Title:
電気エネルギ蓄積素子並びにその製造方法及び製造装置
Document Type and Number:
Japanese Patent JP6822844
Kind Code:
B2
Abstract:
In the electrical energy storage element in accordance with the invention, a plurality of electrochemical cells that are each formed with a cathode and an anode as electrodes and an electrolyte are arranged stacked above one another. They are enclosed at one side by a top plate formed from an electrically conductive material, in particular aluminum, and at the oppositely disposed side by a base plate formed from an electrically conductive material, in particular aluminum. The base plate is coated by a cathode or by an anode and the cover plate is coated in a complementary manner by an anode or by a cathode. The anodes and cathodes are each formed at oppositely disposed surfaces of an electrically conductive carrier film which preferably comprises aluminum, copper, steel or an electrically conductive plastic. An outer peripheral margin is present at the carrier film that is free of electrode material and connects adjacent electrochemical cells to one another in a hermetically sealed manner with respect to the environment by means of a sealing and bonding agent. The anodes comprise a lithium titanate (LTO) having a spinel structure and the high-voltage cathodes are formed from a lithium nickel manganate (LNMO) having a spinel structure or from lithium phosphates (LP) in an olivine structure. With a gel electrolyte, a respective separator layer is present between the electrolyte and an electrode of an electrochemical cell and with a solid electrolyte no separator layer is present.
