6 FAQs about [Lithium battery conversion loss]
Does loss of lithium reduce the energy density of lithium-ion batteries?
Nature Energy 1, Article number: 15008 (2016) Cite this article Loss of lithium in the initial cycles appreciably reduces the energy density of lithium-ion batteries. Anode prelithiation is a common approach to address the problem, although it faces the issues of high chemical reactivity and instability in ambient and battery processing conditions.

There is an intensive research effort in suppressing the first-cycle lithium loss in lithium-ion batteries.
Why do lithium ion batteries have a reversible Li + loss?
The continuous SEI formation thickens the SEI and increases the internal resistance of batteries. Li deposition on anodes is an undesirable process, which occurs if the charge rate exceeds the speed at which Li + ions insert anodes. The poor Li plating/stripping efficiency in traditional carbonate electrolytes aggravates the irreversible Li + loss.
Why do rechargeable lithium batteries lose power?
Rechargeable lithium-based batteries generally exhibit gradual capacity losses resulting in decreasing energy and power densities. For negative electrode materials, the capacity losses are largely attributed to the formation of a solid electrolyte interphase layer and volume expansion effects.
