to previous reports, during the first discharge, the BiFeO 3 material will undergo a conversion reaction and transform to Bi and Fe metals. − Then, the Bi metals react with the Li + ions to form Li x Bi alloys. During the charge process, the Li x Bi alloys become Bi metals.…”

“…Bismuth ferrite (BiFeO 3 , abbreviated as BFO) is an interesting material with a perovskite structure and multiferroic properties . This material is also attractive as a high-capacity anode for battery applications due to its potential 9-electron conversion-alloy reaction mechanism. − Therefore, a high theoretical capacity of ∼770 mA h g –1 can be expected, which nearly doubles the capacity of graphite The average insertion potential is around ∼1.2 V vs Li + /Li in BFO, higher than that of graphite but lower than that of Li 4 Ti 5 O 12 (∼1.55 V vs Li + /Li), which is acceptable for anode application . Besides, both Bi and Fe elements are inexpensive, leading to a relatively low cost.…”

The pursuit of high-energy Li-ion batteries calls for the development of high-capacity electrode materials, especially anode materials. Graphite is a commercial anode but exhibits a moderate capacity of ∼350 mA h g −1 . In comparison, metal oxides provide higher capacities due to the potential to undergo conversion or alloy reactions. In this work, we revisit a bismuth ferrite (BiFeO 3 ) anode and reveal its underestimated performance by simple optimization of binders and electrolytes. We discovered that with the use of sodium carboxymethyl cellulose binder and fluoroethylene carbonate additives, this anode demonstrates a much-improved performance compared to that in previous reports. Specifically, it offers a high capacity of ∼750 mA h g −1 , an excellent rate capability at 1000 mA g −1 , and a stable cycling performance for 1050 cycles. When paired with an LiCoO 2 cathode, the full cell also demonstrates a promising cell voltage and rate performance. This work may motivate other similar materials to be used as high-capacity and long-cycling anodes for Li-ion batteries.

In this work, the effect of Ca doped BiFeO3 was investigated focusing on its microstructure, thermal and electrical properties. The compound BiFeO3 was prepared by solid state reaction at high temperatures. Samples of Ca-doped BiFeO3, Bi1-xCaxFeO3 with 0x0,5, were obtained by the same method of synthesis. Conventional sintering of compacts was carried out under specific conditions of temperature and holding time in order to maximize their density. The hybrid microwave sintering technique was also used to determine its influence on densification and on its microstructure. X-ray diffraction was used to study the crystalline structure of the obtained materials. The microstructure was observed using a scanning electron microscope. Thermal analyses allowed for identifying thermal events related to the Curie and Néel temperatures. Electrical measurements were carried out by impedance spectroscopy. The obtained results allowed to obtain an optimized route for preparing BiFeO3 with good density by the conventional method. In addition, they allowed for a better understanding of the influence of Ca on thermal, structural, electrical and dielectric properties of the compound.
