Sinusoidal ripple-current charging has previously been reported to increase both charging efficiency and energy efficiency and decrease charging time when used to charge lithium-ion battery cells. In this paper, we show that no such effect exists in lithium-ion battery cells, based on an experimental study of large-size prismatic cells. Additionally, we use a physics-based model to show that no such effect should exist, based on the underlying electrochemical principles.

具有挑战性的锂离子电池正弦纹波电流充电


此前有报道称，正弦纹波电流充电可提高充电效率和能源效率，并在用于锂离子电池充电时缩短充电时间。在本文中，我们基于大尺寸棱柱形电池的实验研究表明，锂离子电池中不存在这种效应。此外，我们使用基于物理的模型来表明，根据基本的电化学原理，不应存在这种效应。
