“…This study suggests that novel migration channels of lithium ions can be generated by tuning the content of different phases in LiMn 0.5 Fe 0.5 PO 4 with the introduction of Li + /Fe 2+ antisite defects . In addition, the effect of Li + /Ni 2+ antisite defects on the properties of lithium ion diffusion in layered nickel‐rich cathode (LiNi 0.8 Co 0.15 Al 0.05 O 2 ) was analysed by Tang et al . The authors proposed that defective lithium ions with low valence in the nickel layer could weaken the repulsive interaction at the saddle point, and nickel ions with high valence in the lithium layer could push the neighbouring lithium ions by improved electrostatic repulsion.…”

To this end, electrical energy storage (e.g., batteries, supercapacitors) has become a key supporting technology for the utilization of intermittent energy sources (e.g., sun, wind, nuclear energy). [3] Clearly, lithium-ion batteries (LIBs) are by far the most important electrochemical energy storage devices available for portable electronics, power tools, and electric vehicles on the market. However, LIBs suffer from the slow ion diffusion in electrode bulk, resulting in commercially achievable energy density of 80-270 W h kg −1 , and power density typically <1000 W kg −1 at the cell level. Thus this greatly restricts their fast-charge and high-power applications. [4] In contrast, supercapacitors can be charged within seconds and provide higher power density (≥10 kW kg −1 ), but the energy stored is ≈1-2 orders of magnitude less than LIBs (basically ≤ 10 Wh kg −1 ). [5][6][7] Therefore, both conventional batteries and supercapacitors can't fully satisfy certain application scenarios such as hybrid electric vehicles (HEVs) and regenerative braking energy harvesting, which require high energy density, high power density, and long-term cycle stability. To overcome this issue, the new-type BSHDs, as one of the key energy storage technologies in multi-scenario applications, are recently developed to balance the gap between batteries and supercapacitors, and can simultaneously realize the "double high" trend of high energy density and high power density. [4] Although BSHDs have made some progress in recent years through the modification of cathode materials, anode materials, and electrolytes, as well as the use of pre-lithiation or other techniques, the reported energy density of commercialized BSHDs is still lower than 30 Wh kg −1 , [8,9] and no significant breakthrough improvement in "double high" goal of "100 Wh kg −1 & 100 kW kg −1 " has been achieved. Therefore, how to further promote the high-quality development of BSHDs is still worthy of in-depth investigation by academics and industrial counterparts. [8] As shown in Figure 1, the hybridization of batteries and supercapacitors for BSHDs can be divided into four types, including external serial hybrids (ESHs), external parallel hybrids (EPHs), internal serial hybrids (ISHs), and internal parallel hybrids (IPHs). [10] Based on the hybridization mode, BSHDs can be divided into two types: simple physical
