This questions boils down to the following important questions:
- Do we physically have enough materials in the earth's crust to make enough lithium ion batteries to support global storage demand?
- Can we produce lithium ion batteries at a cost/kWh to make it economically feasible? Many speak of the supposed $100/kWh barrier, but at what cost per kWh do we need to compete with existing non-renewable energy sources?
Lithium ion batteries have been the most talked about means of storage for renewables, but can they solve the world's energy storage problem to support a transition to renewable energy?
