Ann: Change of Director's Interest Notice - Copulos, page-10

welcome cool roe

i posted on 28/2/17 that Battery testing takes time & BKT is being thorough.

specifically, the 7/2/17 announcement refers to 'thermal purification' results & states BKT is targeting 'long term cycle' of 100 cycles. at 7/2/17, BKT announced 25 cycles, with 75 cycles to complete. it takes many hours to complete one cycle

MNS's presentations have testing up to 38 cycles

so BKT is going for 100 cycles


In 2016 Black Rock engaged a US accredited firm to commence spherical graphite and purification test work... by the Company’s proprietary, acid-free, environmentally benign carbothermal purification process to 99.99994 wt% C purity. Long term cycling of uncoated and coated graphite showing virtually no change in battery performance with 25 cycles completed to date of a 100+ cycle period. The key point of the uniform cycling test results is that the Mahenge SPG is remarkably stable and shows attributes that may result in longer LIB cycle life. Additional test work is ongoing on long-term cycling to prove this.
