article_snippet: And although the higher temperatures used to create other sheets create a more layered arrangement of carbon atoms to maximise  performance, Drs Pol's less-ordered materials are said to have a 15 per cent higher electrical storage capacity.
article_snippet: By comparison, the 'disordered crystal structure' of Purdue University's sheets (shown) lets them store more lithium ions than the theoretical limit - making them more powerful .
article_snippet: [The batteries] have disordered, porous structures,' said Dr Etacheri.
article_snippet: the 'disordered crystal structure' of Purdue University's sheets (shown) lets the 'disordered crystal structure' of Purdue University's sheets (shown) store more lithium ions than the theoretical limit, and the 'disordered crystal structure' of Purdue University's sheets (shown) porous microstructure lets the lithium ions quickly diffuse into the microsheets and creates more surface area for electrochemical interactions.'
