摘要:
Lithium-metal batteries with improved dimensional stability are presented along with methods of manufacture. The lithium-metal batteries incorporate an anode cell that reduces dimensional changes during charging and discharging. The anode cell includes a container having a first portion and a second portion to form an enclosed cavity. The first portion is electrically-conductive and chemically-stable to lithium metal. The second portion is permeable to lithium ions and chemically-stable to lithium metal. The anode cell also includes an anode comprising lithium metal and disposed within the cavity. The anode is in contact with the first portion and the second portion. The cavity is configured such that volumetric expansion and contraction of the anode during charging and discharging is accommodated entirely therein.
