Off-take agreement with NOVONIX advances Panasonic Energy’s commitment to carbon footprint reduction and resilient supply chain in North American— Panasonic Energy Co., Ltd., a Panasonic Group Company, today announced it has signed a binding off-take agreement with the leading battery materials and technology company for the supply of synthetic graphite, the main component of the anodes of lithium-ion batteries used in electric vehicles .
By 2031, Panasonic Energy aims to reduce the carbon footprint of the entire lithium-ion battery supply chain for EVs by 50% compared to 2022 levels. The majority of emissions arise from resource mining, raw material processing, and logistics. Therefore, in addition to reducing the carbon footprint generated during battery manufacturing through the carbon neutralization of all factories, Panasonic Energy actively addresses environmental impact reduction in the upstream supply chain.
There are two types of graphite for lithium-ion batteries: natural graphite and synthetic graphite. Synthetic graphite offers enhanced battery durability, allowing for reliable performance during repeated charging and discharging cycles. Synthetic graphite is traditionally produced by means of lengthy high-temperature treatment in an Acheson furnace, lasting 30 days per production cycle, with temperatures reaching up to 3,000℃.
NOVONIX’s proprietary graphitization furnaces are the first of its kind for large-scale production, enabling efficient mass production of synthetic graphite in just around three days per cycle. This innovation is expected to reduce the levels of CO2 emitted during the production of synthetic graphite compared to conventional Acheson furnaces.
In the North American market, encompassing the U.S. as the world’s second-largest for new car sales, Panasonic Energy aims to facilitate the widespread adoption of EVs by providing high-quality and high-capacity batteries that offer extended driving range. The company will leverage its expertise and experience to take the lead in the lithium-ion battery industry.
