摘要： An anode-free lithium metal battery has a cathode current collector, a cathode comprising cathode active material, an electrolyte on the cathode opposite the cathode current collector, a first layer of particles deposited on the electrolyte, and an anode current collector. Each particle of the first layer consists of a first portion of a material having affinity to the electrolyte and a second portion of a material having affinity to lithium, the first portion and the second portion being discrete portions. Each particle is positioned such that the first portion is in contact with the electrolyte and the second portion faces the anode current collector.
