Scientists and technology companies are constantly seeking ways to improve battery life and efficiency. Now, for the first time using a water-based solution, researchers at the University of Missouri have created a long-lasting and more efficient nuclear battery that could be used for many applications such as a reliable energy source in automobiles and also in complicated applications such as space flight.
“Betavoltaics, a battery technology that generates power from radiation, has been studied as an energy source since the 1950s,” said Jae W. Kwon, an associate professor of electrical and computer engineering and nuclear engineering in the College of Engineering at MU. “Controlled nuclear technologies are not inherently dangerous. We already have many commercial uses of nuclear technologies in our lives including fire detectors in bedrooms and emergency exit signs in buildings.”
The battery uses a radioactive isotope called strontium-90 that boosts electrochemcial energy in a water-based solution. A nanostructured titanium dioxide electrode (the common element found in sunscreens and UV blockers) with a platinum coating collects and effectively converts energy into electrons.
“Water acts as a buffer and surface plasmons created in the device turned out to be very useful in increasing its efficiency,” Kwon said. “The ionic solution is not easily frozen at very low temperatures and could work in a wide variety of applications including car batteries and, if packaged properly, perhaps spacecraft.”
The research, “Plasmon-assisted radiolytic energy conversion in aqueous solutions,” was conducted by Kwon’s research group at MU, and was published in Nature.
Nissan boss Carlos Ghosn is preparing to cut battery manufacturing, people familiar with the matter said, in a new reversal on electric cars that has reopened deep divisions with alliance partner Renault.
The plan, which faces stiff resistance within the Japanese carmaker, would see U.S. and British production phased out and a reduced output of next-generation batteries concentrated at its domestic plant, two alliance sources told Reuters.
In what may also prove a politically sensitive blow to Japan Inc., Nissan would follow Renault by taking cheaper batteries from South Korea's LG Chem for some future vehicles, including models made in China.
"We set out to be a leader in battery manufacturing but it turned out to be less competitive than we'd wanted," said one executive on condition of anonymity. "We're still between six months and a year behind LG in price-performance terms."
A decision on the Nissan battery plants in Sunderland, England, and Smyrna, Tennessee, is due next month, the sources said, following a tense procurement review with 43.4 percent shareholder Renault, the smaller but senior partner in their 15-year-old alliance.
"Renault would clearly prefer to go further down the LG sourcing route, and the Nissan engineers would obviously prefer to stay in-house," another insider said. "The write-off costs are potentially huge."
Renault-Nissan "remains 100-percent committed to its industry-leading electric vehicle programme" and has no plans to write down battery investments, spokeswoman Rachel Konrad said.
"We have not taken any decision whatsoever to modify battery sourcing allocation," Konrad said, adding that the alliance "does not confirm or deny procurement reviews."
But Nissan is already negotiating with manufacturing partner NEC Corp. on the shift to dual sourcing, with Chief Executive Ghosn's backing, the sources said. Nissan currently makes all its own electric car batteries.
One option being explored would see LG, which supplies some Renault models, invest in its own battery production at one of the overseas Nissan plants as the carmaker halts operations at the sites.
The alliance is also in talks with LG on a deal to supply batteries for future Renault and Nissan electric models in China, one of the sources added.
NEC and LG declined to comment.
Under Ghosn, who heads both companies, Renault-Nissan bet more on electric cars than any mainstream competitor, pledging in 2009 to invest 4 billion euros ($5.2 billion) to build models including the Nissan Leaf compact and as many as 500,000 batteries per year to power them.
Nissan and NEC invested 23 billion yen ($215 million) in their Zama, Japan battery plant and electrode manufacturing, backed by government aid. U.S. and British taxpayers also helped with the $1 billion invested in Tennessee and 210 million pounds ($341 million) in Sunderland.
The alliance has begun a belated push into faster-selling hybrids, combining electric and combustion-engine propulsion. Upscale electric rivals such as Tesla's Model S meanwhile hog the limelight, backed by big investments in newer, cheaper battery technologies.
