ORNL team demonstrates high-voltage solid-state battery with impressive cycle life

Researchers at the Oak Ridge National Laboratory have demonstrated a solid-state high-voltage (5 V) lithium battery with an extremely long cycle life (10,000 cycles) and high Coulombic efficiency (99.98%). The solid electrolyte enables the use of high-voltage cathodes and lithium anodes with minimal side reactions. The energy stored in a battery of a given size… Read more »

EU scraps official targets for EV charging stations

The European Union has dropped proposed targets for the number of public charging stations member countries must install by 2020. The EU’s new alternative fuel law, due to come into force later this month, will contain no binding rules on how many charging stations are to be deployed. The law states only that governments must… Read more »

New battery, using titanium dioxide anode, can be recharged in two minutes

The latest battery breakthrough comes from Nanyang Technological University (NTU Singapore), where researchers have developed a lithium-ion battery that they say can be recharged up to 70 per cent in only two minutes, and can endure more than 10,000 charging cycles. NTU Singapore’s scientists replaced the traditional graphite anode with a new gel material made… Read more »

EPA report: EVs are beginning to have a “measurable and meaningful impact”

The most recent edition of the EPA’s annual report Light-Duty Automotive Technology, Carbon Dioxide Emissions, and Fuel Economy Trends notes that alternative fuel vehicles (including EVs, PHEVs and CNG vehicles) are beginning to have a “measurable and meaningful impact” on the fuel economy and CO2 emissions of the country’s passenger car fleet. The EPA report,… Read more »

Tesla pre-owned vehicle program could be lucrative profit center

Tesla is developing a certified pre-owned vehicle program similar to those already offered by luxury brands such as BMW and Mercedes. “With the Model S fleet now heading toward the first cars hitting three years old, we are looking at CPO and how best to structure.” VP of Communications Simon Sproule told Automotive News. In… Read more »

Will European drivers warm to hybrids?

Hybrids, with or without plugs, are comparatively rare on European roads, but Automotive News believes that’s about to change, as EU limits on CO2 emissions become stricter, forcing Continental automakers to electrify. German and French automakers dominate the market in Europe, and diesels have long been their chosen solution, accounting for half of new-car sales… Read more »

As DC fast chargers multiply, so do standards

Public DC fast-charging stations are proliferating around the world at what some might call an alarming rate. In at least 50 countries, EV drivers can top up their batteries in the time it takes to (leisurely) enjoy a cup of tea, or whatever the local beverage may be. While automakers agree on the importance of… Read more »

Nissan CEO: We’re going to continue to make our own batteries

The EV world was shocked by recent reports that Nissan is thinking about cutting production of its proprietary battery packs in favor of sourcing packs from South Korea’s LG Chem. Speculation ran riot in the media, but facts were few. This week, the picture became clearer, as Green Car Reports asked Nissan CEO Carlos Ghosn… Read more »

New research shows how “atomic shuffling” stresses anodes and causes them to fail

Michigan Technological University researchers exhort you to take pity on “the poor lithium ion.” As it endlessly rushes from anode to cathode and back again, all kinds of chemical processes take place, eventually causing batteries to lose capacity, and possibly even overheat. Much of what goes on at the atomic scale as lithium-ion batteries are… Read more »
