The present disclosure is related to electrochemical cells and associated methods. According to certain embodiments, the electrochemical cells comprise an electronically insulating region. In some embodiments, the electronically insulating region can be mechanically compliant. In some embodiments, the insulating region may comprise multiple layers (e.g., mechanically separable layers). The use of such arrangements can, according to certain embodiments, reduce the degree to which the electronically insulating region is breached by lithium dendrite growth.
