A method and system for charging a battery (e.g., including but not limited to lithium-ion batteries). The method may comprise: iteratively determining a plurality of charge profiles of the battery; based on the plurality of charge profiles, iteratively determining swelling of the battery; and adjusting a charge current during a subsequent charging of the battery.

Minimizing irreversible swelling during battery charging

Battery management systems and methods for use with lithium-ion batteries that employ silicon-based negative electrodes. The battery management systems and methods consider the lithiation/delithiation properties of silicon-based anode materials by considering voltage relaxation behavior. The battery management systems and methods may also be applied to other materials that similarly display an apparent hysteresis in the lithiation/delithiation processes and/or form multiple phases with different electrochemical properties.

Management systems and methods for silicon-containing lithium-ion batteries

A method for generating battery characteristics for a battery having a target composition includes identifying open-circuit potential (OCP) characteristics for two similar battery compositions having different proportions of elements. The OCP characteristics are converted to dQ/dV characteristics and linearly combined to derived a target dQ/dV characteristic. The target dQ/dV characteristic is integrated to derived a target OCP characteristic. A battery constructed of the target composition is operated according to the target OCP characteristic.
