This article discusses the issue and describes cost-effective integrated solutions that can also add extra user benefits, including state-of-charge and state-of-health monitoring.
Going back in history, perhaps hundreds of chemistries have been proposed for batteries. These have ranged from the original copper,

The power-semiconductor switches used in power supplies and inverters are based on two technologies, namely MOSFETs and IGBTs. MOSFETs can operate at relatively high switching frequencies significantly above 30 kHz but, unlike IGBTs, they have a very large chip surface area.
A new generation of IGBT modules f
