Stanford Ovshinsky, Hybrid Car Battery Inventor, Has Died

another random user writes "Stanford Ovshinsky, a self-taught American physicist who designed the battery now used in hybrid cars, has died aged 89 from prostate cancer . The electronics field of ovonics was named after Mr Ovshinsky, who owned over 200 patents and has been described as a '[Thomas] Edison of our age.' He introduced the idea of 'glass transistors' in 1968, which paved the way for modern flat-screen monitors."

    ...my dad was a physicist at ECD (when Ovshinsky owned it) in Troy, MI back in ca. '70 and I was about 8 years old at the time. We used to go to his house for dinner and BBQs a lot and he would stock my favorite pop (strawberry Faygo) for me at his house. He was a very nice guy.

Mr. Ovshinsky is a prominent figure in the program, showing off his solar cells, hydrogen storage media, and other inventions. The guy was truly remarkable and seemingly always thinking. We need more like him, people who are thinking of ways to improve the world (not just make money).

      They're not even used in most hybrids now, because the world has moved on to Lithium. They were used in the original Honda Insight, but the technology was sold to Chevron who placed it under onerous licensing terms. Even R/C cars and rechargeable flashlights have moved on from NiMH to LiPo or LiFePo.

      No he didn't. His company holds a number of patents regarding the use of NIMH batteries, particularly in automobiles, but he cannot be regarded as the sole inventor of the NIMH chemistry used in related batteries. R&D into this domain started in the 1960s. In the mid 1980s working but expensive NIMH batteries existed for specialized applications like powering satellites. However he contributed to find a way to replace expensive rare earth materials by something cheaper, paving the way to mass market availability of the technology. However most NIMH batteries bought at some store today are not necessarily based on his design.

      Modern science very rarely involves a single scientist inventing something amazing by themselves.

      Most hybrid cars still use NiMh. Look at Toyota, the most popular maker of hybrids. All of the 2012-2013 Prius models use NiMh except for the plug-in Prius. The big problem with any rechargeable has been battery life. NiMh cells last pretty much forever as long as you run only part of their capacity. The first two Prius generations (1997-2000, 2001-2003) used only 40% of the battery capacity. From 2004 on, they boosted this to 60%.

      The full electric cars have largely jumped to Lithium for energy density. But Lithium charging is more complex than NiMh -- cells can't deliver or take as much instantaneous power. So they make much more sense in large packs, but not as much for smaller pack, yet. Much of the work on new Lithium formulations (including the work the now-defunct A123 was doing) is improving the anode and cathode materials, which will increase their peak power/charging capacity, and increase the useful life.

      For R/C cars, yeah, Lithium cells exist, but the majority are still using NiMh. It's much the same issue -- serious racers need peak power output, which is fairly small from Lithium cells vs. NiMh (in fact, some even prefer NiCAD, despite the evil memory effects, as they can deliver a higher current peak than a similar NiMh cell). Some of this is addressed in the LiFePO4 cells, which are starting to gain traction.

      Another issue with Lithium cells is that it's critical to monitor power levels. Over-discharging can cause a parasitic reaction in the negative terminal, production of LiO in an irreversible reaction. Even without that, there are a number of parasitic effects in most classic Li-ion cells that limit their lifetime, often to about 3 years or less, independent of the battery cycling. That's been a biggie for use in hybrids, and one reason NiMh still dominates -- all of the hybrid or BEV cars out commercially now, with Lithium based cells, are using very new battery designs.

    I worked for ECD for 3 years just before and just after Stan "left" (corporate code for "was forced out"). It was one incredible place and he was a pretty incredible guy. So many interesting inventions that unfortunately never really got off the ground. That was partly because Stan tried to treat each of his inventions as a thing to be nurtured, even when it was clear that they were either un-economical or ahead of their time and partly because he partnered with a lot of big companies that stole the stuff they wanted and buried the stuff they wanted buried. (Who Killed the Electric Car? (2006) www.imdb.com/title/tt0489037/synopsis) Stan also had a knack for trusting that his employees had his back when they didn't and often went off on their own tangents. And the business was never what it was about for Stan. The money was just a way to keep inventing. Still, Amorphous Silicon for both sunlight to electricity AND electricity to light, dozens of CD/DVD patents (that Sony tied up so tight they could never be monetized), Nickle Metal Hydride batteries (that Chevron locked up), Phase Change Memory that nobody seemed to be able to make money at. Multi-State Phase Change Logic which was late in his career and maybe never got the attention it should have, a way to make buckets of hydrogen from almost anything organic and a way to safely store it in an auto fuel tank as a hydride. (ECD had company cars that were retrofitted Priuses running on pure hydrogen stored a s hydride). Stan was convinced that the Hydrogen economy was just around the corner. That is just scratching the surface. Brilliant, irascible, fun loving, generous, bull headed, curious, a know it all, in short a real human being. RIP Stan.

    And all the professional physicists and engineers denied that amorphous semiconductors were possible for many years, even when confronted with evidence... See for example:
    http://www.telegraph.co.uk/news/obituaries/9621164/Stanford-Ovshinsky.html
    "In 1960, with his second wife Iris, a biochemist, he founded Energy Conversion Laboratories (later renamed Energy Conversion Devices, or ECD) at Rochester Hills, Michigan, to develop his ideas, and in 1968 held a press conference at which he announced that he had succeeded in making a "glass transistor" that relied on a principle which (with understandable immodesty) he called Ovonics. This breakthrough, he predicted, would eventually lead to desktop computers and television sets "hanging like portraits on the wall". The announcement made the front pages and ECDâ(TM)s stock (the company went public in 1967) soared. Within days, however, semiconductor engineers dismissed the idea and ECDâ(TM)s stock price collapsed. Most scientists had never heard of amorphous materials, and some rubbished Ovshinsky as a high school dropout and former machinist with no university qualifications. He was branded a crank. Eventually, though, Ovshinskyâ(TM)s theories proved correct, ushering in a whole new field of solid-state physics."

    I can wonder if we'll see the same with so-called "cold fusion" (LENR)? Example:
