Teaching Sodium To Behave: How A Simple Pattern Makes Anode-less Batteries Last

In an anode-less sodium battery, sodium deposits unevenly and grows into spiky shapes called dendrites, which can lead to huge problems. Creating a patterned current collector — tiny islands of carbon on copper — solves the problem as the collector guides sodium to the carbon islands, creates sharp boundaries that attract charged ions more predictably, and encourages sodium to spread sideways instead of shooting upward
