How do lithium-ion batteries reduce the danger of lithium dendrites during charging?

Lithium-ion batteries mitigate the danger of lithium dendrite formation during charging by utilizing specially selected carbon powders as the base for the anode.1

Instead of allowing metallic lithium to accumulate in a way that could form hazardous dendrites, these batteries insert lithium ions into the carbon structure to create a weak compound. This design effectively solves the problem of dendrite formation, providing a safer alternative to lithium-metal anode batteries, even though it results in a lower overall energy density. Additionally, maintaining safety in these systems requires precise electronic controls during the charging and discharging processes.1
