The volumetric energy density, on…

Lithium-ion (Li-ion) batteries had been the power of choice for smartphones and various other portable devices. However, lithium polymer (LiPo) batteries are now gradually replacing Li-ion as the mainstream battery for most smart devices. We’re going to discuss the differences between these two types of batteries in today’s Battery Monday.  Housing Material Lithium-ion batteries consist of positive…
