RE:Bloomberg.com todayIn the race to bring large-scale rechargeable batteries to the masses, theres Tesla Motors Inc., Panasonic Corp. and Samsung Electronics Co. Then theres tiny Electrovaya Inc. The Canadian manufacturer of lithium-ion batteries, run by an adjunct professor of electrochemistry at the University of Toronto, has generated just C$47 million ($36 million) in revenue in the last five years. Yet investors are betting it can grab a slice of a market thats estimated by Bloomberg New Energy Finance to be worth at least $250 billion by 2040. Shares of Mississauga, Ontario-based Electrovaya have risen almost five-fold to a market value of C$297 million ($228 million) over the past 12 months, outpacing the WilderHill New Energy Global Innovation Index and its top performer SMA Solar Technology AG, which doubled its returns. Tesla, which shipped its first commercial Powerwall this year, is down 20 percent. Lithium-ion batteries are one of the latest ways of storing energy from solar, wind and other sources and are used to power everything from cars to household appliances. Bloomberg New Energy Finance estimated in a study released in June that utility-scale batteries will be as widespread in 12 years as rooftop solar panels are now. Recent transactions by Electrovaya support the companys meteoric rise, said Carter Driscoll, analyst at FBR Capital Markets & Co. The company signed three deals worth almost C$400 million in the past month alone and expects to begin delivering on those contracts by the fourth quarter, according to a statement. Intriguing Deals Whats helping the company is that they are focusing in the right areas of the renewable energy market, Driscoll said in a phone interview from New York. Electrovayas deals were signed with manufacturers that give them high margins, he said. They include a C$288 million three-year contract with a European manufacturer of residential-energy storage units, a C$16 million deal for electric buses, and a C$80 million contract to supply a U.S. firm with batteries and systems. Electrovaya hasnt identified the companies. The sudden size of their recent deals is intriguing and points to potential that they really may have special technology, Driscoll said. Next GE? Electrovayas proprietary technology, protected by about 400 patents, is what Chief Executive Officer Sankar Das Gupta says gives the company an edge. Its flexible ceramic separator is capable of withstanding unusually high temperatures, guarding against the kind of fire that has tripped up other manufacturers, he says. The companys solvent-free production process is also easier on the environment and the batteries provide nearly double the life cycle of competitors, according to Gupta. The CEO forecasts C$200 million in revenue in 2017 and anticipates more deals. Gupta, who owns 54 percent of the company according to data compiled by Bloomberg, says he has no plans to be bought out, despite receiving some interest. We dont want to be a part of anyone, Gupta, 65, said in an interview at Bloombergs Toronto offices. Were hoping to become the next General Electric. Taking on goliaths like Tesla and Panasonic, which are jointly building a $5 billion lithium-ion gigafactory in Nevada, is no easy task, Driscoll said. A representative for Tesla said the company declined to comment on Electrovaya.

It purchased the largest lithium-ion battery manufacturing plant in Europe from Daimler AG for a fraction of its tangible assets last year after the automaker decided to quit the business. Electrovaya got the plant by offering a cost-free chance to transfer an asset that had become inoperable amid Germanys tougher environmental regulations, while also keeping on its employees, Gupta said. Most importantly, the deal included the factorys proprietary ceramic separator technology. Fires have been a big problem for lithium-ion batteries, grounding Boeing Co.s 787 Dreamliners for three months in 2013, before the company redesigned them. Samsung, which says it holds the largest market share for batteries, also uses ceramic separators, a Samsung representative said in an e-mail. Panasonic declined to comment. Way Ahead With the combined German and Electrovaya technology, we think we are way, way ahead of the Panasonics and Samsungs, Gupta said. The only comparable technology in the world, he said, may be Polypore International Inc.s lithium-ion separator. That company was acquired by Japans Asahi Kasei Corp. for $3.2 billion last year. Electrovayas new factory can generate as much as C$550 million in revenue, according to a November statement. If production surpasses that limit, Gupta said hell look at acquiring similarly distressed targets in China and Japan. Electrovayas main issue is working capital, the CEO said. For every C$200 million in revenue, we would need about C$40 million in working capital. We are looking at Canadian and German banks for loans, but they are very risk-adverse right now, he said. He hopes that support from Export Development Canada will help convince lenders to open up. Execution is another risk to Electrovayas long-term success, Driscoll wrote in a note to clients. The infant energy-storage market may also not grow as expected, he said. Regardless, the company remains one of the best public upside plays on energy equipment, he said in the interview, setting the target price at C$3.25 per share. Up until six months ago, no one paid attention to some small, unknown Canadian company, Gupta said. But in the last couple of weeks, a lot of the majors are now noticing us.
