DOE researchers identify cause of cathode degradation in nickel-rich materials

A team of scientists that includes researchers at the DOE’s Brookhaven National Lab and SLAC National Accelerator Lab has identified the causes of degradation in nickel-rich materials for lithium-ion battery cathodes, as well as possible remedies. Researchers at Brookhaven are part of a DOE-sponsored consortium called Battery500, a group that is working to triple the… Read more »

Williams Advanced Engineering creates cheaper carbon composites

Williams Advanced Engineering (WAE), a UK-based tech and engineering firm, says it is working on new carbon composites that offer comparable performance to existing options, but at a cost that brings them within reach of mainstream applications. WAE says carbon fiber reinforced polymer’s (CFRP) high strength-to-weight ratio, stiffness, and resistance to fatigue and its environment… Read more »

Five NATO countries field-test Epsilor 6T Li-ion battery as lead-acid replacement in military vehicles

Epsilor, a developer and manufacturer of mobile energy products for defense and aerospace, showcased the latest version of its 6T NATO-standard Li-ion battery at the recent International Armoured Vehicles show in London.

Rice University adds red phosphorus to separators to foil dendrites

Rice University scientists have found that adding a layer of red phosphorus to separators in lithium metal batteries can signal when damaging dendrites threaten to create a short circuit. Rice University chemist James Tour made lithium metal test cells with a coat of red phosphorus on the separator, which keeps the anode and cathode electrodes… Read more »

Nidec announces in-wheel motor prototype

Motor manufacturer Nidec has announced a prototype for an in-wheel EV traction motor. The company aims to begin mass production of the motor around 2023. The prototype motor fits within the wheel hubs of an EV, a design which Nidec claims allows for higher efficiency and lighter, more compact designs than motors occupying the engine… Read more »

ALD’s six-channel printed circuit board automatically balances any size supercapacitor

Advanced Linear Devices (ALD), a California manufacturer of analog technology, has created a six-channel supercapacitor automatic balancing (SAB) printed circuit board (PCB). ALD says the board, known as SABMB6, can balance any size supercapacitor with zero added power dissipation. Each PCB can balance up to six supercapacitors stacked in a series, ranging from six to… Read more »

Researchers add MXene to silicon anodes, improving charge life

Researchers at Drexel University and Trinity College have found that using silicon fortified with a special type of materials called MXene in Li-ion anodes could improve charge-to-charge life of batteries. The group reports in Nature Communications that the latest Li-ion batteries on the market are likely to extend the charge-to-charge life of phones and EVs… Read more »

Battery metals see bigger gains in 2018 than EVs thanks to increasing battery capacity

In 2018, global deployment of nickel, graphite, copper, LCE, aluminum and cobalt by cell suppliers for passenger vehicles increased by 75% to 99% over the previous year, according to data from Adamas Intelligence’s EV Battery Capacity and Battery Metals Tracker. These growth rates are particularly remarkable considering that global EV registrations increased by just 67% over the… Read more »
