摘要： A positive electrode active composite for lithium-ion batteries, consisting of 60%-99% by weight of a lithium iron phosphate material with an olivine structure and 1%-40% by weight of a layered ternary material. A lithium-ion battery, whose positive electrode includes such active composite, is provided, and in normal use, an upper voltage range is controlled between 3.8-4.0 V. When there is a certain capacity attenuation, a battery voltage can be increased to a range of greater than or equal to 4.1 V and less than or equal to 4.4 V for activation. Under the activation voltage, the lithium-rich ternary material can compensate for the active lithium loss after the battery aging.
