EU-funded researchers in the LISSEN (Lithium Sulfur Superbattery Exploiting Nanotechnology) project have developed a new lithium-sulfur battery that uses lithiated silicon as the anode and a nanostructured sulfur-carbon composite as the cathode. The team says its battery offers an energy density at least three times higher than that of current lithium battery technology, as well… Read more »

Slow sales for Tesla in Germany. Are more EV incentives on the way? (UPDATED)
Last month’s Frankfurt auto show was positively crackling with EV news, as Audi, BMW and Porsche presented concept EVs, Mitsubishi showed its 2016 Outlander PHEV, and several suppliers touted tech advances. However, the comparatively low-key presence of electric trendsetter Tesla – which was showing red, white and blue Model S but no Model X –… Read more »
BASF expands range of high-voltage plastics for color-coded connectors
BASF is expanding its range of engineering plastics for electric and hybrid vehicles. Tailor-made Ultramid and Ultradur materials are now available for equipping vehicle-interior and -exterior high-voltage plug-in connectors with precisely fitting characteristics. Plastics used for connectors in vehicles must meet stringent requirements regarding flame retardancy, color stability and electrical isolation. High-voltage connectors are typically… Read more »
Tesla tweaks its battery chemistry: a closer look at silicon anode development
In mid-July, Tesla Motors made a trio of Model S update announcements. The new options included a 70 kWh rear-wheel-drive base model, an upgrade for the high-end battery pack from 85 to 90 kWh (providing about a 6% increase in range), and Ludicrous mode, which offers a 10% improvement in the car’s 0 to 60… Read more »
Bosch: Our new EV heat pump system can increase range by up to 25%
Heating and cooling an EV presents a special challenge, as battery power must be used for climate control, which can significantly reduce range. Automakers and researchers around the world are working on a range of alternative solutions. Nissan and Volkswagen both use heat pumps in their EVs. The JOSPEL project, a consortium of organizations from… Read more »
2016 Cadillacs to use Maxwell ultracapacitors in start-stop system
Start-stop vehicles (SSVs, if you will) occupy the bottom rung of the electrification ladder, and they’re growing in importance as global OEMs search for ways to meet tightening emissions standards (anything other than selling EVs, it sometimes seems). Over 40 percent of new cars sold in Europe already incorporate start-stop technology. A battery-based start-stop system… Read more »
Another Chinese-backed startup announces plans for an electric supercar
New EV companies are cropping up like dendrites on a lithium metal anode. The latest startup to emerge from stealth mode is called NextEV. Like many of the current crop (see Faraday Future, Atieva, Fisker, Leshi), NextEV is backed by Chinese investors, and is not affiliated with a traditional automaker, although it has recruited execs… Read more »
Mercedes confirms plans for high-end EV
Daimler is accelerating into the electric future. Last year the company spent about half of its 5-billion-euro R&D budget on electrification and other emission-reducing technologies, and announced that it would introduce 10 new plug-ins by 2017. The Mercedes S550 Plug-In Hybrid, the group’s third model with a cord, went on sale in the US in… Read more »
Efficient Drivetrains builds fleet of plug-in trucks for Port of Shanghai
Efficient Drivetrains, Inc. (EDI) has partnered with Shaanxi Automotive to build a fleet of plug-in hybrid trucks to the Port of Shanghai. Shaanxi said it expects to provide up to 200 of the PHEVs in 2016. The two companies are already working together on plug-in natural gas hybrid city buses. Shaanxi built a prototype bus… Read more »
Solid-state battery innovator Seeo acquired by Bosch
Giant German automotive supplier Bosch has announced that it will acquire the Silicon Valley startup Seeo, a pioneer in solid-state battery technology. Seeo’s cell design combines a solid lithium metal anode with a conventional porous lithium iron phosphate cathode and Seeo’s proprietary DryLite solid polymer electrolyte. Seeo says its cells achieve specific energy of around… Read more »
