“…Figure 2a shows the charge/discharge curves of the Mn-PBA film in LIB. In the 1st discharge process, we observed irreversible capacity of 1400 mAh/g at voltage of 0.5 V. The capacity (=1400 mAh/g) of the 1st discharge process is slightly higher than those reported in literatures: 1000 mAh/g [16], 600 mAh/g [17], 1100 mAh/g [18], 1000 mAh/g [19], and 850 mAh/g [20]. The high irreversible capacity is probably ascribed to the thin film electrode and complete reduction reaction of PBA.…”

The experiments performed by Piernas-Muñoz et al [19] and Sun et al [20] imply that the low voltage charge/discharge behavior is ascribed to Fe metal. Thus, the mechanism of the low voltage behavior is controversial even though the high reversible capacity and low voltage are promising.…”

Abstract:Recently, Prussian blue analogues (PBAs) have been reported to exhibit a low voltage charge/discharge behavior with high capacity (300-545 mAh/g) in lithium-ion secondary batteries (LIBs). To clarify the mechanism of low voltage behavior, we performed ex situ synchrotron radiation X-ray diffraction (XRD) and ex situ X-ray absorption spectroscopy (XAS) of a film of Na 1.34 Mn[Fe(CN) 6 ] 0.84 ·3.4H 2 O without air exposure. After the 1st discharge process, the XRD patterns and X-ray absorption spectra around the Fe and Mn K edges reveal formation of Fe and Mn metals. After the charge process, the XRD pattern reveals formation of Fe 2 O 3 . Based on these observations, we ascribed the low voltage behavior mainly to the conversion reaction of Fe 2 O 3 : 6e − + Fe 2 O 3 + 6Li + 2Fe +3Li 2 O.

Prussian Blue Analogs for Rechargeable Batteries

SummaryNon-lithium energy storage devices, especially sodium ion batteries, are drawing attention due to insufficient and uneven distribution of lithium resources. Prussian blue and its analogs (Prussian blue analogs [PBAs]), or hexacyanoferrates, are well-known since the 18th century and have been used for hydrogen storage, cancer therapy, biosensing, seawater desalination, and sewage treatment. Owing to their unique features, PBAs are receiving increasing interest in the field of energy storage, such as their high theoretical specific capacity, ease of synthesis, as well as low cost. In this review, a general summary and evaluation of the applications of PBAs for rechargeable batteries are given. After a brief review of the history of PBAs, their crystal structure, nomenclature, synthesis, and working principle in rechargeable batteries are discussed. Then, previous works classified based on the combination of insertion cations and transition metals are analyzed comprehensively. The review includes an outlook toward the further development of PBAs in electrochemical energy storage.

Synthesis of Manganese‐Based Prussian Blue Nanocubes with Organic Solvent as High‐Performance Anodes for Lithium‐Ion Batteries

et al. 2019

Prussian blue analogue KxMnFe(CN)6·yH2O (m‐KMHCF) nanocubes with an average edge length of about 60 nm were synthesized by a simple hydrothermal reaction involving methanol. The microscopic size of m‐KMHCF nanocubes could be easily reduced to less than 100 nm as methanol was added to the reaction, over a long range of reaction temperatures and reaction times. As anode material for lithium‐ion batteries, the m‐KMHCF electrode delivered a high specific capacity of over 900 mAh g–1 at a current density of 100 mA g–1 after 50 cycles. In addition, it provided stable rate capability and lithium storage performance at the high current density of 382.3 mAh g–1 at 5000 mA g–1. It is worth noting that the capacity continued to rise during the galvanostatic charge‐discharge, and the specific capacity increased after charging and discharging at the large current. This phenomenon and the excellent electrochemical performance are mainly derived from the smaller microscopic size, which further led to crystal particle refinement during charge‐discharge.
