Oldie, in one of my previous incarnations I was doing electrical engineering so I do keep an eye on matters electrical. I also, like most of us, keep an eye on matters environmental. The lithium battery is a limited and ultimately dead end technology. Capacitor batteries perhaps used in tandem with lithium would provide improvements to energy loss from depletion due to high discharges to my overcome inertia etc.......or capacitor batteries themselves may be developed to outperform lithium especially with charge times, and lifetime recycles. However, at he moment hydrogen just looks to be better at many levels. For environmental concerns, carbon footprint and other pollution the reality is it’s far better to just keep an existing car on the road, regardless of fuel type. Looking to the future and dare I say TUNGSTEN; lots of applications for it particularly good in newly developed solar panels and other applications, particularly where gold has previously been seen as the go to metal for its electrical properties. The other big thing with metal moving forward has to be the rare earth metals used to create alloys with high magnetic or others that have very high magnetic energy density. They are needed for the electrical motors ( you can’t use great big ferro based metal because of the size and weight for the same energy). So why everyone is looking at lithium for batteries it’s a red ‘herring’, for me its the hydrogen cell and possibly carbon nano tube capicitors, and the rare earth metals for magnetics. That’s if we get there before the world is toast. Incidentally this extinction rebellion mob, if they really care about the environment should ;protest against those buying lithium battery cars ( huge footprint and pollution) and get people to carry on with their existing cars, then go to China and protest against the all the coal fired power stations and fluorocarbons they release, then go to India and do similar, then go to Russia and then Brazil over deforestation, then go to the UN and do something about the massive ships using waste oil as fuel without filtration once they are outside maritime waters. That way I wont be held up and they can do some good in the world. In the meantime someone needs to get nuclear power plants up and running, nuclear waste can be dealt with more easily than giga tons of carbon. With regard to safety on nuclear power stations the Rolls Royce plants that they proposed had been used in submarines ( proven 50 year safety record). They could be strategically placed, so although smaller outputs than the mega sized plants they compensate for by far less transmission losses. These projects would, of course, require alloys with tungsten and also to some extent molybdenum- which was also discovered by Mr Scheele.
