FDK and Fujitsu develop novel cathode material for solid-state batteries

FDK and Fujitsu Laboratories have jointly developed lithium cobalt pyrophosphate (Li2CoP2O7) as a cathode material for solid-state lithium-ion batteries. The new material can operate at charge/discharge voltages of more than 5 V, which is beyond the limits of current lithium batteries. The energy of a battery is a function of its voltage and capacity, so an… 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 »

Former Tesla execs launch plan for European Gigafactory

A couple of Tesla alumni, with backing from Swedish investors, have announced a plan to build a massive Li-ion battery factory, perhaps in Sweden or Finland. Their ambitious goal is to bring the cost of batteries down to $100/kWh. Tesla’s former Vice President of Supply Chain Management, Peter Carlsson, and another former Tesla supply chain… Read more »

AKASOL says its battery modules ace long-term endurance tests

German battery builder AKASOL subjected the latest generation of its battery modules, AKAMODULE 46Ah and 53Ah, to an eight-month endurance test featuring a range of brutally extreme conditions. The test showed service life to even longer than expected. At 50 to 55 degrees, the battery components worked for 1.5 years in full cycles at a… Read more »

A123 Systems to supply Li-ion batteries for 48 V systems to GM’s Chinese JV

Automotive News China reports that battery maker A123 Systems won a contract worth approximately $1 billion to supply 2.6 million Li-ion batteries for 48 V systems to the SAIC-GM joint venture in China. A123 initially entered into a partnership with SAIC Motor in 2009 with the formation of a battery pack joint venture called Advanced… Read more »

Battery management system maker Dukosi lands £2 million in funding

Scottish battery management systems innovator Dukosi has secured £2 million in new investment funding, led by IP Group. Dukosi has developed a battery management system (BMS) that collects, processes and stores data directly at the cell. Using wireless technology, the system transmits real-time information on cell performance to support master-level control of the battery pack…. Read more »

New protocol reduces Li-ion battery formation time by a factor of six

A new process developed by the Oak Ridge National Laboratory could alleviate a bottleneck in battery manufacturing and deliver higher capacity batteries. It also conserves lithium, which improves battery capacity. In “Fast formation cycling for lithium ion batteries,” published in the Journal of Power Sources, Seong Jin An and colleagues explain that the formation process,… Read more »

Chinese battery-maker and Finnish manufacturer partner to supply battery packs to Europe

Chinese battery builder Contemporary Amperex Technology Limited (CATL) and Finnish contract manufacturer Valmet Automotive have formed a strategic partnership to develop electric automotive solutions. As part of the deal, CATL has taken a 22% ownership position in Valmet. CATL currently offers NCM and LFP Li-ion chemistries in cells, modules and packs. The companies’ strategy is… Read more »
