Lithium-ion batteries: Further GS Yuasa troubles

Toyo-keizai Online, Yomiuri-online and Livedoor Online News in Japan have recently reported in Japanese on further problems with the large lithium-ion batteries produced by GS Yuasa, the Japanese company involved in the grounding of the Boeing Dreamliner worldwide due to fires in its lithium-ion batteries but also supplying lithium-ion batteries to the International Space Station.

GM to produce next-generation electric car in South Korea

General Motors will produce its next-generation electric cars in South Korea.

Boeing Dreamliner: Implications for electric vehicles

IDTechEx analysts have ten years of experience of the lithium-ion traction battery business and in this article they comment on the implications for electric vehicles land, water and air of these Dreamliner batteries that are not for traction, apparently misbehaving.

Will iron batteries return?

Electric vehicles whether hybrid or pure electric or for land, water or air, employ batteries on board, where supercapacitors have not replaced them.

A123 Systems agrees to sell automotive business to Johnson Controls

A123 Systems has entered into an asset purchase agreement with Johnson Controls valued at $125 million.

Next generation EV batteries to be produced in France

The results achieved by the R&D Laboratory of Renault and the CEA in new-generation batteries for electric vehicles have made it possible to enter the preparation phase for industrial production, to begin in 2017 in France, with the contribution of the South Korean battery manufacturer, LG Chem, a world leader in the sector.

SK Innovation wins patent lawsuit against LG Chem

SK Innovation has won a patent suit against LG Chem over separators for Li-ion batteries.

Big disagreement on where lithium-ion batteries are headed

Lithium-ion is the winning type of rechargeable battery for the decade - there is almost a consensus. You can count about 150 manufacturers of these and IDTechEx has profiled nearly all of them.

A123 goes niche too late?

Following a redundancy, rehiring and large quality recall, struggling lithium-ion traction battery maker A123 Systems is trying some niche marketing now that most of the orders for the world's hybrid and pure electric car batteries over the next three years have been cornered by the big four - LGChem, Panasonic inc Sanyo, AESC and SBLimotive as analysed in detail by the Institute of Information Technology of Japan.

Blunt motor and battery talk at EV Japan

The conference speakers were surprisingly blunt in their appraisal of batteries and motors for electric vehicles at last week's EV Japan conference. Batteries control the cost of pure electric vehicles by a big margin and they are the largest part of the cost of hybrids, though a lesser percentage.

Distinguishing good from bad Li-ion battery suppliers

It is now urgent for the good manufacturers of lithium-ion traction batteries and their systems in electric vehicles to be distinguished from those encountering problems.

Penetrating the fog surrounding lithium-ion traction batteries

To penetrate the fog surrounding lithium-ion traction batteries we should use the term generically for all rechargeable batteries involving lithium ions. For example, it is false to talk of lithium polymer as an alternative to lithium-ion because the term lithium polymer simply refers to a form of electrolyte involving solid polymer electrolyte usually with gel.

Can Sony Li-ion batteries recover market share?

Sony was once the leader in the lithium-ion "Li-ion" battery market. In 1991, it was the first in the world to commercialize them. It has focused mainly on compact batteries for PCs and mobile phones. The lithium-ion battery market continues to expand, driven by strong demand for mobile phones, PCs and now electric vehicles. For example, such batteries are seen in an increasing minority of pure electric forklift trucks and boats, in most off-road electric vehicles and in virtually all Autonomous Underwater Vehicles AUVs, electric aircraft and electric airships, not just in on-road electric vehicles from buses to trucks, cars and some e-bikes. Sony is noticeably absent from all this vehicle activity, despite Sony CEO Howard Stringer announced plans, in 2009, to enter the automotive battery business.

Best for batteries: Not too hot, not too cold

With average U.S. gasoline prices approaching $4 a gallon, drivers and automakers are thinking electric. Previously steered in this direction by concerns about pollution and dependence on foreign oil, consumer interest in electric-drive cars continues to surge. But before Americans are able to flip the switch from gasoline to electricity, automakers need batteries for the next generation of electric vehicles that can deliver the range, performance, reliability and safety drivers expect.
