Ge nanocoatings as anode for three dimensional Si based Li ion microbatteries

Ge nanocoatings as anode for three dimensional Si based Li ion microbatteries

Three dimensional (3D) hedgehog-like Ge nanoelectrodes coated on patterned Si substrate are successfully fabricated through the facile chemical vapor deposition (CVD) process. The 3D Si substrate with enlarged surface area and the abundant Ge shell electrode configuration are together favorable to e...
