LG Chem secures international patents for its safety-reinforced battery separator

LG Chem, the world’s largest lithium-ion battery maker, has obtained a patent for its safety-reinforced separator (SRS) in Europe and Japan. The company already has patents for the technology in South Korea, the US and China. The separator is an important component of lithium-ion polymer batteries, separating the negative and positive poles to prevent internal… Read more »

DOE offers $10 million in research funding for batteries, motors and power electronics

If you’ve got an idea for cheaper, lighter, safer or more durable batteries or electric powertrain components, you may be eligible for a piece of a new $10 million pot of research funding. The DOE’s Vehicle Technologies Office (VTO) has issued an Incubator Funding Opportunity Announcement (FOA) for projects that address any of several “areas… Read more »

NC State University to lead new institute for next-generation power electronics

President Obama has announced the selection of a consortium of businesses and universities to lead a manufacturing innovation institute for next-generation power electronics. Last May, the President committed $200 million in federal funding to three new regional hubs, designed to bridge the gap between applied research and product development, and launched a competition to select… Read more »

South Korean team develops coated LMO cathode that lasts longer at high temperatures

The quest for the better battery involves ongoing research on improving and optimizing materials used for lithium-ion cells. One such material is LiMn2O4 (LMO), which offers high power and low cost, but cell life at high temperatures can be problematic. In a paper in Nano Letters, a team from the Ulsan National Institute of Science… Read more »

PowerGenix and Amperex partner to manufacture high-volume nickel-zinc batteries

PowerGenix, a developer of rechargeable nickel-zinc (NiZn) batteries, has signed a Memorandum of Understanding with Asian battery manufacturer Amperex Technology (ATL). ATL will become PowerGenix’s partner for the high-volume manufacturing of NiZn batteries. According to PowerGenix, nickel-zinc is the ideal chemistry for Stop-Start (or is it Start-Stop?) systems. Whatever you call it, the technology, which… Read more »

New anode extends the life of lithium-sulfur batteries

Many researchers are interested in lithium-sulfur batteries, because they can offer up to four times the energy density of lithium-ion chemistries. However, current lithium-sulfur batteries have a much shorter lifespan. In a paper published this week in Nature Communications, a team from the Department of Energy’s Pacific Northwest National Laboratory (PNNL) described a “hybrid” anode… Read more »

Gigavac’s new sealed high-power contactor is rated for 1,000 amps continuous duty

Gigavac has announced an addition to its line of Advanced Switching Solutions. The new GX110 contactor is rated for continuous duty up to 1,000 amps, and is capable of switching high current loads at voltages up to 800 DC.  A contactor is an electromechanical device that switches high voltage and current by means of a… Read more »

Porous Power’s ceramic battery separator aims to enhance performance of Li-ion batteries

Porous Power Technologies has announced the launch of Symmetrix NC2020, a ceramic battery separator designed to improve thermal stability and safety of large-format lithium-ion batteries. “Symmetrix NC2020 is non-flammable and more resistant to shrinkage than conventional separators,” according to the company. “This makes cells more stable when damaged or abused and can prevent or delay… Read more »

Silicon nanowire batterymaker Amprius raises $30 million in Series C funding

Amprius, a developer of lithium-ion batteries using silicon anodes, has raised $30 million in a Series C funding round, which it will use to commercialize its batteries and further develop the next generation. The company introduced its first generation of batteries in May 2013, and is supplying smartphone and tablet OEMs with its first two… Read more »
