24M emerges from stealth mode with new semi-solid Li-ion cell; <$100/kWh by 2020

Green Car Congress

Stealth-mode battery start-up 24M has introduced its new semi-solid lithium-ion cell. Together, our inventions achieve what lithium-ion has yet to do—meet the ultra-low cost targets of the grid and transportation industries. By 2020 our battery costs will be less than $100 a kilowatt-hour (kWh).

Anderman report sees strongest growth for full-hybrid systems; Li-ion batteries for hybrids may be in short supply

Green Car Congress

Low-cost 14V micro hybrid systems and full (strong) hybrid (i.e., Although NiMH is still the dominant battery in the high-voltage hybrid market, Li-ion technology started to take market share around 2009 and is expected to continually increase its share with time. Li-Ion batteries for strong hybrids are in short supply.
