Saft joins forces with European partners to develop advanced Li-ion and solid-state tech
Battery manufacturer Saft, a subsidiary of oil giant Total, has announced that it will join forces with a handful of European partners to form a development R&D partnership focused on creating cutting-edge batteries. Saft CEO Ghislain Lescuyer recognizes that “batteries are at the heart of the current technological revolution. Their development and production play a… Read more »
Adding graphene girders to silicon electrodes could double battery life
Graphite has long been the default choice of material for anodes, but researchers dream of replacing graphite with silicon, which has ten times the gravimetric energy density. Unfortunately, silicon has several issues that limit its commercial use – it expands during lithiation, causing particles to agglomerate in ways that impede efficiency, and it is not… Read more »
Delta-Q expands family of lithium battery chargers for EVs and industrial machines
Delta-Q Technologies has introduced a new addition to its family of lithium battery chargers. The new ICL900 is a 900 W charger, designed to charge battery systems of any lithium-ion chemistry from 9 to 15 cells in series. The new charger is suitable for use on any electric machine, including scooters, floor care machines, lift… Read more »
GM and Fiat Chrysler hit with lawsuits over diesel cheating software
We may not have heard the last of the dirty diesel scandal. Two of the Big Three automakers have recently been served with lawsuits alleging behavior similar to that which may end up costing VW $20 billion. The US Justice Department has filed a civil complaint on behalf of the EPA, claiming that Fiat Chrysler… Read more »
Southwest Research Institute consortium conducts independent battery benchmarking
Comparing the spec sheets from different parts manufacturers is tricky business for engineers in any industry. However, the advanced battery market seems to be uniquely challenged in this regard. As Tesla CEO Elon Musk often points out, when it comes to batteries, the BS factor is outrageous. Even if you assume that every vendor provides… Read more »
Seaworthy EVs: Leclanché designs and manufactures Li-ion cells and systems
The advantages of electrifying transportation are far-reaching. Advanced energy storage systems are even making their way into the commercial marine industry. There are many marine applications in which adding a large Li-ion battery pack makes a lot of sense. The best-use case varies depending on the boat size and purpose. All-electric ferries, for example, are… Read more »
New supercapacitor has the potential for “astonishingly high” capacity
Supercapacitors, which can be charged rapidly and deliver intense bursts of power, are a hot topic these days. However, current supercapacitors use components made of carbon, which require high temperatures and harsh chemicals to produce. Now researchers at MIT and elsewhere have developed a supercapacitor that uses no conductive carbon, and that could potentially produce… Read more »
Powin Energy receives patent for battery pack operating system
Powin Energy, a maker of stationary storage systems, has been awarded a patent for its Battery Pack Operating System (bp-OS). The bp-OS uses an algorithm to actively and passively balance batteries down to the cell level, and also offers a picture of battery health through real-time monitoring, state-of-charge management and diagnostics. According to Powin, it… Read more »
Second life: Spiers New Technologies develops advanced battery classification techniques
Spiers New Technologies (SNT) is just over a year old, but its founder has been focused on developing the market and technology for secondary-use batteries as long as anyone in the business. Dirk Spiers is one of the more passionate figures in the EV industry. Like many entrepreneurs, he seems to have a clear view… Read more »
