Ranges are getting longer, battery capacities are getting larger, and the pressure is on to find ways to make charging faster. Unfortunately, reducing charging time by increasing charging current can have a negative effect on battery lifetime and safety. One reason for this is a phenomenon called lithium plating. “The rate at which lithium ions… Read more »

Swiss researchers develop prototype solid-state sodium battery
Researchers from Empa, the Swiss Federal Laboratories for Materials Science and Technology, and the University of Geneva (UNIGE) have built a prototype solid-state battery based on sodium as an alternative to lithium. The scientists described their research in the journal Energy and Environmental Science. Using metallic lithium as an anode material would theoretically increase energy… Read more »
OCSiAl customers discuss battery applications of single-wall carbon nanotubes
Luxembourg-based OCSiAl recently hosted a two-day Nanoaugmented Materials Industry Summit at which some 400 industry executives and researchers from 30 countries shared their experiences of working with single-wall carbon nanotubes. OCSiAl’s TUBALL nanotubes are designed to provide manufacturers with high conductivity and increased energy density as a result of a higher percentage of active material…. Read more »
UltraCharge raises $2 million to advance its battery technology
The Israeli/Australian firm UltraCharge has raised 2.5 million Australian dollars ($1.9 million) in funding to advance the development of its battery tech. UltraCharge’s technology portfolio includes a patented anode technology from Nanyang Technology in Singapore that replaces graphite in anodes with titanium dioxide nanotube fibers. The company has also agreed to acquire the rights to… Read more »
New study: EVs emit less greenhouse gases than diesels, even in coal-heavy regions
The myth of the “long tailpipe” – the idea that, because EVs are partially powered by dirty coal, they are no cleaner than legacy vehicles – just won’t go away. In 2012, a detailed study from the Union of Concerned Scientists found that even if it were charged 100% from coal, an EV would still… Read more »
Bosch introduces new 48 V Li-ion battery for mild hybrids
Bosch has introduced a new 48-volt Li-ion battery for mild hybrids. The pack configuration is 12s1p, with 8 Ah NMC/graphite cells. Charge power is 13 kW, and discharge power is 11 kW. The package weighs less than 7 kg, and is standardized for easy integration into new vehicle models. Production is scheduled to start in… Read more »
Korean battery-makers to introduce NCM 811 cells
There’s a new battery cell in town, and everybody’s talking about its better energy density and lower costs. South Korean cell maker SK Innovation recently announced that its new NCM 811 cells would be available in December for stationary storage systems, and in the third quarter of 2018 for EVs. SK’s current cells use an… Read more »
DOE awards Saratoga Energy $1 million to commercialize its battery tech
Berkeley, California-based Saratoga Energy has won a million-dollar Phase II Small Business Innovation Research grant from the DOE to help commercialize its process for synthesizing graphite from carbon dioxide. “Graphite is an essential material in advanced lithium-ion batteries,” said Drew Reid, Saratoga Energy’s CEO. “Our process produces graphite more sustainably and affordably than traditionally-sourced graphite,… Read more »
Tesla Model 3: Will this machine kill the Oil Age?
It’s hard to overestimate the importance of the Tesla Model 3 (although the media has been doing its best). There’s no question that it’s a momentous motorcar on (at least) three levels. First, Model 3’s success is widely assumed to be an existential issue for the company – if it fails to deliver on its… Read more »
Nouveau Monde and Shinzoom form JV to market anode material
Nouveau Monde Graphite has signed a letter of intent with Chinese anode producer Hunan Zhongke Shinzoom to market Shinzoom’s anode materials to battery manufacturers in North America. The two companies will form a distribution joint venture, and if the results are satisfactory after 18 months, will evaluate the feasibility of manufacturing Shinzoom’s anode material products… Read more »
