Market Overview:

The global battery separator market was valued at USD 608 million in 2018 and is expected to register a CAGR of 6.14% during the forecast period. Separator is one of core components of secondary batteries. A secondary battery comprises a cathode, an anode, an electrolyte, and a separator. Separator’s role is to electrically insulate the cathode and anode sheets from one another in a battery to prevent short circuit. It is generally made of microporous membrane and coated with materials such as polyolefins and ceramics. When a battery gets overheated, polyolefins or ceramic coatings melts to close the micropores on the membrane and restricts the flow of lithium ion or other ions and stops the battery. Thus, separator plays a crucial role in warranting safety of secondary batteries.

Segmented Analysis

The global battery separator market has been segmented by material, battery type, application, and region.

By material, the global battery separator market has been segmented into polyethylene, polypropylene, nylon, ceramic, polyvinylidene fluoride, and others. Among these, the polyethylene and polypropylene segments collectively dominated the global market in 2018 due to large-scale use of polyolefin in the recent past. However, the ceramic coating segment is projected to grow at the highest CAGR during the forecast period.

Based on battery type, the global battery separator market has been divided into lithium-ion (Li-ion), lead acid, nickel-cadmium (Ni-Cd), nickel metal hydride, and others. The market for the lithium-ion battery is growing at a fast pace in recent days due to its superior performance efficiency. The Li-ion battery segment thus is expected to hold the largest share of the global market, in terms of both value and volume, during the forecast period.

On the basis of application, the global battery separator market has been categorized into consumer electronics, automotive, industrial, and others. The consumer electronics segment was the largest market for battery separators in 2018. However, the development and adoption of electric vehicles across the world at fast pace due to various government initiatives is expected to increase the demand for battery separators in the automotive segment during the review period.
