Exploding Li-ion batteries aside, one other problem with such batteries is the eventual degradation of their performance. No matter what anyone tells you, the performance of such batteries drops over time. On Wednesday Hewlett-Packard and Boston-Power announced an upcoming option for HP laptops: a battery designed to last for at least three years without performance degradation.

Volkswagen AG is seeking partners to cooperate on battery for auto power supply in China, Volkswagen China vice president Xu Jian said in an interview at the CEIBS 6th Annual China Automotive Industry Forum held in Shanghai on Nov. 6-7.

Top hydrogen-absorbing metal alloy sixty percent lighter than battery

How much battery life do I really have left? Texas Instruments Incorporated (TI) (NYSE: TXN) answers the question by introducing its system-side fuel gauge integrated circuit (IC) with Impedance TrackTM technology for smart phones and other handhelds. The 2.5 mm x 4 mm gauge predicts battery life with 99-percent accuracy to extend run-time, protect data and provide a better user experience for mobile handheld users.

Vishay Intertechnology, Inc. announced the industry’s first power MOSFETs with on-resistance ratings at a 1.2-V gate-to-source voltage, a move that will help designers simplify power management circuitry while extending battery run times in portable electronic systems.
