CONTINUING TO DELIVER MINIMAL BATTERY DEGRADATION AT 125 CYCLES

Results from Figure 2 continue to demonstrate minimal increase in the measurable cycle degradation between the batteries made entirely of graphite (the red lines) and those incorporating Novacium's custom-engineered silicon-based material blend (the blue lines), between the 100 cycles and the 125 cycles, as expected. The Novacium non-optimized first generation of engineered silicon anodes material continue to deliver results within the range of comparable graphite batteries. These promising results have real world applications.

“The data generated during testing continues to provide the crucial information needed to develop an enhanced second generation of advanced silicon-based material, that we believe will allow us to deliver even better results,” added Dr. Kraiem. “This material is presently being utilized in the production of additional batches of 18650 batteries to be tested.”

ADVANCE SILICON-BASED ENGINEERED ANODES MATERIAL MARKET OPPORTUNITY

As pure graphite anodes have essentially achieved their maximum performance in terms of energy density [3], a trend in the lithium battery industry has been the introduction of small amounts (about 5%) of silicon oxide (SiOx) material into graphite composite electrodes. This basic SiOx material, primarily used in the fabrication of optical materials, sells for about US$15 per kg [4] and delivers less than optimal results.

While Silicon remains the most promising candidate that can drastically improve the anode performance (more than 10 times), its industrial application is still very limited due to unresolved issues related to volumetric expansion or due to the usage of very complex and highly expensive solutions.

The manufacture of an engineered silicon-based anode material, such as the Novacium product, will enable the battery industry to overcome these problems and increase battery capacity without significant degradation of the battery's lifetime. Presently the selling price of engineered silicon-based anode material is around US$75 to US$100 per kg [4]. The Si-C material made using CVD deposition of Silane material sells for about US$300 per kg [4], which is not feasible for massive industrial application.
