Abstract: An anode active material comprises a silicon-carbon secondary particle comprising a composite having an exterior conformal carbon coating and formed of type I primary particles. Each type I primary particle comprises a core particle of interconnected silicon, the interconnected silicon formed of nano-sized silicon particles each connected to at least one other particle, inner pores internal to the core particle and defined by the interconnected silicon, an internal carbon coating on internal wall surfaces of the inner pores and a conformal carbon coating on the core particle.

Abstract: A battery may include an enclosure that defines an interior volume, an electrode cell disposed within the interior volume, and a pair of retaining elements. The electrode cell may include a pair of notches formed therein. The pair of retaining elements may be disposed within volumes defined by the pair of notches. The pair of retaining elements may be connected to the enclosure and may be configured to engage with a respective notch of the pair of notches to arrest movement of the electrode cell with respect to the enclosure.

Abstract: The disclosed technology relates to a battery utilizing a dampening layer to prevent a failure of the battery. The battery includes an enclosure, a set of electrodes enclosed within the enclosure, and a dampening layer disposed within the set of electrodes. The dampening layer partitions the set of electrodes into a first subset of electrodes and a second subset of electrodes. The dampening layer is configured to absorb a mechanical impact on the enclosure to prevent a failure of at least one of the first subset of electrodes and the second subset of electrodes. The dampening layer may be formed at least one of a polymer, metal, and ceramic.

Abstract: A battery may include an enclosure and an electrode cell disposed within the enclosure. A first pair of notches may be formed in the enclosure. Each notch of the first pair of notches may include a protrusion that extends into the enclosure. A second pair of notches may be formed in the electrode cell. The first pair of notches may be aligned with the second pair of notches. The protrusions may be configured to engage with the second pair of notches when the cell moves within the enclosure.
