“…As the market for electric vehicles is grown excessively, the development of advanced battery systems that can offer high energy density is required to overcome the energy and power density limitation of conventional lithium-ion batteries. [1][2][3][4][5] Among them, lithium-metal batteries (LMBs) are considered as an ideal energy storage system because Li metal exhibits the lowest redox potential of À 3.04 V (vs. Standard Hydrogen Electrode) and tenfold higher specific capacity (3860 mA h g À 1 ) than conventional graphite anode (376 mA h g À 1 ). [6][7][8][9][10][11] Despite these promising features, the inevitable formation and growth of Li dendrites hinders the practical application of LMBs.…”

Commercialization of lithium-metal batteries is impeded by Li dendrites. Realizing a high Li + transference number is an effective strategy to suppress the formation of Li dendrites by alleviating the Li + concentration gradient at the Li metal surface. Accordingly, various materials that facilitate Li + transfer have been investigated in separator engineering. Herein, we designed a functional separator incorporating halloysite nanotubes (HNTs) as a functional material and polydopamine (PDA) as a polymeric binder. PDA plays a significant role in improving electrolyte affinity as it renders the overall backbone of PE hydrophilic. Moreover, the PDA/HNTs/PE separator shows a high Li + transference number (0.603) owing to the interactions of HNTs: 1) the electrostatic attraction between the negatively-charged silicon layer and Li + , and 2) dipole-dipole interactions between HNTs and electrolyte solvent molecules, which reduce the degree of Li + solvation. Consequently, dendrite-free Li deposition was observed with the PDA/HNTs/PE separator, improving the electrochemical performance of Li/Li symmetric cells and Li/LiFePO 4 full cells.

“…The fast-growing demand for electronic devices, drones, and electric vehicles (EVs) has massively increased in recent years. [1][2][3][4][5][6] However, over the past four decades of research and development, the energy density of state-of-the-art LIBs has reached a peak. Replacing the current traditional graphite anode (372 mA h g À1 theoretical specific capacity) in LIBs with a Li metal anode, which has a substantially higher theoretical specific capacity (3860 mA h g À1 ) and a low electrochemical potential (À3.040 V vs. the standard hydrogen electrode), has great prospects for boosting the battery energy density.…”

<p>Aluminum (Al) current collector, an important component of lithium-ion batteries (LIBs), plays a crucial role in affecting electrochemical performance of LIBs. In both working and calendar aging of LIBs, Al suffers from severe corrosion issue, resulting in the decay of electrochemical performance. However, few efforts are devoted to the research of Al compared to anode and cathode materials, electrolyte, and even separators in LIBs. Here, the recent research advance in Al corrosion and protection is reviewed. We first briefly overview Al corrosion mechanism and its affecting factors. Then, the advanced technologies used to evaluate the electrochemical, morphology and chemical properties of Al are summarized in order to uncover the Al corrosion mechanism in LIBs. Next, we review the Al protection strategies in Al, electrolyte, and inhibitors with function mechanism, materials selection and their structural design. Finally, we outlook the future research direction in Al corrosion and protection. This review provides experimental and theoretical supports in understanding Al corrosion and development of Al anticorrosion, which will be beneficial to the research communities including corrosions, advanced materials, and energy storage devices.</p>
