Neither Sila, nor Echion have anything to show, they call it silicon dominant anode, but it's in fact still a carbon dominant anode. Before this comes, if it ever comes, Silicon oxide >10%+ >80% graphite will play a bigger role in liion. Catl Roadmap shows no silicon anodes and as I mentioned they aren't in fact silicon anodes. With current chemistry + nitrogen+silicon dopeHuawei fits 5000mah batteries in a simple smartphone, with current chemistry and improved electrolytes Tesla can produce 16000km enduring batteries for use in Tesla taxis, current Tesla gobble up 700.000 km like its nothing. Do that with a Sila Nanotech anode on which they said it will release in 2018, then 19, now 20 for smartwatches only probably. Not ready to use in Cars they say, lol maybe in 2030. Cycling up to 500 cycles they say, nobody wants a car with 500 cycles, current NiMaCoO/graphite does over 3000-4000.Graphene coated graphite like Samsung does will be another possibility. Silicon expansion is a real hindrance and means to mitigate expansion are always at cost of other important features, there is no wonder formula, forget that
