AI Technical Summary
Existing silicon-based negative electrode active materials for secondary batteries face challenges in achieving high initial coulombic efficiency and cycle capacity retention, which are crucial for improving the performance of secondary batteries in various applications.
A silicon-based negative electrode active material containing a combination of K and Mn elements, forming a silicate structure with oxygen-containing silicon moieties, enhances lithium ion desorption ability and electron conduction, thereby improving initial coulombic efficiency and cycle capacity retention.
The combination of K and Mn elements in the silicon-based negative electrode active material significantly improves the initial coulombic efficiency and cycle capacity retention, enabling secondary batteries to achieve high cycle performance and energy density.
