AI Technical Summary
Technical Problem
Existing methods for lithium replenishment in lithium batteries result in high lithium consumption and low efficiency, leading to resource waste and inadequate cyclic performance.
Method used
A negative electrode plate design with staggered and spaced lithium bands on the substrate surfaces, optimized by specific geometric relationships and manufacturing processes, enhances lithium diffusion and utilization.
Benefits of technology
The design improves lithium battery cyclic performance by reducing lithium consumption and increasing diffusion rates, resulting in enhanced long-term capacity retention.
