摘要
Abstract
Traditional hot-air drying is energy-intensive and time-consuming,whereas infrared drying has the potential for energy efficiency and high speed.However,issues such as uneven light field distribution and low energy utilization efficiency remain to be addressed.The design of an infrared light homogenization drying system is proposed,which optimizes the spatial distribution of infrared lamps to improve irradiance uniformity and energy utilization efficiency,thereby enhancing electrode performance.The system achieves an irradiation uniformity of 95.42％and an energy utilization efficiency of 38.98％,representing 109.97％and 313.60％,respectively,of those obtained without the homogenization system.The drying time is shortened from 350 s using hot-air convection to 21 s.Furthermore,the dried electrodes exhibit excellent mechanical properties and electrochemical performane,with an adhesion strength of 17.19 N/m,which is higher than that of electrodes dried by hot-air or non-homogenized infrared,the rate capability of half-battery is similar to that of hot-air.The infrared homogenization drying system reduces the cost of the current battery production,while enhancing production efficiency and process quality.关键词
