Contributing Editor David Kirk takes a look at the latest technology being deployed in battery systems and portable power provision for productions…
Lithium-ion batteries have dominated the portable power market for nearly 30 years and continue to do so. Summaries of their development to date can be seen on https://en.wikipedia.org/wiki/Lithium-ion_battery and https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7215417/.
Lithium-ion today faces competition from various alternative energy storage technologies, notably aluminum-graphite batteries, bio-electro-chemical batteries, graphene supercapacitors, hydrogen fuel cells, lithium-sulphur batteries, solid-state batteries, thin-film batteries and vanadium redox flow batteries. In a broadcast context, the most significant trend is towards smaller, lighter and more power-efficient production tools which in turn allow smaller batteries.
So what’s new since InBroadcast overviewed this category a year ago?
