“…[11,12] Different anion species may strongly affect the ion association properties in solution, possible side reactions, and even redox reactions in electrode materials. [13][14][15] Recently, an electrolyte-dependent reaction mechanism has been identified for the high-rate δ-MnO 2 cathode, where the bulky anion bis(trifluoromethane)sulfonimide (TFSI − ) in aqueous electrolytes leads to a joint nondiffusion-controlled Zn 2+ intercalation and H + conversion reaction. [13] It has been shown that the electrolyte media, especially the species of the anion salts, can tailor the reaction mechanism of electrode materials.…”

Rechargeable aqueous Zn/MnO2 batteries are very attractive large‐scale energy storage technologies, but still suffer from limited cycle life and low capacity. Here the novel adoption of a near‐neutral acetate‐based electrolyte (pH ≈ 6) is presented to promote the two‐electron Mn4+/Mn2+ redox reaction and simultaneously enable a stable Zn anode. The acetate anion triggers a highly reversible MnO2/Mn2+ reaction, which ensures high capacity and avoids the issue of structural collapse of MnO2. Meanwhile, the anode‐friendly electrolyte enables a dendrite‐free Zn anode with outstanding stability and high plating/stripping Coulombic efficiency (99.8%). Hence, a high capacity of 556 mA h g−1, a lifetime of 4000 cycles without decay, and excellent rate capability up to 70 mA cm−2 are demonstated in this new near‐neutral aqueous Zn/MnO2 battery by simply manipulating the salt anion in the electrolyte. The acetate anion not only modifies the surface properties of MnO2 cathode but also creates a highly compatible environment for the Zn anode. This work provides a new opportunity for developing high‐performance Zn/MnO2 and other aqueous batteries based on the salt anion chemistry.

“…Theoretically, the anion doping/dedoping mechanism allows p‐type polymers to be used as anodes or/and cathodes for anion rocking‐chair batteries, or cathodes for dual‐ion batteries [7–9] . However, since the redox potential regions of most p‐type polymers are located at 3.0–4.5 V vs. Li + /Li, they are more appropriate as cathodes to construct dual‐ion batteries by coupling with relatively low‐potential anodes including carbons, inorganics, and n‐type organics.…”

p‐Type electroactive polymers are promising cathodes for dual‐ion batteries but cost‐effective candidates are still lacking. In this study, the p‐type polymer polyphenothiazine (PPTZ) is synthesized by a facile one‐step oxidation polymerization from the low‐cost phenothiazine (PTZ) monomer. As a cathode for rechargeable lithium batteries, PPTZ shows superior electrochemical performance to previously reported PTZ‐based polymers with complicated structures and syntheses. For example, PPTZ has a high reversible capacity of 157 mAh g−1 within 2.5–4.3 V vs. Li+/Li with an average discharge voltage of 3.5 V, and a high capacity retention of 77 % after 500 cycles. The highly reversible one‐electron redox mechanism of PPTZ is also investigated in detail by electrochemical testing, ex situ FT‐IR and X‐ray photoelectron spectroscopy, and DFT calculations. PPTZ has the potential to serve as an attractive p‐type cathode material for practical applications and the facile synthesis may be also extended to other polymer cathodes based on N‐heteroaromatic units.

Humans live today in a high‐tech and informationalized society. With the development of the emerging electronic information age, various electronic systems are inclined to be multifunctional and miniaturized. It is urgent to develop “small and powerful” micro‐batteries with flexibility and high electrochemical performance to meet the diverse needs of microelectronic components. However, low electrochemical performance exists in traditional microenergy storage devices, which fail to satisfy the energy needs for microdevices. Here, for the first time, a planar integrated flexible rechargeable dual‐ion microbattery (DIMB) is reported, which is fabricated from an interdigital pattern of graphite as an electrode and lithium hexafluorophosphate as an electrolyte. As a microbattery, the DIMB exhibits a high reversible capacity of 56.50 mAh cm−3, and excellent cycle stability with 90% capacity retention after 300 cycles under a high working voltage. The application of DIMB in microdevices, such as light‐emitting diodes (LEDs), digital electronic game consoles, and electrochromic glasses is also investigated, fully demonstrating its “small and powerful” performance. The integrated DIMB is a high‐voltage microdevice that reaches a nonpareil discharge voltage of about 100 V and a charging capacity of 102 mAh g−1. This dual ion‐based flexible microbattery could become a promising candidate for energy storage and conversion components in next‐generation microelectronic devices and integrated electronic devices.
