Packaging. Packaging process refers to a process in which a battery cell and a module are combined in series and parallel and put them in a frame, to protect them from external impact (vibration or heat) and to increase efficiency. So an important factor in battery packaging is how much battery packs protect internal elements of the battery.

Methodologies to fabricate battery separators are sorted into two methods: (1) wet method and (2) dry method . The separator prepared by the wet method has interconnected pores through the entire area (Figure 2 a). On the other hand, the separator fabricated by dry method has plenty of slit-like pores (Figure 2 b).
Separator, a vital component in LIBs, impacts the electrochemical properties and safety of the battery without association with electrochemical reactions. The development of innovative separators to overcome these countered bottlenecks of LIBs is necessitated to rationally design more sustainable and reliable energy storage systems.
In addition, as another important development trend of battery separators, smart separators are receiving increasing attention. Smart separators can monitor the operating status of batteries in real time, including the transmission of lithium ions and temperature changes in batteries.
The 'dry' method includes uniaxial and biaxial stretching. The separator's microstructure produced by the uniaxial stretching process is elongated and interconnected, with good conductivity. No solvents are used during the production process, making the process environmentally friendly.
Phase 1 will be in mass production in 2022 and, when Phase 2 is finished by 2024, it will gain 600 million square metres of lithium-ion battery separators annually, which can meet the demand for 60 GWh batteries, corresponding to about 550,000 zero-emission pure electric vehicles.
Simultaneously, the separator allows the transport of ionic charge carriers that are needed to close the circuit during the passage of current in an electrochemical cell. To fulfill these functions, separator film in lithium-ion batteries must meet a number of requirements:
