Market Overview

An automotive lead acid battery separator is a nonconductive, porous substance that is positioned between the battery's positive and negative plates. India is one of the largest automobile markets in the world, driving demand for passenger cars, commercial vehicles, and two wheelers. As automobile demand has increased, SLI batteries are also becoming more in demand. Separators play a key role in defining the efficiency, reliability, and safety associated with SLI batteries, which are critical components in ICE vehicles. According to the Society of Indian Automobile Manufacturers, overall automobile production in India for FY 2022-2023 is 28.43 million units, a growth of 7.89% compared to the FY 2019-2020 period and 9.59% compared to the FY 2022-2023 period. Auto manufacturing is poised for further growth as major companies launch significant programs and projects to meet the growing country's demand for vehicles. For instance, in February 2024, Toyota Kirloskar Motor launched its Awesome New Car Delivery Solution. The project aims to streamline vehicle logistics by eliminating the need for dealer staff to drive new vehicles to delivery locations. The program provides consumers access to 130 dealer locations in 26 states around the country in the first phase of the project to respond to regional demand for vehicles.

Governments globally are encouraging the automotive lead-acid battery separator market to expand by enforcing recycling laws, environmental restrictions, and policies promoting sustainable materials. Extended Producer Responsibility, for instance, was adopted by India's Battery Waste Management Rules (2022) and requires producers to collect and recover spent batteries. This increases demand for long-lasting and recyclable separators.