INTERNAL RIVALRIES
Ghosn dropped extra battery sites planned for both alliance carmakers, leaving Nissan with the entire production capacity of 220,000 power packs through the NEC joint venture, AESC.
But that still far exceeds the 67,000 electric cars Renault-Nissan sold last year, and even the 176,000 registered to date. A pledge to reach 1.5 million by 2016 has been scrapped.
The coming hybrids will fill some of the excess plant capacity, although they use fewer power cells per vehicle. An all-electric Tesla rival is still planned for Nissan's premium Infiniti brand in 2018 with batteries as big as 60 kilowatt-hours (kWh), more than twice the energy capacity of the Leaf, which is due for replacement the previous year.
Nissan is seeking to unwind a ruinous NEC contract that requires it to purchase electrodes for the full capacity of 220,000 Leaf-sized 24 kWh batteries regardless of actual sales, sources said. The joint venture partner's consent is also needed to bring LG production or other activities onto the Tennessee or Sunderland sites, which together employ 500 workers.
The financial hit for Nissan "will depend on what else we can do with the plants", with heavy charges likely if both are closed, one manager added.
The Nissan procurement shift could still be thwarted by capacity-cutting costs including repayment of U.S. and British government support. Next-generation battery manufacturing at Zama would also likely need fresh Japanese aid to compete with LG and its subsidies from Seoul, sources said.
Navigating the battery backtrack is a key test for CEO Ghosn as he demands closer Renault-Nissan integration from executives mandated to pursue savings across the alliance.
For Nissan, the plant cuts would be a partial retreat from the automotive battery market - expected to top $20 billion by 2020 - just as California-based Tesla builds its $5 billion "Gigafactory" with Panasonic in Nevada.
Japanese engineers are still smarting from Renault's 2010 move to drop Nissan batteries and purchase LG for its flagship Zoe model, worsening the overcapacity problem.
"It was a 15-20 percent cost gap," said one of the people involved in the Renault decision. "In purchasing, 3-4 percent is usually enough to choose a partner for."
Today's Nissan batteries come in at $270 per kWh, based on replacement prices thought to be below cost, according to consulting firm AlixPartners. The true manufacturing cost is believed to be over $300, inflated by the amortisation of unused plant capacity and the burdensome electrodes deal.
The next generation will have lithium nickel manganese cobalt oxide (NMC) cathodes, as used by LG, rather than the current lithium manganese oxide (LMO) chemistry. The alliance cost target is $200/kWh, whether made or bought, sources said.
With a clean slate and sufficient volume, Nissan engineers insist, their next generation of batteries could be competitive on price as well as keeping crucial know-how at the company.
"When you're developing cutting-edge technology, the best way to know about that technology is to build it in-house," said one. "That's what Tesla is doing."
Many of the past missteps can be traced to internal rivalries of the kind Ghosn is only now moving to stamp out.
Former Nissan second-in-command Carlos Tavares, racing to beat the Renault Zoe to market, cut Leaf development by a year and skipped a critical battery redesign, according to alliance veterans. Nissan later cut prices, settled a class action and offered retroactive warranties to answer customer concerns about battery deterioration. Tavares now heads PSA Peugeot Citroen.
His Renault archrival at the time, Patrick Pelata, signed a confidentiality deal with LG that meant Nissan battery engineers never even knew what they were up against.
Against that backdrop, the atmosphere may be charged when Nissan engineering boss Hideyuki Sakamoto puts final arguments against the outsourcing plan in a presentation to Ghosn as soon as this week.
But the CEO's mind may be all but made up.
"We're in the process of opening up battery sourcing to a range of suppliers," Ghosn said last week when asked whether Renault could buy batteries from France's Bolloré.
In future some batteries will likely be outsourced "within the framework of alliance procurement", he added. "What's important to us is that electric car performance fully meets customer expectations."
