Technical Description In the prior art of high-efficiency anode materials for lithium-ion batteries, we designed a high-entropy compositionmanufactured it through a simplemass production method. This technology inherits the cocktail effect of high-entropy alloys by combining highly active elementsmetal elements. This material can be manufactured by a simple mass production method. It shows high energy density, high Coulomb efficiencyhigh cycle stability,becomes a promising anode material for lithium-ion batteries.
Scientific Breakthrough Compared with graphite with a theoretical capacity of 372 mA hg-1, siliconother alloys have a higher theoretical capacity ( 900 mA hg-1), but have lower cycle stability. This technology is different from other alloy-type lithium-ion battery anode materials. Based on formula design, we use a simple mechanical alloy method to synthesize high-entropy anode materials. These anode materials exhibit excellent electrochemical performance: the capacity is 3 times higher than that of graphite,the cycle stability is 3 times higher than that of pure silicon.
Industrial Applicability Lithium-ion batteries are widely used in our daily life, including notebooks, mobile phones,electric vehicles. This technology introduces the alloy-type anode material of lithium-ion battery in a simplemass-manufactured method. These anode materials exhibit excellent electrochemical properties: the capacity is 3 times higher than that of graphite,its cycle stability is 3 times higher than that of pure silicon.
