Can Tanktwo redefine the battery pack with big data?

A Finnish-American start-up with ambitious goals wants to change how we think about batteries. The concept of an EV that supports the quick removal and replacement of a discharged battery pack was all the rage about 5 years ago. Since then, however, various systems have been attempted and subsequently abandoned by companies like BetterPlace, Renault,… Read more »

Formula E battery power increasing to 170 kW for season two

Williams Advanced Engineering, the supplier of the battery packs for the Formula E electric racing series, has announced that the maximum power output of the racers’ batteries will increase to 170 kW for season two of the Championship. The battery packs use cells from XALT Energy, and have maximum usable energy of 28 kWh. The… Read more »

New paper: Cost of hybrid systems will be halved by 2025

For those of us who are puzzled and discouraged by the recent decline in sales of hybrid vehicles, a new paper from the International Council on Clean Transportation (ICCT) offers plenty of hope for the future. According to “Hybrid Vehicles: Technology Development and Cost Reduction,” the costs of full-function hybrid systems are likely to drop… Read more »

Samsung says it can immediately double capacity of Li-ion batteries

Samsung Electronics has developed a silicon carbide-free graphene coating that it says could immediately double the capacity of lithium-ion batteries. That would be an impressive feat indeed, considering that capacity has increased only twofold since Li-ion batteries were first commercialized in 1991. Many researchers are investigating the potential of silicon as an anode material, but… Read more »

Researchers add compounds to electrolyte to prevent dendrite growth

Those doggone dendrites are the bane of battery boffins working on otherwise promising lithium metal anodes. Now a group of researchers from SLAC, Stanford and MIT have discovered that adding lithium polysulfide and lithium nitrate to an ether-based electrolyte can prevent dendrite growth and minimize electrolyte decomposition. Professor Yi Cui, Professor Yet-Min Chiang (a co-founder… Read more »

2015 Kia Soul EV: A strong contender in the growing EV market

Charged faithfully reports on every new plug-in vehicle that comes out, and while there are reasons to be excited about pretty much all of them, there’s always a question lingering in the background: Does this manufacturer plan to actively market its new EV, or is this just another compliance car, to be produced in limited… Read more »

This Changes Everything: Capitalism vs. the Climate (book review)

This Changes Everything: Capitalism vs. the Climate, by Naomi Klein, is a powerful, important book, meticulously researched and beautifully written. I also found it a very disturbing book, and in a way I wish I hadn’t read it. The thesis is that the kind of action required to avert climate catastrophe is incompatible with the… Read more »

VIDEO: Mister Musk goes to Detroit, presses automakers to get serious about EVs

Elon Musk spoke at the Automotive News World Congress in Detroit this week, and as usual, he had plenty to say – in an hour-long interview and a Q&A with reporters, he covered a wide range of topics. The gadfly of the automotive industry reiterated his long-standing challenge to other automakers to move faster on… Read more »

Graphene wrapper enhances performance of lithium-sulfur batteries

Lithium-sulfur batteries are of great interest, as they could offer specific energy densities far greater than those of current lithium-ion chemistries. However, current designs are plagued by low efficiency and capacity degradation. A team of researchers from the University of Cambridge and the Beijing Institute of Technology has devised a three-dimensional sandwich-type graphene sheet-sulfur/carbon composite… Read more »

Daimler invests €100 million to expand lithium-ion battery production

Daimler plans to invest around €100 million ($125 million) to expand production capacity for lithium-ion batteries at its Deutsche ACCUmotive subsidiary. A new building is under construction in Kamenz, Germany, and when it is completed in mid-2015, Deutsche ACCUmotive will have nearly 20,000 square meters of production and logistics space. “Deutsche ACCUmotive will be producing… Read more »
