Effective passivation of lithium metal surfaces, and prevention of battery-shorting lithium dendrite growth, are critical for implementing lithium metal anodes for batteries with increased power densities. Nanoscale surface heterogeneities can be “hot spots” where anode passivation breaks down. Motivated by the observation of lithium dendrites in pores and grain boundaries in all-solid batteries, we examine lithium metal surfaces covered with Li2O and/or LiF thin films with grain boundaries in…

Galvanic Corrosion and Electric Field in Lithium Anode Passivation Films: Effects on Self-Discharge

Battery interfaces help govern rate capability, safety/stability, cycle life, and self-discharge, but significant gaps remain in our understanding at atomic length scales that can be exploited to

Lithium Diffusion Mechanism through Solid–Electrolyte Interphase in Rechargeable Lithium Batteries

The composition, structure, and the formation mechanism of the solid–electrolyte interphase (SEI) in lithium-based (e.g., Li-ion and Li metal) batteries have been widely explored in the literature.

First-Principles Study of the Surfaces and Equilibrium Shape of Discharge Products in Li-Air Batteries.

This work addresses the stability of various Li2O andLi2O2 surfaces and consequently, their crystallite morphologies using density functional theory calculations and ab initio thermodynamics and considers high-index surface terminations, which exhibit surprisingly low surface energies.

Review on modeling of the anode solid electrolyte interphase (SEI) for lithium-ion batteries

A passivation layer called the solid electrolyte interphase (SEI) is formed on electrode surfaces from decomposition products of electrolytes. The SEI allows Li+ transport and blocks electrons in

Lithium ion diffusion mechanism on the inorganic components of the solid–electrolyte interphase

The diffusion behavior of lithium (Li) ions on solid-electrolyte interphase (SEI) is fundamentally essential to Li metal batteries, whereas the underlying microscopic mechanism is still indistinct.

Electron leakage through heterogeneous LiF on lithium-metal battery anodes.

Grain boundaries between different SEI components, like LiF, have been suggested to accelerate Li+ transport, but using the non-equilibrium Green's function technique with density functional theory (NEGF-DFT), it is found that GBs enhance electron tunneling in thin LiF films by 1-2 orders of magnitude.

Polymorph Evolution Mechanisms and Regulation Strategies of Lithium Metal Anode under Multiphysical Fields.

The studies on the progress for delaying/suppressing/redirecting irregular Li evolution to enhance the stability and safety performance of Li metal batteries are reviewed, which are also categorized based on the multiphysical fields.

Interfacial Electronic Properties Dictate Li Dendrite Growth in Solid Electrolytes

The experimental observation of Li dendrite growth inside mechanically hard solid electrolytes (SEs) raised an important question: can hard SEs mechanically stop Li-dendrite growth? Here, we report a

Stability of Solid Electrolyte Interphase Components on Lithium Metal and Reactive Anode Material Surfaces

Lithium ion batteries (LIB) can feature reactive anodes that operate at low potentials, such as lithium metal or silicon, passivated by solid electrolyte interphase (SEI) films. SEI is known to

Stabilizing Lithium Metal Anodes by Uniform Li-Ion Flux Distribution in Nanochannel Confinement.

A new strategy to address the issue of dendrite growth by a polyimide-coating layer with vertical nanoscale channels of high aspect ratio provides a novel approach and a significant step toward stabilizing Li metal anodes.

Detection of subsurface structures underneath dendrites formed on cycled lithium metal electrodes.

Synchrotron hard X-ray microtomography experiments on symmetric lithium-polymer-lithium cells cycled at 90 °C show that during the early stage of dendrite development, the bulk of the dendritic structure lies within the electrode, underneath the polymer/electrode interface.

Dendrite-free lithium deposition via self-healing electrostatic shield mechanism.

This work shows a novel mechanism that can fundamentally alter dendrite formation in lithium-ion batteries as well as other metal batteries and transform the surface uniformity of coatings deposited in many general electrodeposition processes.

A highly reversible room-temperature lithium metal battery based on crosslinked hairy nanoparticles

A facile and scalable method of fabricating tough, freestanding membranes that combine the best attributes of solid polymers, nanocomposites and gel-polymer electrolytes are reported that are exceptionally effective in inhibiting dendrite growth in a lithium metal battery.

Lithium Electrodeposition Dynamics in Aprotic Electrolyte Observed in Situ via Transmission Electron Microscopy.

It was found that, even with minimal beam exposure, beam-induced surface film formation could alter the Li microstructure, and the electrochemical dissolution was seen to initiate from isolated points on grains rather than uniformly across the Li surface, due to the stabilizing solid electrolyte interphase surface film.

Grain Boundary Induced Conductivity in Li2O2

The dominant discharge product in Li–air batteries, lithium peroxide (Li2O2), is intrinsically a wide band gap insulator as a perfect crystal. Recent density functional theory studies have suggested

Twin boundary-assisted lithium ion transport.

It is proved that the lithium ions prefer to intercalate in the vicinity of the (101̅) TB, which acts as conduit for lithium-ion diffusion inside the nanowires, and density functional theory modeling shows that it is energetically preferred for lithium ions to accumulate near the TB compared to perfect neighboring lattice area.

Battery electrode surfaces are generally coated with electronically insulating solid films of thickness 1–50 nm. Both electrons and Li+ can move at the electrode–surface film interface in response to
