Aqueous batteries are considered as promising alternative power sources due to their eco-friendly, cost-effective, and nonflammable attributes. Employing organic-based electrode materials offers further advantages toward building greener and sustainable systems, owing to their tunability and environmental friendliness. In order to enhance the energy and power densities, superconcentrated aqueous electrolytes, such as water-in-salt electrolytes (WiSE), have renewed the interest in aqueous batteries due to their enhanced stability and much wider electrochemical stability window (>1.23 V) compared with the traditional aqueous electrolytes. Here, we present a perylene diimide-based electrode material (PDI-Urea) as an appealing anode for aqueous potassium energy storage systems and investigate their electrochemical performance in three WiSE electrolytes, namely, 30 M potassium acetate, 40 M potassium formate and 30 M potassium bis(fluorosulfonyl)imide (KFSI). To explore the potential of PDI-Urea for potassium-based electrochemical energy systems, we fabricated full cell devices such as aqueous potassium dual-ion battery (APDIB) and aqueous K-ion battery (AKIB) and studied their electrochemical properties with 30 M KFSI electrolyte. The full cell K-ion battery, using a PBA cathode, exhibited excellent electrochemical performance with good rate capability and impressive capacity retention of 91% upon 1000 cycles. Further, the reaction mechanism of the electrodes is systematically analyzed using ex-situ studies.

“…However, the surface heterogeneity, doped heteroatoms, and functional groups catalyze the electrolyte decomposition. 57 Therefore, the improvements are either marginal or perform poorly during long-term cycling at a standard current rate. Moreover, the chemical formation of carbon coating from its precursor on the LNMO surface is challenging due to the possibility of carbothermal reduction of the metal oxide core.…”

LiNi0.5Mn1.5O4 (LNMO) has the advantages of high voltage output (4.7 V), fast charging capability, and better thermal stability, which make it suitable for future applications in lithium-ion batteries. However, the limitation in cycle life due to the electrolyte and the structural instability during high-voltage cycling to 5 V is a major drawback. Further, the decomposition of the electrolyte on the highly reactive surface of LNMO plays a critical role in catalyzing the structural disintegration. The issue can be mitigated via the surface carbon coating on LNMO. Herein, a method to integrate soft carbon on LNMO is reported, which bypasses the drawback of lattice oxygen loss during the conventional carbon coating on metal oxides. The soft carbon derived from the pitch precursor with its unique blend of physical properties renders the LNMO surface less susceptible to electrolyte attack. As a result, capacity retention enhances by 25.6%, and the coulombic efficiency improves by 1.5% over 500 cycles in a carbonate-based 1 M LiPF6 electrolyte. The soft carbon regulates the interfacial composition balanced in LiF/Li x PO y F z and reduces the growth of the charger-transfer resistance. Moreover, the strategy also decreases the Mn dissolution by 18%.
