Description
Summary:Until now, commonly used batteries included the nickel-cadmium (NiCd) and nickel-metal hydride (NiMH) chemistries typical in cell phones, and even the newer lithium-ion ([Li]-ion) batteries, which are used to power higher-end devices. When LiPBs become available in high volume, the chemistry is expected to challenge and replace NiMH and Li-ion batteries as the preferred power source for portable electronic devices. LiPB technology delivers the best energy density available for rechargeable batteries. LiPB and Li-ion batteries have similar characteristics. Both offer power in the 3- to 4.2-V range, compared with 1.2 to 1.5 V for NiCd and NiMH cells. LiPB technology emulates the life-cycle benefits of the Li-ion chemistry, providing 500+ charge/discharge cycles with no memory effect. Furthermore, the voltage, energy density, and cost make LiPB the leading contender for future electric vehicles.
