Any newer holders wanting to learn more about the quality of Orom Cross graphite might like to read the RNS dated 30 October 2023. Partial quote below:
“ After purifying the material using high temperature (but no acid or alkaline treatment) to a level of 99.99 wt% C, AETC subjected it to spheroidisation and classification. The resultant graphite has a very impressive tap density (read 'energy density') of 1.1 g/cm3, with a surface area of 2/g. Both of these indicators highlight an extremely high grade end product.
The uncoated graphite was tested in the industry-standard CR2016 coin cells v. Li/Li+ counter electrode at C/10 charge-discharge rate. The material was seen to deliver very impressive reversible capacity of 367.58 mAh/g which is defined as "near theoretical" electrochemical performance, considering that theoretical capacity is 372 mAh, and hardly any graphite has been able to achieve this historically in practical applications. This indicator alone ranks Orom-Cross graphite as high as any other SPG product elsewhere.
The uncoated material was also surface-coated to form CSPG ("coated spheronised purified graphite"), which is the ultimate form of battery-ready graphite that goes into the anode. Application of surface coating makes batteries that use such graphite safer; additionally, graphite anodes which are composed of surface-coated graphite tend to have lower irreversible capacity loss, a key property linked to management of electrolyte levels inside an operating lithium-ion battery.
The coated material was put into batteries and subjected to short and long-term cycling. The carbon-coated version of this graphite displayed excellent electrochemical performance, with a reversible capacity loss and reversible capacity constituting near theoretical electrochemical behaviour which positions the material from Blencowe into the class of super-premium anode grade graphite for use in lithium-ion battery anodes.
The long-term cycling of this material has retained an excellent stability of performance characteristics as a function of cycle life, having scored a very low 1.39% degradation. Testwork suggests that Orom-Cross graphite can support 1,438 cycles while the United States ABC requirement for EV batteries is 1,000 charge-discharge cycles. Therefore, with nearly 50% additional cycles, the Orom-Cross material is again highlighting its premium quality and is ideally suited for application in the lithium-ion battery anodes.
It is worth noting that the non-spherical portion of Blencowe's graphite (which accounted for approximately 25.6% of feed into the AETC spheroidising process) generated expanded delaminated graphite and spheroidisation process rejects, which were formulated into the composition of alkaline, lead acid batteries and an electrically conductive can coating. In all instances, the non-spherical portion of Blencowe's material offered outstanding performance…”
