Rethinking the Rechargeable Battery with LiFeP0_4

摘要

It has always been believed that lithium ion batteries are slow to recharge, because the process involves the physical transport of ions, hence the hours that are needed to restore the batteries to full capacity. Paper #8 in the current list overturns this belief and reports a material through which ions like Li~+ can move within seconds, and it may be that one day they will be nearly as quick to recharge as ultra-capacitors, which can be recharged in seconds and are increasingly being used to store electrical energy.
