摘要: An apparatus includes a charging circuit configured to electrically connect to a plurality of batteries during manufacture of a set of batteries that includes the plurality of batteries. The apparatus further includes a battery bank configured to supply charge to the plurality of batteries during a formation process of each battery of the plurality of batteries and to receive the charge from the plurality of batteries during the formation process. The battery bank has at least one attribute that enables the battery bank to concurrently charge, for each plurality of batteries of the set of batteries, a particular number of batteries based on at least a threshold charging rate and to concurrently discharge, for each plurality of batteries of the set of batteries, the particular number of batteries based on at least a threshold discharging rate.

摘要: Systems and methods which provide battery configurations for delivering high power while maintaining high energy density are described. Embodiments provide cylindrical batteries configured to deliver high energy density while having high power density at least in part through an electrode configuration disposing electrode material for the cathode and/or anode over an extended length of a longitudinal edge of the respective cathode or anode. An electrode configuration may provide for a continuous length of electrode material disposed along a longitudinal edge of at least one of the cathode or anode. Additionally or alternatively, an electrode configuration may provide for a plurality of electrode tabs of electrode material spaced out along a longitudinal edge of at least one of the anode or cathode.

摘要: Disclosed is a relieved weld plate for affixing to a battery core to provide an electrical connection between the battery core and a terminal of a battery. The relieved weld plate includes a conductive face configured for affixing to an electrode of the battery core. The relieved weld plate further includes one or more pathways disposed in the conductive face. The one or more pathways are configured to facilitate at least one of an ingress of a first material into the battery core or an egress of a second material out of the battery core.

摘要: Systems and methods which provide lithium-ion battery configurations with high energy density are disclosed. Embodiments provide lithium-ion batteries comprising an anode that includes 30 to 85 wt.% silicon, thereby facilitating high energy density and high N:P ratio for the lithium-ion batteries. The high N:P ratio further enables fast charging and low temperature charging capabilities of the lithium-ion batteries.
