Thus far continual incremental improvements and mass-production have been more effective in driving lithium-ion battery performance up and prices down rather than dramatic breakthroughs:
- Electric car battery costs already cheaper than 2020 predictions: Study – VentureBea/Stephen Edelstein/Green Car Reports
- Electric vehicle batteries ‘already cheaper than 2020 projections’ – Carbon Brief
This process may plateau, of course, and then leaps in technology like solid state batteries will be needed to make further progress towards lowering battery costs.
