A non‐aqueous secondary battery has been constructed by using Zn metal as the anode and chemically synthesised PEDOT as the cathode, with a 1‐ethyl‐3‐methylimidazolium dicyanamide ionic liquid as the electrolyte, which avoids dendritic growth processes on the Zn surface upon charge/discharge cycling. The novel Zn/PEDOT rechargeable cell shows high efficiency and cycling ability, performing over 320 cycles with no indication of short circuit. Both the Zn and PEDOT surfaces showed minimal signs of degradation, suggesting that a Zn/PEDOT electrochemical device would be capable of extended cycle life under numerous charge/discharge cycles.

Many components of the cathode play roles in self-discharge performance of the rechargeable hybrid aqueous battery (ReHAB). Effects of amount and type of conductive additives are investigated, and carbonaceous material of low specific surface area yields the best performance. The self-discharge mechanism involves the cathode active material and contains a reversible and an irreversible process. The reversible portion is predominant and related to lithium re-intercalation into the LiMn 2 O 4 spinel framework, accompanied by Zn dissolution into the electrolyte. The irreversible portion of self-discharge possibly involves decomposition of LiMn 2 O 4 in the acidic electrolyte, and is much less extensive than the reversible process. Self-discharge refers to the loss in stored charge of a battery without connection between its electrodes as a consequence of internal chemical reactions. Self-discharge processes can be tested in a loadfree state for a fixed time. Two self-discharge reactions are possible in a Li-ion cell: one is chemical and the other electrochemical. Because of their reactivity, charged cells can undergo side reactions, and factors such as purity of the active material or electrolyte, the specific surface area of the electrodes, conductors, binders or separators can have effect on the self-discharge performance. These reactions are mostly irreversible while electrochemical reactions can be reversible. For example, lithium re-intercalation can lead to self-discharge of Li-ion batteries, as has been demonstrated by many researchers who have studied the different factors that could affect self-discharge of the cells. 1-4After ARLBs were introduced in 1994 by Dahn's group, 5 various papers have been published describing the use of aqueous electrolytes in Li intercalation systems. [6][7][8][9][10][11][12][13][14][15][16][17][18][19] One of them, a novel Rechargeable Hybrid Aqueous Battery (ReHAB) system was developed in the Chen research group. 20 The combined performance attributes of the ReHAB indicate that it constitutes a viable alternative energy storage system, with potential to replace the commercial lead-acid system, and can be used for large scale energy storage applications. Commercialization of this technology, however, depends on the investigation of a number of key electrochemical parameters, one being the self-discharge performance of the ReHAB cell.To the best of our knowledge, no studies regarding the extent and mechanisms of self-discharge in ARLBs have been published. Here, we report on the effect of different components of the cathode on the self-discharge performance of the ReHAB, aiming to evaluate the mechanism the self-discharge process. ExperimentalThe composite cathodes were prepared by mixing 80 wt% of LiMn 2 O 4 (MTI Corporation), 10 wt% conductive additive (SuperP-Li (SP-Li) or KS6 Graphite (KS6) from Timcal, or Ketjen Black, EC300J (KB300), Akzo Nobel) and 10 wt% polyvinylidene fluoride (PVDF, Kynar, HSV900) binder.

density. Therefore, developing highcapacity anode and cathode materials or new battery systems have drawn extensive attentions. [6,[21][22][23][24][25][26][27][28] Metal anodes, especially those with high-capacity and low-cost are promising alternative anode materials for LIBs in replace of graphite anode. [29][30][31][32][33][34] Generally, the metal anodes electrochemically alloy/ de-alloy with Li + to complete the battery reaction, which can store more energy than the intercalation/deintercalation mechanism in graphite. Table 1 displays the electrochemical properties of typical metallic anodes (Al, Sn, Zn, Mg, Sb, and Bi) with Li and graphite for comparison. While the graphite anodes suffer from low capacity (372 mA h g −1 ) and Li anodes suffer from severe safety issues caused by lithium dendrites, these metal anodes have many advantages in terms of high theoretical capacities, moderate operation potential for less dendrites formation, high abundance and low cost. [35] For example, aluminum has high theoretical capacity (993 mA h g −1 or 1411 mA h cm −3 for LiAl) with moderate potential plateau (≈0.38 V vs Li + /Li). [35,36] Considering both of the capacity increase and voltage drop by using metal anodes in a LIB model, Obrovac et al. calculated the volumetric energy increase in comparison to graphite based commercial battery (Table 1). [37] In such a model, the volumetric energy densities could be increased by different extents ranging from 10-42% when metal anodes were used. It is worth noticing that some recent studies have raised the idea of directly using metal foil as active anode material and simultaneously current collector. [38,39] This strategy can eliminate the usage of binder and conductive carbon black for anode preparation, simplify the battery processing steps, and also increase the loading amount of active materials, thus further enhancing the energy density and reducing the battery prices.While the metal anodes show good potential for application in high-performance LIBs, the main challenge for these metallic anodes is their large volume change caused by lithiation/delithiation process during cycling. [37,40,41] As the lithiation proceeds more deeply, the volume change becomes more severely for alloying anodes. For instance, the volume change of Sn (260%, Li 4.4 Sn) is larger than Al (97%, LiAl). The huge volume change could cause crack and pulverization of metal anodes, resulting in quick capacity decay and short cycling life. [42][43][44][45][46] Besides, metallic anode materials usually exhibited high first-cycle capacity loss due to their high reactivity withThe ever-growing market of portable electronic devices and electric vehicles has significantly stimulated research interests on new-generation rechargeable battery systems with high energy density, satisfying safety and low cost. With unique potentials to achieve high energy density and low cost, rechargeable batteries based on metal anodes are capable of storing more energy via an alloying/de-alloying process, in comparison to tradi...
