COVID-19 Impact: Market Growth Restrained During Pandemic Due To Reduced Demand And Operational Shutdowns

The Global COVID-19 pandemic has been unprecedented and staggering, with the market experiencing lower-than-anticipated demand across all regions compared to pre-pandemic levels. The sudden market growth reflected by the rise in CAGR is attributable to market’s growth and demand returning to pre-pandemic levels.

Stringent measures that were taken globally as a result of the COVID-19 outbreak impacted the Li-Ion Battery Separator Market to a significant extent because the competencies of organizations had to be adjusted due to the shutdown of operations and challenges in the extended supply chain. The COVID restrictions and lockdowns hampered the consumer buying of electronics and electric vehicles, which are some of the main consumers of Li-ion batteries. Such a decline resulted in a reduction of orders and delayed projects of Li-ion battery separators and, thus, affected market development in the pandemic period.

LATEST TRENDS

LI-ION BATTERY SEPARATORS MARKET SEGMENTATION

By Type

Based on type the market can be categorized into Wet Method & Dry Method.

• Wet Method: The wet method signifies the use of solvent-based processes in the production of separators in the Li-Ion Battery Separator Market. This method generally comprises coating, solvent evaporation, and drying to provide the separator film. Wet method separators represent high porosity and uniformity, which are very important for increasing the performance of the battery and its safety level.

• Dry Method: The dry process in the Li-Ion Battery Separator Market does not use any solvent-based processes to create separators. The process involves the melt extrusion or dry casting processes of polymers by converting them into separator films. Dry-method separators are preferred by manufacturers for their low energy consumption, minimal pollution, and efficiency in controlling the thinness of structures and porosity.

By Application

Based on application the market can be categorized into Consumer Electronics, Power Vehicle & Electric Power Storage.

• Consumer Electronics: In the Li-Ion Battery Separator Market, the consumer electronics segment requires separators that are high-performing, reliable, and safe. These separators facilitate energy storage and the processes of discharging electronics like smartphones, laptops, and tablets. Portable electronics are powering up more and more, which increases the demand for superior separators for prolonged battery life and faster charging.
