The current predominant anode material for electrical vehicle (EV) battery technology is graphite, and the large majority of this material is synthetic graphite. Most of the synthetic graphite in today’s EV batteries is made in China through a CO2 intensive industrial process that converts non-renewable petroleum derivatives into graphite. Graphite is therefore one of the largest carbon dioxide emitters in lithium-ion battery cell manufacturing. Replacing graphite with Cenate’s silicon-based materials will close to eliminate direct emissions from anode materials production.
The road transportation sector is directly responsible for around 15% of the global emissions just by fuel consumption. Substitution of fossil fuels with clean electricity, generated by renewable sources, will positively impact a key area in terms of climate change. However, the electrification of the transportation sector has challenges regarding energy storage. Current electric vehicle (EV) batteries are heavy and the driving range, or distance that an EV can go without recharging, is very limited. This range goes between approximately 300 and 650 km. Battery innovations, such as the one by Cenate, can help overcome these challenges.
Cenate’s solution will significantly increase the storage capacity of EV batteries and reducing their weight and cost by using an alternative anode material. If the solution becomes globally spread, the impacts both in direct Greenhouse Gas (GHG) avoidance and increased adoption of EVs can be substantial.
For documenting these significant avoided CO2 emissions, Cenate engaged Nysnø Climate Investments to carry out a climate footprint analysis of Cenate’s to-be industrialized silicon-based anode materials in a large-scale factory.
For every kg of Cenate’s products that are used in an EV to replace synthetic graphite, there is a direct estimated reduction in CO2 emissions of 151 kg.This represents a 93% direct CO2 avoidance by producing Cenate’s materials compared to producing synthetic graphite in China.
