Company profile

researched Aug 2026

Electroflow Technologies Inc. is a critical-materials company focused on producing lithium and battery materials domestically in the United States from brine resources. The company's stated aim is to extract lithium from dilute brines - those below roughly 200 ppm lithium concentration, which fall outside the range addressed by incumbent direct lithium extraction approaches - and it states that doing so would unlock about 75% of the lithium stored in US brines. The company frames brine-based extraction as an alternative to conventional mining ("brines over mines"), with goals of minimizing water and hazardous chemical use and shortening supply chains so that sourced lithium does not travel thousands of miles.

The company positions its work against a conventional brine-to-LFP route that it describes as a ten-step process with high lithium losses and large water and chemical consumption. Its staff spans electrochemistry, electrode fabrication, cathode synthesis, chemical, mechanical, controls and facilities engineering roles, alongside interns, indicating in-house process and hardware development. Electroflow is led by co-founders Eric McShane (CEO) and Evan Gardner (CTO) and is based at 1162 Cherry Ave, San Bruno, California.

Full profile — market position, technology, go-to-market, geography

Market position

The company frames its addressable opportunity around North American brines, which it states contain enough lithium to produce over 300 million electric vehicles while remaining largely untapped, and around the dilute (sub-200 ppm) fraction of those resources that it says incumbent direct lithium extraction technology does not reach.

Technology

Electroflow's approach targets lithium extraction from dilute brines, which the company defines as brines containing under 200 ppm lithium, a segment it contrasts with incumbent direct lithium extraction technology aimed at brines above 200 ppm. The company describes the traditional brine-to-LFP pathway as requiring ten steps, a multistep process associated with high lithium losses and large consumption of water and chemicals, and positions its own technology as reducing water and hazardous chemical use. Internal engineering functions include electrochemistry, electrode fabrication, cathode synthesis, and controls and mechanical engineering, consistent with an electrochemical extraction and materials-processing development effort.

Go-to-market

The company recruits through LinkedIn job postings, references partners on its website, and directs business inquiries to a general company email address.

The company orients its output toward battery materials production in the United States, describing a brine-to-battery-materials and brine-to-LFP value chain relevant to electric vehicle and clean energy supply chains.

Geography

Headquartered at 1162 Cherry Ave, San Bruno, California, with a resource focus on brine deposits in North America and an emphasis on domestic US lithium production.
