For those tech minded the electrolyte is still Lithium Iron-Phosphate and carbon fibre electrodes.
This month, Sinonus appointed Markus Zetterström as its new CEO, responsible for commercializing carbon fibers that double as electrodes and structures. (EV frame/body)
The startup sums up its purpose as "multipurpose," pursuing materials that serve two or more functions in an effort to conserve overall resources in an EV, for instance, its carbon fiber battery system would presumably weigh the same as or less than traditional steel and aluminum structural components but with the advantage of storing its own power and eliminating the need for a large, heavy battery pack.
