Very large Li-ion battery banks were largely unknown ten years ago. Now, it is tough to keep up with the variety of uses for them. On ships, where there were no such batteries, we are starting to see 1-5MWh banks. Autonomous underwater vehicles, mining trucks and buses can sport ones of up to 350kWh but it is in stationary applications that really big facilities have arrived. Here there is a multiplier effect with Li-ion gaining market share in growth markets.
