3 First Cities to Get 5G; Apple May Buy Cobalt Direct from Miners; Renault’s “Smart Island”; EV Batteries May be Able to Recharge 5X FasterPosted: February 21, 2018
Even though phones don’t have it yet, the cellular providers have been busily working on building out 5G infrastructure. We have been hearing that AT&T would have some 12 markets on the super fast cellular connection that can carry vast data loads, very soon. Now, AT&T has announced that at least 3 markets will have it by the end of this year. The lucky cities are: Atlanta, Dallas, and Waco, TX. Qualcomm has announced its first 5G modem for smartphones, but it isn’t expected to actually be out and in users new phones until 2019!
With cobalt supply iffy, Apple is in talks to buy it direct from miners. According to bloomberg, the cobalt is used in iPhone and iPad batteries, as well as in EVs. Apple wants to ensure that they have enough for their products. They are apparently working on a deal to buy several thousand metric tons of cobalt per year over a 5 year period. Samsung, BMW, and VW are also working to secure long term supplies….BMW is angling for a 10 year contract. An iPhone takes 8 grams of refined cobalt…an electric car over 1,000 times more! The price of cobalt has tripled in the last 18 months…supply and demand, you know!
Renault is experimenting with an island totally free of fossil fuels. The island in Portugal, Porto Santo, will have only renewable and independent energy production and use. Solar and wind generators, the Renault Zoe and Kango utility van electric vehicles, home batteries, etch. Engadget.com reports that the more diffuse, less massive installations can be used because the island only has 5400 people plus tourists….so won’t require anything like the Tesla Powerpack mega installation in Australia.
Some researchers at University of Warwick have discovered that the lithium-ion batteries used in most electric cars can be recharged up to 5 times faster than they presently are being charged. Engadget.com says the makers have been conservative about charging, due to fear of overheating (which can cause fires and explosions.) The researchers used a fiber optic sensor protected by a chemical layer…it is inserted right into the cell, and can track the temperature precisely. In testing on over 18000 li-ion cells, they were able to quintuple charging times. The increased time does reduce battery life, but the researchers point out that if charging time could be reduced from 25 minutes to 5, it might really jump start e-car purchases.
