Title:
LITHIUM ION BATTERY AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/168517
Kind Code:
A1
Abstract:
A lithium ion battery and a preparation method therefor. The lithium ion battery comprises: a first electrode current collector (101), a first electrode layer (102), an electrolyte layer (103), a second electrode layer (104), and a second electrode current collector (105) that are stacked; and also comprises a first electron transport layer (106) and/or a second electron transport layer (107), wherein the first electron transport layer (106) is disposed between the first electrode layer (102) and the first electrode current collector (101), and the second electron transport layer (107) is disposed between the second electrode layer (104) and the second electrode current collector (105). In the lithium ion battery, the provision of the first electron transport layer (106) and/or the second electron transport layer (107) can improve the charge and discharge efficiency of the lithium ion battery.
