The curious case of ionic liquids: Boulder Ionics/CoorsTek Specialty Chemicals Iolyte electrolytes When you think of liquids under the brand name Coors, you think of the Silver Bullet, the Banquet Beer. You certainly don’t think of high technology, unless you’re really easily impressed by cold-activated cans. However, not everyone knows that there’s another huge conglomerate under… Read more »

Snail shells inspire new battery design
Nanostructured electrodes in Li-ion batteries have several advantages, including shorter distances for charge-carrying particles to travel and a high surface area that provides more active sites for electrochemical reactions to occur. However, working with nanoscale materials is tricky – due to their tiny size, they can be hard to control and hold in place. To… Read more »
Kevlar-based nanocomposite foils dendrites for bulletproof batteries
Those doggone dendrites are a bane of battery builders. These pesky fern-like growths can form on the surfaces of anodes during cycling, reducing battery life or even causing a catastrophic short circuit – this is how the battery fires on the Boeing 787 are thought to have started. A team of researchers from the University… Read more »

Fuji Pigment develops new type of aluminum-air battery
Metal-air battery technology could offer very high energy density, and is considered a promising candidate for “beyond Li-ion” next-generation batteries. Aluminum, which is abundant and cheap, is a likely anode material. Aluminum-air batteries have a theoretical specific energy of up to 8.1 kWh/kg, second only to lithium-air batteries (13.0 kWh/kg). A pioneer in the aluminum-air… Read more »
Tesla’s batteries – past, present and future
This article is an excerpt from Tesla Motors: How Elon Musk and Company Made Electric Cars Cool, and Sparked the Next Tech Revolution by Charged Senior Editor Charles Morris. Tesla seems to make a point of doing things differently than other automakers, and its battery pack – the most critical component of any EV –… Read more »
Thin-film supercapacitors could be embedded in body panels
Researchers around the world are working on supercapacitors (aka ultracaps), whose high power density makes them a perfect complement for lithium-ion batteries. Meanwhile, a couple of visionaries at Volvo have been thinking about ways to get around the high space requirements of batteries by storing energy in a car’s body panels.

New joint venture will produce Li-ion cathode active materials
Chemicals giant BASF and metal oxide specialist Toda Kogyo have agreed to form a joint venture for Li-ion cathode active materials (CAM). The firms will combine their respective CAM businesses, intellectual property and production assets in Japan. The new venture, BASF Toda Battery Materials, will produce a broad range of cathode materials, including Nickel Cobalt… Read more »
Freudenberg Group’s new line of Li-ion battery separators
The separator is a critical component of a battery. It provides a barrier between the anode and the cathode while enabling the exchange of ionic charge carriers from one side to the other. For over 40 years, the Freudenberg Group has been producing separators for nickel-based batteries, such as the nickel-metal hydride (NiMH) cells widely… Read more »
Renault and Bolloré collaborate on assembly, car-sharing and a new 3-seat version of the Bluecar
French firms Renault and Bolloré have agreed to join forces to promote EVs through three separate agreements: The Bolloré Group has commissioned Renault to take over assembly of the Bluecar, which was formerly built in Italy. The vehicles will be assembled at the Renault plant in Dieppe beginning in the second half of 2015. The… Read more »
