"On Friday, the company's CEO said that it has developed a new type of synthetic graphite that could improve the lifespan and performance of electric vehicle batteries, reported. Exxon claims the new material-used in EV battery anodes-can extend a battery's lifespan by 30%. The material is being tested by multiple unnamed EV makers, according to the outlet. Graphite also has a direct impact on battery performance and efficiency, so better quality also means more range and faster charging speeds."
"ExxonMobil claims to have made a lithium-ion battery breakthrough. The company claims its synthetic graphite anode can extend an EV battery's lifespan by 30%. Synthetic graphite is an emerging alternative to natural graphite which requires extensive mining. When ExxonMobil chemist Stanley Whittingham invented the lithium-ion battery in the 1970s, few could have imagined it would one day power everything from iPhones to Teslas. But Exxon's interest in renewables waned, and other companies picked up the mantle of pushing lithium-ion technology forward."
ExxonMobil claims to have developed a new synthetic graphite for lithium-ion battery anodes that could extend electric vehicle battery lifespan by about 30%. The material is reportedly being tested by multiple unnamed EV makers and higher-quality graphite can improve performance, range, and charging speed. Exxon acquired Superior Graphite to build a synthetic graphite supply chain in the United States. Graphite functions as the anode material that stores energy, while cathodes use materials like LFP or NMC. Natural graphite mining is labor intensive and costly, and China currently controls roughly 95% of battery-grade graphite supply. Synthetic graphite offers an alternative to reduce mining dependence and support domestic EV battery production.
