Introduction to
PowerGenix
NiZn batteries
1/35
• Founded in 2000 to develop a safe, high performance, and cost effective
alternative to currently available sealed rechargeable batteries such as:
• Lead Acid, NiCd, NiMH, and Lithium Ion
• Headquarters in San Diego, CA
• Manufacturing in China (800K daily battery capacity)
• Certifications include UL, CE, ISO9001:2000, ISO14001 and RBRC
• Worldwide employees: 100
• Initial focus on military applications, HEV, cordless tools, and AA/AAA consumer
batteries
• Highly experienced management team
• 100+ years of combined battery experience
Who is PowerGenix?
PowerGenix is an environmentally friendly battery company
that has developed and patented a Nickel Zinc (NiZN) battery
solution that delivers optimal power for various applications.
The best consumer rechargeable battery system !
Benefits:
• Only true rechargeable alternative for 1.5V single-use batteries due to higher voltage than traditional rechargeable batteries
• 1.6 volts optimizes power in applications
• NiZn 1.6 volts delivers superior power output, like lithium primary, rechargeable though !
• The highest power density rechargeable system available on the market today.
• Greenest rechargeable battery system existing. 100% recyclable (contrary to e.g. NiMH and Lithium that hold compounds that cannot be recycled). Contributes to an improved environmental impact.
• Much better performance in extreme temperatures compared to NiMH. Ideal outdoor power product e.g. for GPS etc.
• Pays back in only 5 charges*
• Stays charged longer**
* reference: Duracell Plus at •€ 4,99
** compared to regular NiMH batteries at room temperature
PowerGenix: Competitive Advantage
• PowerGenix NiZn offers a better rechargeable solution than the Energizer disposable lithium product for power hungry electronic devices
• NiZn 1.6 volts delivers superior power output, like lithium
• Energizer lithium costs around $10.00 and can only be used once. Save money over time with NiZn and recharge over hundreds times!
• Energizer lithium, like alkaline, is disposable and will end up in the landfill…..not a “green” solution.
• PowerGenix NiZn AA batteries are 1.6 volts versus NiMH AA batteries that are 1.2 volts
• The higher 1.6 voltage profile of NiZn delivers a shot of power to devices and provides longer usage time resulting into e.g. more pictures with digital cameras, brighter light in flashlights, faster reaction in game controllers, more playtime in music players, longer runtimes in general purpose devices etc.
• Even though NiMH may be high(er) capacity, because most devices have a 1.0v cut-off, not all the power in the cell is even being utilized
• NiZn is more environmentally friendly than NiMH
• 100% of all NiZn constituents are recyclable (vs only 70% of a NiMHcell)
• Works longer, needs less charges

PowerGenix has perfected the
use of NiZn chemistry in a AA
and AAA battery format to
deliver a superior power product
for use in consumer electronic
devices.
Multiple Performance Advantages
• Ni-Zn is 25% smaller because of 1.6V (versus 1.2V)
• Ni-Zn is 30% lighter: Lighter zinc electrode + Less cells
and connectors for pack packaging
• Ni-Zn is >20% more powerful: Lower cell Ω and 25%
less cells in pack
• Cost competitive with Ni-Cd, >25% less than Ni-MH
• Environmentally friendly: No Cd, Pb, As, or Hg
vs. Ni-Cd and Ni-MH
6/28
Multiple Performance Advantages
• Ni-Zn has 40% more power density (1,700 W/Kg vs. 1,200 W/Kg, continuous)
• Ni-Zn is cost effective ($0.35-$.40/Wh vs. $.60-70/Wh)
• Ni-Zn charger is simpler and is 50% less cost of a Li-ion charger
• Ni-Zn packs have 18% less energy density than Li-ion at 10 C rate
discharge (45 Wh/Kg vs. 55 Wh/Kg)
• Ni-Zn requires no power management or protection electronics
• Li-ion batteries are classified as “hazardous material” in quantities
above 96Wh adding transportation and logistics costs
• Completely safe: Ni-Zn has an aqueous (vs. organic) electrolyte
• All battery constituents will not burn
vs. Lithium-ion
