Japan’s New Energy and Industrial Technology Development Organization has launched the second phase of a 10-billion yen ($90 million) program to develop solid-state lithium-ion batteries for next-generation electric vehicles.

The project aims to slash the cost and charging times for solid-state systems to one-third those of current lithium-ion batteries by 2030. This would cut costs to about 10,000 yen/ kWh ($90/kWh) and charging times to 10 minutes, according to the group.
 

The initial phase, which was launched in 2013, focused on base materials. The second phase, which will run through 2022, targets solid electrolytes, electrolyte coating with active materials and the sheet formation of the electrolyte-electrode layer.

Consortium members also will develop simulation systems to predict the deterioration of solid-state lithium-ion cells and battery packs, and test evaluation methods for durability and safety.

The group includes Honda, Nissan, Toyota and 20 battery and materials companies, plus 15 universities and research organizations.
