Research and Development Targets
1. Storage batteries
A. R&D of high-performance storage batteries and materials.
- By 2030, develop technologies for storage batteries and materials with the aim of realizing storage batteries with volume energy density of at least 700-800 Wh/L (e.g. solid-state batteries) or storage batteries with output density of at least 2,000-2,500 W/kg and volume energy density of at least 200-300 Wh/L, assuming a package equipped with performance, size, etc. needed for automotive purposes.
- Develop materials technology for reducing usage of specific high-dependency materials such as cobalt and graphite; production technology for reducing GHG emissions during manufacture of materials and components; and production technology for enabling highly efficient production.
B. Development of technology for storage battery recycling.
- Develop technologies to recover at least 70% of lithium, 95% of nickel, and 95% of cobalt (single metal equivalent) at costs no higher than market prices (either compound or single metal prices) with a level of quality that enables their reuse in storage batteries.
2. Motor field
A. Development of high-efficiency and high-power-density technologies for mobility-related motor systems.
- Aim to realize motor system average efficiency of 85% and motor unit output density of 8.0 kW/kg and motor system output density of 3.0 kW/kg.
Assumptions regarding estimates of CO2 reduction effect
- As a result of the commercialization of the storage batteries and motors being developed under this project, the dissemination of EVs and PHEVs is assumed to accelerate and reach the levels envisaged in the IEA’s Beyond 2℃ Scenario (B2DS). (In 2040: 411 million EVs and 184 million PHEVs; In 2050: 911 million EVs and 342 million PHEVs)
- The percentage of EVs and PHEVs using technologies realized under this project is assumed to total 30% by 2040 and 50% by 2050. Reductions in CO₂ emissions have been estimated under a scenario where EVs and PHEVs have entirely replaced conventional internal combustion engines vehicles.
Assumptions regarding estimates of economic effect
- Using the dissemination number of EVs and PHEVs envisaged in the IEA’s B2DS, the sales number of EVs and PHEVs using technologies realized under this project in 2040 and 2050 has been calculated by taking into account the rates of dissemination noted above.
- Estimates calculated under assumption that average sales price for EVs and PHEVs in 2040 and 2050 will be 2 million yen.
