The invention relates to a positive electrode plate for a high-rate rapid-charge lithium ion battery, a negative electrode plate and the high-rate rapid-charge lithium ion battery. The positive (negative) electrode plate is characterized by comprising a positive (negative) current collector, a positive (negative) active substance coating layer and an ion conduction coating layer, wherein the positive (negative) current collector is provided with two opposite surfaces, the positive (negative) active substance coating layer is coated on at least one surface of the positive (negative) current collector, and the ion conduction coating layer is coated on the positive (negative) active substance coating layer. The high-rate rapid-charge lithium ion battery comprising the positive electrode plateand the negative electrode plate is low in internal resistance, small in charge-discharge temperature rising, high in initial charge-discharge efficiency and good in cycle property and safety. 本申请涉及一种用于高倍率快充锂离子电池的正极极片、负极极片及高
