Bottlenecks‐Breaking in Zinc‐Iodine Batteries Toward Practical Implementation: A Review and Perspective

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Aqueous zinc–iodine batteries (Zn–I2Bs) offer promise for grid storage due to safety and cost advantages yet face critical bottlenecks: severe self‐discharge (polyiodide shuttling and HER), limited energy density, sluggish kinetics, and zinc anode instability.

Orchestration of Climate Action in Municipalities: A Collective Capacity Approach

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT Municipalities are increasingly positioned as key actors in enabling local climate action, yet their ability to mobilise societal actors remains insufficiently understood. This study examines how municipal officials in six Finnish municipalities from different local contexts understand and operationalise collective capacity for climate action,
