Mild and Full Hybrids
For mild and full hybrids, Nickel-Zinc (NiZn) offers the high power, cycle life and energy density necessary to meet the high torque demands of these vehicles at cost-effective levels.
A high performance, drop-in replacement for Nickel-Metal Hydride
NiZn batteries are a high performance and low-cost alternative to the Nickel-Metal Hydride (NiMH) batteries currently used in almost all mild and full HEVs. With superior energy density and power density compared to NiMH, NiZn reduces battery weight and size by 30 percent and does so at a 25 percent cost advantage over NiMH. These advantages are illustrated in the comparison below between the 1.3kWh NiMH pack in a current HEV and a NiZn replacement. The NiZn pack provides more power and equivalent hybrid fuel efficiency in a package one-third lighter than the NiMH pack.
A low-cost, safe alternative to Lithium-ion
Lithium-ion’s (Li-ion) high energy density makes it well suited for plug-in electric vehicles (PHEVs) and electric vehicles (EVs), which require large amounts of stored energy to travel long distances between charges. However, HEVs require a different type of battery – one with high power density, or the ability to charge and discharge large amounts of power quickly. Li-ion high-power batteries for HEVs are significantly more expensive than high-energy batteries for EVs. NiZn is an inherently high-power chemistry and can provide equal or greater power (W/kg) at half the cost of Li-ion HEV batteries. The cost advantage of NiZn is durable, based on the lower material costs of its constituent elements, includingcommodity metals in abundant supply and easily recyclable materials. In addition, the materials used in NiZn batteries are non-combustible and inherently safe — resulting in less expensive manufacturing processes, simpler pack integration and less complex and expensive safety/power control systems.
