    Abstract: A battery cell core is hermetically sealed inside a casing, with conductive paths formed in the casing that individually connect cell subsets of the core to a battery management circuit for detecting individual failing cell subsets and for changing the battery output voltage by forming series/parallel connections between the cell subsets. In one version, the casing has a metal can with an opening of the can being sealed by a non-conductive cap that is sealed and bonded along its periphery to the can walls. In one aspect, the cap has edge metallization along its periphery where it is sealed to the can walls. In another aspect, the conductive paths are formed in the non-conductive cap. Various other embodiments are also described and claimed.

    Abstract: 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.
