Industry Trends and Drivers:
- Growing Adoption of Electric Vehicles (EVs):
The growing global trend of vehicle electrification that is driving electric vehicle sales is further pushing the lithium-ion battery separator market. With the shift to EVs, the demand for high-performance energy storage elements is rising. Hence, separators required for battery safety as well as subsequent efficiency are not made from metals. They protect against shorting and facilitate the flow of ions in the device. Also countries are promoting EVs through relaxations, regulatory emission standards, and improved charging infrastructure. This push drives the need for next-generation battery systems. Separators contribute to the extension of battery life, safety, as well as improved performance of batteries. For this reason, innovations such as improved thermal stability and durability of separators are likely to drive the market forward.
- Rising Demand for Consumer Electronics:
Currently the lithium-ion battery is employed in smartphones, laptops, and wearables. Such devices are in great demand because the developed cities and high income standards of people. They pointed out that this trend is helping to increase the market. The separators are of importance to safety, reliability, and energy of lithium-ion batteries. Since the size of the new devices shrinks while their capabilities grow, the battery performance matters. Separators assist to maintain the efficiency of battery while at the same time, minimize their size and mass. Consumers desire for more battery longevity, faster recharge time, and increased overall safety. As this demand continues to grow, the have further exposed the need for improved separator technologies.
- Energy Storage Systems (ESS) Expansion:
Solar and wind power have increased the need for energy storage systems or ESS. Lithium-ion battery technology is generally preferred for ESS use due to its compatibility of energy, efficiency, and flexibility. The most attention in these systems is paid to battery separators. They avoid the formation of short circuits and ensure that the electrodes are separated. In addition, the expansion of clean energy investments and the upgrade of the grid to reduce CO2 emissions are important factors for the market. This has led to an increase in the demand for lithium-ion battery separators. These separators have to accommodate larger systems and need to withstand more harsh operating conditions as well as provide longevity, high performance, and safety.
