Lithium-ion batteries have a memory effect that reduces capacity if recharged before full discharge.

Is it true that lithium-ion batteries have a memory effect that reduces capacity if recharged before full discharge?

Partly. Several reference and peer-reviewed sources state that lithium-ion batteries have no memory effect, while one study reports a 'memory effect' in thick electrodes that is a different phenomenon tied to cycling history rather than recharge-before-full-discharge. The evidence partially addresses the claim but does not fully settle it.
