NOVELTY - Absorbing terahertz wave as battery complementary electric quantity comprises combining the high-purity hexagonal boron nitride/graphene composite material combined on the cathode side of the main battery or the high-purity hexagonal boron nitride/graphene composite material is made into the cathode of the main battery, where the high-purity hexagonal boron nitride/graphene composite material absorbs the terahertz wave in the environment to generate electronic directional movement and the small battery connected in series with the main battery supplies a electric quantity to the main battery and prolongs the endurance time of the main battery. USE - The method is useful for absorbing terahertz wave as battery complementary electric quantity. ADVANTAGE - The method uses high-purity hexagonal boron nitride/graphene composite material, which is very light, does not take up space and does not increase the battery volume, can effectively increase the battery energy density, is durable and suitable for high-capacity energy storage lithium batteries and shortens the battery charging time. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for battery using terahertz magnetic wave to supplement electric quantity. The main battery is a lithium ion battery. The main battery is LFP battery.
