2 Wildcat s Value Proposition Wildcat uses unique high throughput technology to accelerate battery R&D for others Projects include new or improved cathodes, anodes, electrolytes, and binders Wildcat s value proposition is to accelerate time to market for new cell technologies and to reduce R&D costs NAATBatt ET Summit 2

3 Business Model Accelerate battery materials development for others Sale or license of new battery materials intellectual property Wildcat customers include material suppliers, cell makers, and OEM s Gov t Grants, National Labs Material Suppliers Cell Makers OEM s Wildcat accelerates battery materials development throughout the supply chain NAATBatt ET Summit 3

4 Wildcat IP Available for Partnering Name Description TRL CM1 CM2 CM3 CM4 A novel cobalt phosphate-based cathode material with potential for superior energy density and comparable safety relative to LiFePO 4. A method of modifying carbon-fluoride cathodes to improve voltage (+300 mv), rate capability (20%), voltage delay, and power. A novel, spinel-based oxide cathode with capacity >250 mah/g, low irreversible capacity, good rate performance & cycle life, and no voltage fade. Copper fluoride cathode material with potential for 2x the energy density of today s best NMC based cells. Wildcat has demonstrated cycle life of 20 cycles to 80% capacity in full cells. TRL 4 TRL 4 TRL 2 TRL 3 EM1 Electrolyte additives that improve stability at high voltages and high temperatures SuperFilm EM4 EM5 Film-forming cores and functional additives for electrolytes that increase cycle life, columbic efficiency and thermal stability of lithium-ion batteries. Non-carbonate electrolyte solutions for use with silicon anodes (funded in part by the U.S. Department of Energy) Wide temperature range electrolytes offering improved cycle life, developed specifically for start-stop vehicle applications TRL 4 TRL 3 TRL 3 EM6 Gas reducing electrolyte additive combinations for use with higher voltage cathode cells.

5 Wildcat s CM1 Discovery A doped lithium cobalt phosphate (LCP) cathode Patented composition, owned entirely by Wildcat High throughput result of synthesis and screening of more than 3,000 unique compositions Operates at 4.75V, with upper cut-off of 4.85V Successfully scaled to 1kg batches Compatible high voltage electrolyte additive also discovered that enables full cell cycling to >1,000 cycles CM1 Voltage Profile (4.9V) NAATBatt ET Summit 5

6 Wildcat s CM1 Discovery An attractive higher energy alternative to LFP, offering and additional 30% more gravimetric energy Higher voltage offers ability to eliminate cells per pack, potentially enabling lighter and cheaper military batteries Attractive for high power applications requiring more energy (e.g. power tools, e-cigarettes) NAATBatt ET Summit 6

7 Wildcat s EM5 Discovery Optimized electrolyte formulations that offer improved performance at both low and high temperatures LT ASI and HT Stability Patent-pending solution, co-owned by Wildcat and a cell-maker High throughput result of screening over electrolyte in over 6,000 cells Developed for NMC//graphite and NMC/LTO cells, but believed to be broadly useful with further optimization Additive Screening Solvent Screening Combination & Optimization NAATBatt ET Summit 7

8 Wildcat s EM5 Discovery Results validated in customer pouch cells, with great correlation Multiple solutions identified that improve both low and high temperature ASI Developed specifically for start-stop vehicle applications Useful for other wide temperature applications, including electronics and military Improvement No change Worse Electrolyte Cy1 Cap.
