In this work, we evaluate the effect of Ni-doping LiMn2O4 spinels, LiNi x Mn2–x O4 (0.01 ≤ x ≤ 0.10) on the performance of lithium-ion hybrid supercapacitors (Li-HSCs) based on a mixture of 1 M lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) and a 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (EMITFSI) ionic liquid (IL) as the electrolyte and mesoporous carbon as the anode. Although the positive contribution of metal doping of lithium-ion insertion materials in the electrochemical properties is known for Li-ion batteries, this effect is little studied in battery/supercapacitor hybrid full cells based on these compounds, especially with the use of electrolytes based on ionic liquids at room temperature. This issue is addressed in the present work. Among all studied devices, the Li-HSC based on LiNi0.01Mn1.99O4 was able to deliver the highest energy density values, in the range of 21.7–40.9 W h kg–1. Also, the devices based on low nickel-content spinels (x ≤ 0.03) showed high performance with excellent cycling stability, being able to retain around 79–85% of its initial energy density after 1500 cycles of charge/discharge at 400 mA g–1.

“…Tang et al [136] observed the formation of the Mn 3 O 4 phase, a good source of soluble Mn 2+ , on the LMO surface after cycling. Doping of the spinel phase with Al [137], Yt [138], Ce [139], Nb or PO 4 [140] is useful for stabilizing capacity and mitigating the discharge voltage decay (Figure 3). Lithium transition metal oxides have an α-NaFeO2-type structure, which is a distorted rock salt superstructure.…”

All-solid-state batteries (SSBs) are one of the most fascinating next-generation energy storage systems that can provide improved energy density and safety for a wide range of applications from portable electronics to electric vehicles. The development of SSBs was accelerated by the discovery of new materials and the design of nanostructures. In particular, advances in the growth of thin-film battery materials facilitated the development of all solid-state thin-film batteries (SSTFBs)—expanding their applications to microelectronics such as flexible devices and implantable medical devices. However, critical challenges still remain, such as low ionic conductivity of solid electrolytes, interfacial instability and difficulty in controlling thin-film growth. In this review, we discuss the evolution of electrode and electrolyte materials for lithium-based batteries and their adoption in SSBs and SSTFBs. We highlight novel design strategies of bulk and thin-film materials to solve the issues in lithium-based batteries. We also focus on the important advances in thin-film electrodes, electrolytes and interfacial layers with the aim of providing insight into the future design of batteries. Furthermore, various thin-film fabrication techniques are also covered in this review.
