The output of battery foil in our country can meet the demand of aluminum foil for the development of automobile battery. The author suggests that in order to improve the performance of lithium-ion battery, especially the performance, it is appropriate to strengthen the research and development of new battery.
The proposed surface architecture and working mechanism of lithium supplement could effectively eliminate the remaining challenges of high-capacity Al anodes, promoting the possibility of using commercial aluminum foils as single-material anodes for high energy density lithium-ion batteries.
There are two kinds of aluminum foil for lithium-ion battery: flat foil, with high strength, high conductivity and flat, and surface modified foil.
[new development of aluminum foil for lithium-ion battery] during the two decades from 2016 to 2035, the compound growth rate of aluminum foil for lithium-ion battery in China and for the whole automobile can reach 15% or even higher.
On April 26th this year, 12 μ m hot-rolled 1100 dual-photovoltaic lithium battery foil was mass-produced in Guangxi Nannan Aluminum foil Co., Ltd., a subsidiary of South-South Aluminum Group.
In summary, low-cost aluminum foils are employed as single-material anodes for Li-ion batteries that can match various commercial cathodes and potentially achieve higher energy densities. The roles of pre-lithiation, phase change, and morphology evolution on commercial Al foil anodes are comprehensively studied in Al||NCM full batteries.
