The huge volume expansion in Sn-based alloy anode materials (up to 360%) leads to a dramatic mechanical stress and breaking of particles. resulting in the loss of conductivity and thereby capacity fading. To overcome this issue. SnO2@C nano-rattle composites based on 2 nanoparticles in and on porous amorphous carbon spheres were synthesized using a silica template and tin melting diff... https://fitnessgravesyardes.shop/product-category/left-post-cover/
