Hummers metodu ile pulcuk grafitten üretilen grafen tabakaları üzerine SnCl 2 .2H 2 O başlangıç malzemesi kullanılarak SnO 2 nanotozları büyütülmüştür. Kompozit elektrotlar taramalı elektron mikroskobu (SEM), X-ışını difraktometresi ve termal analiz teknikleri ile karakterize edilmiştir. Üretilen kompozit elektrotlar CR2016 Li-iyon düğme tipi hücreye anot olarak bağlanmış ve şarj-deşarj çevrim testleri ve çevrimli voltametre analizleri yapılmıştır. Yüksek performanslı kalay esaslı elektrot malzemesinin hacim genleşmesi problemini aşmak için malzemenin grafen tabakaları üzerine büyütülmesi ile uzun çevrim ömrü elde edilmiştir. Tek adımda üretilen SnO 2 -grafen nanokompozitinden hazırlanan elektrottan 100 çevrim sonunda 385 mAhg -1 değerinde spesifik kapasite elde edilmiştir.
