Most applications for batteries care about their size and weight
Actually, one of main applications for batteries in the near-to-medium future is gonna be grid storage to supplement the explosive growth of renewables, and home backups to make the grid more distributed and replace diesel/gas generators during blackouts. For those purposes you don’t really care about the size, really don’t care about the weight, and a cheaper, more stable, less fire-prone chemistry suddenly becomes very appealing.
I agree with you that lithium is not going anywhere for a while, it’s the best fit for many applications like EVs, drones, etc. But I wouldn’t be surprised if its share in the battery market drops significantly over the next 10-15 years.
