Li-ion batteries have no memory effect, a detrimental process where repeated partial discharge/charge cycles can cause a battery to ''remember'' a lower capacity. Li-ion batteries also have a low self-discharge rate of around 1.5–2% per month, and do not contain toxic lead or cadmium. High energy densities and long lifespans have made Li
