A team at Swinburne University has developed a new type of battery: a supercapacitor that charges extremely quickly.
While batteries are ubiquitous in modern society, they also have a number of disadvantages. They take a long time to charge, have a limited life, and due to their materials and construction, can be harmful for the environment if not handled properly during disposal. Additionally, some batteries can explode if they develop defects, or are improperly handled.
In contrast, supercapacitors can be charged in seconds, are reusable millions of times, and are environmentally friendly. They are also safer than ordinary batteries when mistreated, and will not explode under any circumstances.
27/January/2017 AFR article about Han Lin's Graphene supercapacitor
"Graphene comes in nano-layers or flakes of carbon molecules which can be stacked together to make a battery with vast storage, a much longer life than today's batteries and no waste disposal problems.
Cost is one obstacle. Lin and a team of researchers at Swinburne have overcome that and increased the power to weight ratio by using laser printing technology to produce graphene in an interdigital structure, which leaves ions with much less distance to travel to charge and discharge."
"Stacking layers of highly conductive graphene - they are about three-ten billionths of a metre thick - together can overcome the density problem."
