ENTEK

Manufactures battery separators and extrusion solutions

Overview

ENTEK makes battery separators and extrusion equipment and services for energy storage and manufacturing customers worldwide. It focuses on lead-acid and lithium-ion separators, plus extruders and engineering services, all designed and built with in-house engineering, machining, and fabrication. Its products work by enabling safe, efficient energy storage: separators sit between battery electrodes to prevent short circuits while allowing ion flow, and extruders craft the polymer films and components used in separators. ENTEK differentiates itself through its vertical integration (in-house design, machining, fabrication), global reach across six continents, and a services-driven model that combines product sales with specialized engineering and support. The company aims to deliver reliable, best-in-class equipment and solutions through continuous improvement and decades of industry experience to meet the needs of battery manufacturers and industrial customers.

Simplify's take

What believers are saying

  • DOE disbursed $77.2 million on November 7, 2026, validating project momentum.
  • ENTEK says Terre Haute will reach 1.4 billion square meters annually by 2026.
  • Its October 30, 2026 Oregon Visionary Award strengthens recruiting, customer trust, and local political support.

What critics are saying

  • Terre Haute depends on repeated DOE disbursements; any delay stalls 2027 capacity ramp.
  • The $1.5 billion buildout must execute flawlessly; cost overruns or yield failures destroy returns.
  • Asian separator incumbents still dominate supply; ENTEK's failure leaves U.S. OEMs dependent on imports.

What makes ENTEK unique

  • ENTEK remains the only U.S.-owned wet-process lithium-ion separator maker, per November 2026 filings.
  • It designs separators, extruders, and production equipment in-house, compressing development cycles.
  • Its lead-acid and lithium separator franchises diversify revenue across batteries and industrial extrusion.

One of the 2026 winners is ENTEK, an Oregon-based manufacturer recognised for its contribution to the manufacturing industry and its role in supporting the global shift towards electrification. ENTEK recognised for battery technology. Founded in Oregon in 1984, ENTEK has maintained its headquarters and cultural roots in the state while expanding into a global business. Based in Lebanon, the company has become a world leader in the production of battery separators, essential components used in almost all batteries. ENTEK's products support a wide range of vehicles and applications, including cars, lorries, electric vehicles, emergency vehicles and military equipment. Its separators are used in both lead-acid and lithium-ion batteries, featuring in almost 80% of vehicles in the US and half of all vehicle batteries worldwide. The company is continuing to expand its manufacturing operations and is currently building a large-scale lithium-ion separator factory in the US. The facility is intended to support electric vehicles and battery energy storage systems used for renewable energy and data centres. The new factory is also expected to play a critical role in developing the US lithium battery supply chain and reducing dependence on imported products. Manufacturing expertise beyond batteries. Alongside its battery separator operations, ENTEK designs and manufactures extrusion and material handling equipment. This machinery is used by its own separator plants and other manufacturers working across sectors such as plastics, recycled products, building materials, biopolymers, food and medical products. ENTEK employs approximately 500 people in Lebanon, Oregon, and has a global workforce of more than 1,200. The Oregon Visionary Award recognises the company's longstanding contribution to the state's manufacturing community, its international growth and its involvement in technologies supporting electrification and energy storage.

ENTEK's $1.5B EV plant set to bring over 600 green jobs to Indiana community. March 22, 2023 Updated: October 27, 2026 (Credit: ENTEK) "This is a great day for Terre Haute and for the state of Indiana," said Governor Eric J. Holcomb. "ENTEK's decision to locate a new, $1.5 billion battery component manufacturing facility here will have a transformational impact on the West Central Indiana community and the Hoosier economy for generations to come." Founded in 1984, ENTEK is a US-based company that specializes in manufacturing 'wet-process' lithium-ion battery separator materials. Working alongside the US Department of Energy, whose objective of achieving a sustainable and robust domestic lithium battery supply chain in America. Apart from its energy storage division, which manufactures battery separators for both lithium-ion and lead-acid batteries, ENTEK also produces equipment for the plastics industry. Additionally, the company develops high-performance materials for a wide range of energy storage and functional membrane applications. ENTEK's announcement on Tuesday comes as a welcome boost to Indiana's economy, with the new production facility expected to create over 600 hundred new jobs during the next few years. Contributing a $1.5 billion investment in the Terre Haute production facility will support Indiana's growing electric vehicle (EV) industry. The Terre Haute facility. The company plans to construct four buildings covering an area of approximately 1.4 million square feet on a 340-acre greenfield site in the Vigo County Industrial Park II. These buildings will be equipped with advanced equipment, including specialty biaxial stretching equipment supplied by Brueckner Group USA. ENTEK's new facility will manufacture battery separators, which are essential components used in the production of lithium-ion batteries, a rapidly growing industry. Additionally, the battery manufacturer will utilize equipment built at their existing manufacturing facilities in Oregon and Nevada to ensure the high-quality production of these battery separators. The US Department of Energy will provide $200 million worth of funding as part of the Bipartisan Infrastructure Law. ENTEK plans to start its Indiana operations between 2025-2027 and will break ground on the campus as soon as engineering and permitting are in hand. By 2027, ENTEK aims to supply 1.4 to 1.6 million EVs annually, highlighting its commitment to meeting the growing demand for electric vehicles. Phase 1 & 2 of the project. * Phase 1: The planned expansion will produce about 1.4 billion square meters of ceramic-coated lithium separators across operations. * Phase 2: Increase by an additional 1.8 billion square meters of battery separators produced annually. In total, the project will provide enough separators for about 3.5 million electric vehicles. Job creation. During the Phase 1 expansion, ENTEK plans to create more than 640 new jobs in Terre Haute. These new positions will have wages well above the Vigo County average. Starting in 2024, ENTEK will begin hiring for key leadership positions to facilitate the recruitment of numerous associates across various departments. Jobs, including, but not limited to, production, maintenance, electricians, human resources, accounting, IT, safety, and environmental. "It has been an incredible honor to work with Larry Keith, Kim Medford, and the ENTEK team on this extraordinary opportunity for our community," said Steve Witt, President of the Terre Haute Economic Development Corporation. "At the local level, we will do our utmost to help make ENTEK's fabulous new project a success." The Indiana Economic Development Corporation (IEDC) has approved an investment of up to $8 million in tax credits and training grants based on the company's job creation plans. Additionally, the IEDC has committed up to $405,000 in grants to support the company's innovation and manufacturing readiness. Vigo County and Duke Energy are considering additional incentives to support the project, including energy cost offsets.
