Thus, obtained lithium-ion batteries have an excellent discharge capacity of 165 mAh g − 1 at 0.1 C-rate and 123 mAh g −1 at 5 C-rate and a greater cycling performance over 100 cycles. Thus, this investigation delivers inspiration for the expansion of inorganic-organic nanocomposite separators for next-generation lithium-ion batteries.
1.4 million electric vehicles ENTEK has committed to the transformational expansion of its US lithium-ion battery separator footprint at a scale and a pace to meet the US Department of Energy imperative for a sustainable and resilient domestic US lithium battery supply chain.
As a vital part of lithium-ion batteries (LIBs), the separator is closely related to the safety and electrochemical performance of LIBs. Despite the numerous membranes/separators available commercially, their thermal stability and service life still severely limit the efficiency and reliability of the battery.
By 2025, ENTEK will have completed its first major expansion of lithium-ion separator production in the US with continued expansion through 2027 totalling 1.4 billion square meters of annual production. When complete, this initial expansion will produce enough separator material to power 1.4 million electric vehicles.
It allows ions to migrate during the charge-discharge process [5, 6], and the separator does not directly contribute to any battery reaction. The conventionally LIBs separators used on a large scale are polyolefin separators, which are polyethylene (PE) and polypropylene (PP) or their multilayer formations [7, 8].
However, such thick separators come at the expense of less free space for accommodating active materials inside the battery, thus impeding further development of next-generation lithium-based batteries with high energy density.
Thin separators with robust mechanical strength are undoubtedly prime choice to make lithium-based batteries more reliable and safer. Recently, great accomplishments have been achieved for advanced thin separators used in LIBs and a detailed discussion is following in this section. 5.1. Functionalized polyolefin separators
