Bendable batteries: flexible approach required
Sitting in on symposium T, it was time to find out more about mobile energy - specifically, batteries that can be bent.
Pritesh Hiralal from Cambridge University, UK, is part of a team working on all-solid thin-film batteries for portable applications, or as he phrased it - flexible batteries for flexible electronics.
Hiralal’s approach is to redesign a standard zinc-carbon cell layer-by-layer and the latest prototype features a combination of electrospun carbon fibre cloth, single-walled carbon nanotubes and ceramic nanoparticles.
There’s more work to be done, but the initial results are encouraging and show that the flexible cell is able to withstand several bending cycles.
