How better batteries are accelerating autonomy

If the robotics industry had a celebrity, it would be SpotMini of Boston Dynamics. At the Robotics Summit & Showcase, produced by The Robot Report and WTWH Media, the mechanical dog strutted onto the floor of the Westin Hotel trailed by hundreds of flickering iPhones.

Boston Dynamics founder and CEO Marc Raibert first unveiled his metal menagerie almost a decade ago with a video of Big Dog. Today, SpotMini is the fulfillment of his mission in a sleeker, smarter, and environmentally-friendlier robo-canine package than its gas-burning ancestor.

Since the early 1990s, machines have relied on rechargeable lithium ion batteries for power. However, these storage cells (inside most cell phones, and now SpotMini) are dangerously combustable, easily degradable, and very expensive. One of the best examples of the instability of lithium ion is the Samsung Note 7 handset recall after exploding units caused havoc to consumers. The design flaw ended up costing Samsung $6.2 billion, and even prompted the Federal Aviation Administration (FAA) to issue an advisement after panic flyers saw cellphones overheat. Exploding batteries are not limited to Samsung, but across the entire lithium ion appliance ecosystem, including e-cigarettes, hoverboards, toys, and electric vehicles.

While Raibert was showing off SpotMini, across the river in Woburn, Mass. Ionic Materials was opening its new 30,000 square-foot lab. The hot startup grabbed headlines months ago with a $65 million venture capital investment from the new Renault-Nissan-Mitsubishi Alliance, Total Energy Ventures, and Sun Microsystems co-founder Bill Joy.

But the real story is Ionic Materials’ revolutionary solid-state lithium battery technology that is cheaper, less flammable and longer lasting. The technology came out of the research of Dr. Michael Zimmerman of Tufts University that was originally aimed at improving the performance of existing lithium ion batteries. Unlike lithium ion batteries that contain flammable liquid electrolyte, Zimmerman’s invention deploys a solid polymer electrolyte preventing short-circuiting. Ionic’s plastic electrolyte not only prevents explosive gases from escaping, but enables the composition battery to be constructed with higher energy density materials, such as pure lithium anodes.

Zimmerman first unveiled his innovation on PBS NOVA last year, whereby the famed host David Pogue tested it by poking the solid-state lithium cell with a screwdriver and scissors. Typically, such stress would immediately cause liquid electrolyte to explode, but Zimmerman’s battery did not even heat up and kept working. Pogue then noted, “If you can use lithium metal rather than lithium ions, you get five to ten times the energy density. That means ten days on a charge instead of one day on a charge, a thousand miles on a charge of your car instead of 200 miles.”

The promise of Ionic’s technology helps alleviate “range anxiety,” the fear of running out of charge without a power source nearby. The future of robots, and especially autonomous vehicles, relies heavily on investments in infrastructure to rival oil. Today, it takes 75 minutes to fully recharge the 7,104 lithium ion batteries inside a Tesla at one of of its 5,000 supercharging stations, compared to 15 minutes at the pump at more than 165,000 gas stations throughout America. Realizing the shortcomings of switching to electric, Sweden is making country-wide investments to accelerate adoption. Last month, Stockholm opened the first stretch of roadway capable of simultaneously charging vehicles while driving.

Markus Fischer, spokesperson for state-owned energy company Vattenfall, describes “Such roads will allow (electric vehicles) to move long distances without big, costly and heavy batteries. The investment cost per kilometer is estimated to be less than that of using overhead lines, as is the impact on the landscape.” Currently, only 1.2 miles of electric rail has been laid, but it is already working with trucks making deliveries to the airport. Gunnar Ashland, CEO of Elways the maker of the road’s electric rail, boasted, “The technology offers infinite range — range anxiety disappears. Electrified roads will allow smaller batteries and can make electric cars even cheaper than fossil fuel ones.”

At the Robotics Summit, I spoke with Brenden Smerbeck of electric battery provider Acumentrics about the Swedish technology. Smerbeck explained that most conductive charging platforms similar to Elways speed the degradation of lithium ion batteries. Israeli startup Phinergy offers an alternative to lithium for electric vehicles with their proprietary aluminum batteries that produce energy through a reaction between oxygen and aluminum using water.

A few years ago, Phinergy powered a Renault car for over a thousand kilometers with just tap water. Now the company has partnered with Chinese-based Yunnan Aluminum to begin manufacturing batteries to meet China’s growing electric automobile market. According to the press release last month the joint venture “will introduce the world’s leading aluminum-air battery technology, relying on [Yunnan Aluminium’s] green and clean water and aluminum resources.” The statement further detailed that the initial annual output will be 2,500 units. Phinergy’s website promotes wider uses cases, including industrial robots and other unmanned systems.

China has been leading the world in alternative energy development. Last year, Pittsburgh-based Aquion was acquired out of bankruptcy for $9.16 million by Juline-Titans, an affiliate of China Titans Energy Technology Group. Aquion, a once high-flying startup that raised more than $190 million from such notable investors as Bill Gates, Kleiner Perkins Caufield & Byers, and Nick and Joby Pritzker, is now in the process of moving its operations to Asia. Similar to Phinergy, Aquion utilizes the most renewable of resources, water. Their patented “Aqueous Hybrid Ion” technology is able to create clean energy using sea water. However, it comes at a cost of weight: unlike lithium batteries that are light enough to fit in one’s pocket, salt-water fuel cells are considerably heavier. The company’s products are uniquely positioned to be utilized for future power grids, with the promise of weaning the world off fossil fuels.

Today, fewer than 5 percent of lithium-ion batteries are recycled. The environmental costs could not be higher with dangerous toxic gases leaking from old batteries. Rising battery demand is also leading to a variety of unintended consequences, such as depleting the world’s natural resources of lithium and cobalt and increased water pollution from mineral extraction. While turning the tides of climate change depends greatly on ending the global dependency on oil, replacing it with a more green alternative is crucial.

Promising inventions are not only developing new energy paradigms, but recycling old ones in innovative ways. British startup Aceleron is reusing dead electric car batteries for home energy storage. In the words of Amrit Chandan of Aceleron, “It takes so much energy to extract these materials from the ground. If we don’t re-use them we could be making our environmental problems worse. There’s going to be a storm of electric vehicle batteries that will reach the end of their life in a few years, and we’re positioning ourselves to be ready for it.”

Climate change and unmanned systems will be discussed in greater detail at the next RobotLab on “The Politics Of Automation,” June 13th @ 6pm in NYC, with Democratic Presidential Candidate Andrew Yang and New York State Assemblyman Clyde Vanel.
