1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Anode-free alkali metal batteries (AFAMBs) are emerging as a compelling strategy to surpass the cell-level energy density limits of Li-ion batteries while simplifying battery configuration. In these systems, the working anode forms in situ on a bare current collector and is continuously reshaped during cycling with a limited alkali metal inventory. As a result, the anode current collector is not merely a passive electron conductor, but a multifunctional interfacial platform that governs alkali metal nucleation, growth, stripping, and interphase evolution. This review examines the fundamental differences among anode-free lithium, sodium, and potassium systems and highlights key performance metrics for practical AFAMBs. Recent current collector engineering strategies developed for these chemistries are then summarized. Essential parameters shaping current collector design are identified, including electronic conductivity, alkali metal affinity, collector morphology, and interphase stability. Finally, practical design principles are presented to balance electrochemical performance with manufacturability under realistic operating conditions. This review aims to clarify the alkali metal-dependent design logic of current collectors and to provide guidance for the practical development of next-generation anode-free batteries.
