Mazda Motor Corporation, ELIIY Power Co., Ltd. and Ube Industries, Ltd. have agreed to jointly develop lithium-ion batteries for use in automobiles. The three companies will work together to develop durable, heat- and impact-resistant 12-Volt lithium-ion batteries as a viable replacement for lead-acid starter batteries in motor vehicles by 2021.

Lithium-ion batteries offer a promising alternative to conventional lead-acid car batteries, as environmental regulations in some regions restrict the use of lead and engineers aim to reduce vehicle weight for improved fuel economy. But their application in motor vehicles so far has been limited due to the need for car batteries to withstand the high temperatures of the engine room and the potential impact forces of a collision. With this new project, Mazda, ELIIY Power and Ube Industries will combine their technical strengths to overcome such issues.

Making use of the industry-leading computer-aided model-based development techniques it honed while developing SKYACTIV Technology, Mazda will conduct model-based research of the chemical reactions that occur inside batteries, develop technologies to manage high-performance batteries from a vehicle-total perspective and develop a general purpose model for their use.
