Secondary battery system (Vol. 2):
Cost Estimation and Future Perspective of High-capacity Active Materials for Lithium-ion Battery
Summary
Center for Low Carbon Society Strategy （LCS） has been constructing an evaluation system for batteries, which enables to quantitatively clarify the effect of each elemental technology relating to better performance of battery and cost reduction of battery production.
In the proposal published last year, production cost of battery in present was calculated as 17.6 JPY/ WhST, based on detailed process analysis. Moreover, battery cost was preliminary estimated, considering future technology development, scaleup effect and the use of high energy density materials. In the follow-up proposal, a novel battery using innovative cathode and anode activity materials was determined based on product shape and evaluated by the process design approach. The results reveals that production cost of battery is likely to be reduced from 17.6 JPY/ WhST to 5.1 JPY/ WhST in year 2030. Furthermore, research and development subjects were discussed based on the evaluation results.
