“We had to repeat the experiments several times to verify that it was not an error”: Karolina Matuszek, from Monash University (Melbourne, Australia), and her colleagues were very surprised by the capacity to store the heat of a mixture of acids, boric for the first and succinic for the second – an organic compound which plays a role in cellular metabolism.
This mixture stores – at around 165°C – an energy of 394 joules per gram, approximately double what industrial materials offer in this temperature range – enough to heat around a hundred grams of water by 1°C. In addition, the mixture underwent a thousand heating/cooling cycles without any notable degradation in its performance, show work published in Nature on December 18.
