Thank you for this excellent review. - I have some questions: 1. What is the reason to focus on polycristalline cathode materials rather than monocristalline? 2. What do you think about alternative manufacturing methods, like 3D printing? Could it be interesting with regard to increase the volume of cathode (and anode)?

For the first point, I think it might be due to the fact that grain boundaries can serve as diffusion paths for Li ions, improving the power density.

Also, monocrystalline may not be all it’s cracked up to be

No, although vw supposedly said testing is going well I think they are far behind in certain areas that will limit their commercial application

Hey guys I'm from Ethiopia. I'm working my PhD thesis on Ni-rich cathode materials; what could you help me please?

The fact is lot of batteries are carelessly discarded and humans should not be contaminating waterways and soils with items like this. The inevitable toxicity of batteries in the environment is something that could be improved by manufacturing industry or international agreement. If bottles and cans are important enough to have this kind of system then surely it it is disgraceful that we only worry about improving the value to the users who don’t really care about the quality of the item or what’s inside it or whether it’s supposed to be ingested or burnt or whatever! IMHO a scheme where anyone can get an actual cash reward for returning batteries to an approved recycling or safe disposal location. Perhaps making an individual unique code on each and every battery is a good idea? The expected safe useable lifespan could be publicly available on an agreed website which should be accessible by anyone to see - less fires in unexpected places in the years to come? Regardless of cost the morally correct thing to do is take responsibility for it right from the start or maybe we could start now… One day future generations might be able to use the rare earth metals we put into a big hole in the ground somewhere. Actually we could do that with radioactive waste - ignoring it won’t make it better. Anyway I know who has the best shirt 2:00:36 BTW I want my naming rights and a share of the royalties for my hoverboard encrusted with diamonds that I shall expect to be delivered via courier in a day that ends in w.
