First half pre-tax losses at CAP-XX rose to A$1.9m - up from A$1.3m last time.
Total revenue for the six months to the end of December fell by 18% to A$1.35m.
The group said this was largely due to a disruption of supply after a process change at a key raw materials supplier.
It aid this issue had now been fully rectified and additional measures had been implemented at the supplier and at CAP-XX to prevent any reoccurrence.
The group said it had received a significantly higher number of enquiries for very large volumes of small prismatic supercapacitors, including its Thinline products and the Internet of Things remained the biggest source of these new opportunities.
it also saw encouraging levels of large scale sales opportunities for automotive supercapacitors, although the lead time for these opportunities to convert into sales was long.
