Long-lasting lithium battery with breakthrough tech to boost EV range

Scientists have developed a breakthrough method to create safer, longer-lasting lithium-ion batteries (LIBs) by enabling unlimited customization of full concentration gradient (FCG) cathodes, particularly in high-nickel materials used for electric vehicles (EVs). Traditional cathode synthesis methods limit the ability to independently control composition gradients, as adjusting one parameter affects others. The new approach employs a mathematical x-framework combined with an automated reactor system, allowing precise, independent tuning of multiple parameters such as average composition, slope, and curvature in the cathode material. This innovation overcomes previous constraints by expressing the flow rate of metal precursor solutions as a time-dependent function, enabling a virtually unlimited range of concentration gradients from just two precursor tanks. High-nickel cathodes are favored for their high energy density and cost efficiency but suffer from stability and safety issues due to intensified side reactions. The new method addresses these challenges by producing finely tuned FCG Ni0.8Co0.1Mn0.1(OH)2
