Cool batteries are good batteries

'As consumers, we are all-too-familiar with the daily chore of charging our smartphones or tablet. With increasing emphasis on greener technologies such as electric vehicles and renewable energy generation, battery technology becomes more important.

Classic lithium-ion (Li-ion) batteries are currently the most common, storing energy in chemical form. The problem with these is their temperature sensitivity. During repeated cycles of charging and discharging, the chemical reaction that drives the battery creates heat which affects its storage capacity and lifetime. Not only that, but these high temperatures present a real health and safety concern. Thermal runaway, where a battery creates a vicious cycle of heat generation, can lead to catastrophic failure. Remember the Galaxy Note 7 explosions? So how can we cool batteries down?

NEVAC (short for Novel EVAporative Cooled battery technology) solves this problem with a novel cooling strategy. The research project, led by Dr Robert Camilleri (UM) in collaboration with industrial partner Abertax Kemtronics, is funded by the Malta Council for Science and Technology Fusion: The R&I Technology Development Programme 2017.'
