This is a community good discovery. A coating of goo at a university that is a government institution in CA. Who "owns" the patent? Share it for free without patent at all. Give it to China and others. There is no reason to own this by any one company.
Seems easy. Shouldn't companies be able to operate with autonomous leadership as well? Who don't need billions in payments? Getting rid of drivers on buses takes away their jobs. Autonomous trucking - no drivers, no jobs. Autonomous taxi/Uber? No payments to drivers. Why are business leaders needed at this point?
"The coated electrode holds its shape much better, making it a more reliable option," Thai said. "This research proves that a nanowire-based battery electrode can have a long lifetime and that we can make these kinds of batteries a reality."
Batteries make sense when they can be cycled 10's of thousands of times. Not 3000 to 4000 as with today's Li-Ion cells. Her finding, if mass produced at scale and low expense, marks a new age in battery tech. And I thought all these engineers working at LG Chem, Tesla, Samsung and others were working hard at battery tech challenges. Looks like a woman shows up the male scientists yet again.
University of California, Irvine researchers have invented nanowire-based battery material that can be recharged hundreds of thousands of times, moving us closer to a battery that would never require replacement. The breakthrough work could lead to commercial batteries with greatly lengthened lifespans for computers, smartphones, appliances, cars and spacecraft.
Scientists have long sought to use nanowires in batteries. Thousands of times thinner than a human hair, they're highly conductive and feature a large surface area for the storage and transfer of electrons. However, these filaments are extremely fragile and don't hold up well to repeated discharging and recharging, or cycling. In a typical lithium-ion battery, they expand and grow brittle, which leads to cracking.
UCI researchers have solved this problem by coating a gold nanowire in a manganese dioxide shell and encasing the assembly in an electrolyte made of a Plexiglas-like gel. The combination is reliable and resistant to failure.
The study leader, UCI doctoral candidate Mya Le Thai, cycled the testing electrode up to 200,000 times over three months without detecting any loss of capacity or power and without fracturing any nanowires. The findings were published today in the American Chemical Society's Energy Letters.
Hard work combined with serendipity paid off in this case, according to senior author Reginald Penner.
"Mya was playing around, and she coated this whole thing with a very thin gel layer and started to cycle it," said Penner, chair of UCI's chemistry department. "She discovered that just by using this gel, she could cycle it hundreds of thousands of times without losing any capacity."
"That was crazy," he added, "because these things typically die in dramatic fashion after 5,000 or 6,000 or 7,000 cycles at most."
The researchers think the goo plasticizes the metal oxide in the battery and gives it flexibility, preventing cracking.
You can charge LiFEPO at 5C and higher. There are some Li-Poly blends in the RC world charging at even higher 10C which is full charge in six minutes. Why is the Tesla recharge so slow at the SC?
Oh - but they are not any denser than Li-Poly blends - they need more space and are heavier per kWh than what Tesla has. I don't see Tesla using LiFEPO4 unless it is in grid storage / frequency response systems. Oh, A123 Systems was doing those as well but their cost per cell was much higher than economically sound.
You are describing exactly what a former company (now Bankrupt) A123 Systems was doing. Supplied LiFEPO4 batteries to Fisker Motors. Dan Galves loved A123 while at Deutch Bank.
Question really comes is "how do only certain analysts get invited to the call?" I think it is favorable analysts and underwriter firms only. You either are a cheerleading supporting analyst or someone at one of the banks handling their paper (loans, leases and underwriting). Let's hear from pundits and critics on these calls so that they can defend positions that are obvious.
We don't know if this is an aggregate "open accounts" total or the high-order mark of the highest series number so far. If I create a reservation, refund it, open another, refund it and open another - how many do I have?
Musk in Norway says it is 400,000. He's always wrong on guidance, though. He should give you a call.
GM beats on top and bottom lines
The auto giant topped Wall Street expectations as its net income for the first quarter of 2016 more than doubled to $2 billion. General Motor's better-than-expected earnings were driven by stronger results in North America and improved performance in Europe.
Do those oil "ministers" have math skills? It takes someone outside their region to educate them on "price will rise if you lower production"? This is a 4th grade math exercise with a bit of basic economics. However, if you want a green energy plan that itself lowers demand, you must raise prices to let those who demand that resource re-consider the amount of demand put on that resource.
