POWER THAT BENDS 75highly conductive copper and nickel metal particles onto the polymer. The resulting metallic fabric is more conductive than metal foils and has a larger surface area for storing charge, resulting in excellent electrical performance. Despite a thickness of less than 0.5mm, a textilebased lithium-ion battery can store more than twice the amount of electricity as a bendable lithium battery of the same volume %u2013 a battery the size of a name card can store 200mAh of energy. This high conductivity also enables faster charging. After 500 charge-and-discharge cycles, the battery still retains 80% of its original energy capacity and can last for up to 1,000 cycles.Ideal professional sports apparel should be able to tolerate the physical demands of various sports and resist normal wear and tear. The textile-based lithium-ion battery offers an extra competitive edge in this regard as it can withstand harsh mechanical impacts without breaking down or posing any safety hazards. In tests, the battery functioned normally after being repeatedly folded in half, twisted at different angles, and crumpled over 1,000 times. It was then
