Title:
高容量合金アノード及び同アノードを含むリチウムイオン電気化学セル
Document Type and Number:
Japanese Patent JP2013546138
Kind Code:
A
Abstract:
A lithium-ion electro-chemical cell that includes a cathode that includes an electrochemically-active metal oxide coating on a first current collector, an electrolyte, and an anode that includes an electrochemically-active alloy coating on a second current collector. Both the anode and the cathode have a reversible capacity of greater than 4.5 mAh/cm2 per coated side. The metal oxide coating typically comprises cobalt, manganese, nickel, or a combination thereof. The reversible capacity of the cathode is within 15% of the reversible capacity of the anode.