A partnership of Battery Electric Vehicle (BEV) manufacturers have joined forces through the European Union's TEN-T programme to create a multi-standard and inter-operable charging network through the United Kingdom and Ireland.
As well as helping to finance the scheme, the consortium is providing other members of the project with the benefit of its extensive experience in the BEV field.
This is the first time leading BEV companies Renault, Nissan, BMW and Volkswagen have united to accelerate the growth of EV charging infrastructure, seen as a key enabler towards making zero-emission mobility a market reality. The project, managed by Zero Carbon Futures in North East England also draws on the network expertise of ESB, one of Ireland's foremost energy company and leader of a previous TEN-T project completed this summer, and Newcastle University.
When complete, the UK Rapid Charge Network (RCN) will comprise more than 70 multi standard rapid chargers covering some 1,100km of major trunk routes and providing EV-friendly links to five seaports and five international airports.
Running on two priority road axis on the mainland, the UK RCN will link major ports and cities including Stranraer, Liverpool, Holyhead, Birmingham, Felixstowe, Leeds and Kingston upon Hull while there will also be networks embracing Dublin, Ireland and Belfast, Northern Ireland.
Significantly, the rapid chargers are the latest state-of-the-art multi-standard units and are compatible with cars using 44kW CCS, 44kW CHAdeMO or 43kW AC systems. This will ensure that EV drivers travelling in the UK can undertake long journeys secure in the knowledge that they will never be far from a rapid charger.
Ten rapid chargers have been already installed with a further 28 sites soon to be commissioned.
The UK RCN is part of the European Union-financed Trans European Transport Network (TEN-T) and represents a substantial partnership investment of €7,358,000, half of which is being funded by the EU.
A significant portion of the BEV manufacturers' contribution to the overall costs will be used to fund a research program, led by Newcastle University. This will aim to confirm the benefits of such an advanced inter-operable EV rapid charging network.
Strategic information gathered from users, including customer charging behaviour and changes in mobility patterns, will help plan the roll-out future rapid charging infrastructure in member states across Europe.
During a recent trip to Japan, Tesla CEO Elon Musk says his company and Toyota could team on another “significant” joint project in two or three years, and at higher volumes than the soon-to-end RAV4 program.
Musk’s comments came just four months after Tesla Motors Inc. announced that the agreement to supply battery packs for the electric Toyota crossover would finish this year with sales around 2,500.
Musk said there were no concrete plans for a new vehicle with Toyota but dangled the possibility of a bigger project soon.
“I think that if you look out maybe two or three years from now, that I would not be surprised if there is a significant deal with Toyota,” Musk said today at a ceremony to deliver the first Tesla Model S sedans to customers in Japan.
“My best guess is that it would probably be something significant, maybe on a much higher volume level,” he said.
Toyota Motor Corp., which owns 2.4 percent of Tesla, said in May 2012 it envisioned building around 2,500 RAV4 EVs over three years. When the partners announced in May that the program would wrap this year, they were noncommittal about future projects.
The Japanese and American companies have since sparred over alternative visions for tomorrow’s alternative drivetrains.
Toyota has channeled its focus into hydrogen fuel cells, while dismissing EVs as impractical and impossibly short-ranged. Meanwhile, Tesla has beat the drum for batteries, while deriding cars powered by hydrogen stacks as “fool cells.”
Toyota spokesman Dion Corbett said the world’s biggest carmaker had “nothing to say” in response to Musk’s latest overture.
Toyota sold 2,130 RAV4 EVs through August. The company expects to sell the rest of the planned 2,500 by year’s end.
After those are delivered, Toyota will have neither a single EV nameplate in its lineup nor public plans to add one.
Musk was not expected to meet with Toyota officials during his visit to Japan. While in Tokyo, he handed over the keys to nine new Model S sedans on the 52nd-floor observatory of Roppongi Hills Mori Tower, one of the tallest buildings in town.
“We love working with Toyota,” he said. “We have a huge amount of respect for them as a company and certainly much to learn.”
