A modeling preprint suggests sodium metal can become isolated at grain-boundary junctions, survive stripping, and fuel renewed penetration in later cycles.

Simulations find a low lithium-transfer barrier at a gallium-doped LLZO interface, while contact area and constant-charge modeling complicate the picture.

A simulation preprint finds that expansion speeds lithium movement in Li3YCl6 and compression slows it, without changing the underlying transport pattern.

A modeling preprint separates changing lithium contact from accumulating interphase damage and predicts how faster discharge could reverse an energy advantage.

A preprint’s calculations show what positive and negative insertion energies mean, and why a migration barrier is a different test. Battery implications remain conditional.

Temperature-dependent current tests link sodium contact loss to a boundary barrier, while a tin–sodium layer lowers it in model cells; durability remains open.

A March 2026 preprint compares dense and three-layer solid electrolytes, using impedance and lithium profiles to explain a 25-cycle capacity gap.

A theoretical preprint models how cracks let metal cross ceramic electrolytes, including slower growth below critical current and variation between samples.

Nanoscale imaging reveals shared lithium and sodium growth rules, while sodium removal leaves a residual layer whose chemistry is still unknown.

Neutron depth profiling and reflectometry probe a buried lithium–solid-electrolyte contact at different scales, revealing why one test can miss a graded transition.
