Abstract:
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.
