Though it may have a stinky reputation, sulfur could set EVs on the path to total ICE replacement if energy-dense, low-weight lithium-sulfur batteries become the norm. British-based OXIS Energy is banking its business on it. If American clean energy industries are to take full advantage of the emerging lithium-sulfur (Li-S) battery chemistry, they just may… Read more »

Consumer Reports: Tesla Model S is the best car since 2007 (VIDEO)
Tired of hearing about a certain California carmaker? Well, sorry. Tesla’s name is all over the press this week, from gushers about stock market success to sour-grapes hit pieces about ZEV credits to tantalizing hints of next-gen batteries and self-driving sedans. However, this is the most important news of all for a prospective Model S buyer: Consumer… Read more »
Mouse Tesla offers to remove thorn from Lion Boeing’s paw
Elon Musk, the entrepreneurial force behind Tesla Motors and SpaceX, who surely knows a thing or two about lithium-ion batteries, has offered unspecified aid to aviation giant Boeing, whose flagship 787 Dreamliner remains grounded after a pair of battery-related incidents. “Desire to help Boeing is real & am corresponding w 787 chief engineer,” Musk tweeted… Read more »
Tests confirm Envia Systems’ lithium-ion battery breakthrough
Envia Systems announced today that a test sponsored by ARPA-E has verified the company’s impressive claims for its new battery cells. Envia’s prototype juice boxes have achieved an energy density of 400 Watt-hours/kilogram – the highest ever recorded for a rechargeable lithium-ion cell. We’ll leave the hyperbole to the marketing folks, and settle for a… Read more »
Book review: “Bottled Lightning: Superbatteries, Electric Cars, and the New Lithium Economy”
Seth Fletcher, in the epilogue to his book about the burgeoning lithium economy, asks: “Will this last? Is this…the beginning of something enduring – a new era for transportation, energy and American high tech manufacturing? Or will it turn out to be a portrait of another false start, an anomalous couple of years in which,… Read more »
Tesla Roadster speeds silently into the sunset
As planned, the last Roadster rolled off the production line at Tesla Motors this month. The Silicon Valley startup built 2,600 of the all-electric two-seaters, installing a lithium-ion battery pack and electric motor into a glider manufactured by Lotus. As reported by Autoblog, Tesla tricked out the last few units as a Final Edition – bright… Read more »
Panasonic to supply battery cells for Tesla’s Model S
Two major EV pioneers have announced another chapter in their partnership, an agreement under which Panasonic will supply Tesla Motors with lithium-ion battery cells for Tesla’s new Model S. Panasonic is a major investor in Tesla, and the two companies have worked closely together to develop an EV-optimized battery cell based on nickel-type cathode technology…. Read more »
Practical aspects of off-grid EV charging
The holy grail for many EV owners is to obtain all of the energy needed for recharging from renewable energy sources, and while that’s difficult to justify on a purely economic basis if grid power is available, for those living off-grid it will be all but necessary to rely on renewable energy sources, as in… Read more »
Aqua Metals is building a more sustainable battery recycling ecosystem
Q&A with Aqua Metals execs Steve Cotton and David Regan Regardless of the claims made in Facebook memes, Li-ion batteries are eminently recyclable, and current recycling methods cause far less environmental damage than the well-documented depredations of the petroleum industry. However, as sustainability is central to the mission of the EV industry, we need to… Read more »
Trade group asks administration to reinstate tariffs on Chinese graphite, critical material for EV batteries
The North American Graphite Alliance (NAGA), which represents US and Canadian producers of battery-grade graphite, has submitted a request to US Trade Representative Katherine Tai to reinstate Section 301 tariffs on three graphite products from China. The group also commissioned a market report from Oxford Economics that explains the rationale behind reinstating the tariffs, and… Read more »
