Program Description: Hybrid lithium battery packs combine lithium metal primary cells with smaller lithium ion cells to power electronic devices that operate intermittently for long durations. These devices typically dissipate power in short bursts, separated by long intervals of exceptionally low standby power. Lithium metal primary cells hold typically three times the energy of alkaline or rechargeable lithium cells, but the cells that store the most energy often supply too little current to operate many devices. Hybrid cells solve this by including small rechargeable lithium ion cells that store enough energy to power the bursts. The hybrid cells then recharge slowly during standby intervals. The combination of these two into hybrid battery packs often substantially increases the efficiency of the pack, allowing devices to run longer.
