Li-Ion Manufacturing: How To Optimize Raw Materials, Product Quality, And Uniformity

High Resolution, Real-Time Measurement Of Basis Weight To Assure Coating Uniformity During Lithium Battery Electrode Production Today, scientists are developing new lithium-ion battery designs for electric vehicles, energy systems and other innovative applications. The safety and efficiency of these designs rely on well-controlled manufacturing processes. Variations to the coating thickness can limit energy output or… Read more »

MIT researchers describe new electrolyte to reduce metal electrode degradation

A team of researchers led by MIT Professor Ju Li has found an electrolyte that overcomes the problems associated with metal electrodes, which could result in batteries with longer lifespans and more energy storage capacity. The research was reported in the journal Nature Energy in a paper by Li and others. The researchers say the… Read more »

MIT researchers use semisolid electrode to prevent short circuits in lithium metal batteries

Researchers may have found ways to prevent dendrite formation in solid-state batteries. Their findings are described in the journal Nature Energy, in a paper by MIT graduate student Richard Park, MIT Professor Yet-Ming Chiang and researchers at MIT and other institutions. Chiang explained, “The only way you can reach the energy densities that are interesting… Read more »

MIT study details plunge in lithium-ion battery costs

MIT researchers analyzed three decades of studies that examined the decline in lithium-ion battery prices, and found that costs have dropped by 97 percent since they were first commercially introduced in 1991. This rate of improvement is much faster than many analysts had claimed, and is comparable to that of photovoltaic panels, which some had… Read more »

Nidec to acquire Mitsubishi Heavy Industries Machine Tool to support EV drive manufacturing

Nidec, a producer of motor application products based on “everything that spins and moves,” plans to acquire Mitsubishi Heavy Industries Machine Tool. Nidec has been engaged in the manufacture of reduction gearboxes and pressing machines through its subsidiary Nidec-Shimpo. After completion of the acquisition, Mitsubishi Heavy Industries Machine Tool will become Nidec-Shimpo’s third main business…. Read more »

New emissions scandal? Tests show PHEVs emit more pollution than claimed

Sometimes it seems automakers will try any powertrain technology in order to avoid selling battery-electric vehicles. First diesels, then hydrogen, were touted as ways to reduce CO2 emissions while still maintaining the fill-er-up-with-fossil-fuel business model (and continuing to crank out the colossal SUVs that carmakers claim consumers crave). Many electric purists have long suspected that… Read more »

How to ensure EV traction motor magnets aren’t pushed beyond their operating limits

Avoiding motor demagnetization: John Wanjiku, Technical Specialist at Mentor Graphics, explains the goals of a detailed traction motor design analysis. Neodymium permanent magnets are used in EV traction motors because of their powerful magnetic fields and relatively strong resistance to demagnetization, but they tend to lose their magnetism when exposed to excessive operating temperatures, opposing… Read more »
