Structural degradation of cathode supplies, which include Li+/Ni2+ cation mixing in nickel-abundant components. This manifests as "electrode saturation", loss of cyclable Ah cost and as being a "voltage fade". These early tries to develop rechargeable Li-ion batteries utilised lithium metallic anodes, which had been ultimately abandoned due to security worries, https://social40.com/story4539731/lithium-battery-manufacturer-can-be-fun-for-anyone
