dQ/dV plot from Galvanostatic Charge Discharge Data

dQ/dV plot from Galvanostatic Charge Discharge Data dQ/dV is known for differential capacity plot. It makes us understand better about the electrodes characteristics of lithium ion batteries. This article will help you plot a dQ/dV curve from Charge-Discharge statistics data of the battery. Background The applications of secondary batteries ranging from consumer electronics to electric vehicles has a common requirement of high performance, low cost, durable and reliable batteries. Out of many secondary energy storage devices, lithium ion batteries are able to meet the growing demand of energy storage due to its high energy density and ease for rechargeability. However, with current technology, the lifetime of the battery is often less than the desired product lifetime and tends for the repetitive replacement. A popular way to improve the life time and device safety of the battery is through analysing its state of health (SOH) and managing its degradation rates. Due to its complex mecha...
