A123 acquires start/stop battery technology from Leyden Energy
A123 Systems is back in the news. The battery-maker, now a wholly owned subsidiary of China’s Wanxiang Group, has acquired Leyden Energy’s intellectual property in battery materials covering lithium titanate (LTO) and non-flammable electrolyte (Li-imide) technology. As part of the deal, some of Leyden’s key technical staff will be joining A123’s R&D organization. … Read more »
Wildcat’s new copper fluoride cathode material offers 2.5x more capacity than today’s battery tech
The current generation of lithium-ion battery materials is quickly approaching its theoretical limit. In commercial layered oxide cathodes, like the popular nickel-manganese-cobalt (NMC), there is only one lithium ion for every metal. So, the most energy you could possibly store with those materials is one full lithium in and out, or about 300 mAh per… Read more »
Pomegranate-style anode could lead to next generation of batteries
The big buzz on the EV tech scene these days is about silicon anodes, which could offer ten times more storage capacity than carbon anodes. Scientists around the world are looking for ways to overcome the remaining obstacles to using silicon for a new generation of lithium-ion batteries. Researchers at Stanford University and the DOE’s… Read more »

Blue Current, a solid-state battery manufacturer, has announced technical advances, partner engagements and funding. Koch Disruptive Technologies (KDT), Piedmont Capital and Umicore invested in Blue Current in 2023. The company is using this additional funding to finish its 22,000-square-foot pilot manufacturing facility at its Hayward, California headquarters. The pilot is designed to demonstrate that the… Read more »
OCSiAl to build graphene nanotube facility in Europe
Luxembourg-based nanotechnology manufacturer OCSiAl has received a construction permit for a nanotube manufacturing plant near Belgrade, Serbia. The 120-ton-per-year nanotube synthesis factory will open in 2024 and ramp up production through 2025. The facility will synthesize nanotubes and make nanotube suspensions for lithium-ion battery makers in Europe, the US and Asia, improving the performance of… Read more »
Enevate teams with Korea’s JR to build a battery electrode manufacturing facility in the US
Korean battery firms are hooking up with US companies to get in on the stateside EV battery gold rush. The latest partnership to be announced is between US-based Enevate and South Korea’s JR Energy Solution (JR ES). JR ES boasts a unique electrode and battery cell foundry model that enables cell manufacturers to produce tailor-made… Read more »
A closer look at graphite—its forms, functions and future in EV batteries
Q&A with Graphex CEO John DeMaio Reading the EV press, you might assume that lithium, cobalt and nickel are the stars of the battery show—they get a lot of coverage, as pundits debate the relative merits of NMC and LFP cathode chemistries and agonize over looming shortages. Meanwhile, over in the anode, there’s an unsung… Read more »
