“Solid-state batteries are much safer and have twice as much energy density as standard lithium-ion batteries.”– Karim Zaghib, General Director, Center of excellence in transportation electrification and energy storage at Hydro-Québec

Hydro-Québec (Montréal, Canada) and Dongshi Kingpower Science and Technology Ltd. (China) today announced the signing of a licensing agreement for the use of patents related to solid-state lithium batteries. This agreement will enable Kingpower to use technology developed by Hydro-Québec to manufacture batteries for the Chinese automotive market. (2018/01/22)
