Technology Forecasting withScience Indicators: TheCaseofLaptopBattery Futures

This paperforecasts technological changefor laptopbatteries. Laptopperformance has incrementally improved andpowerdemandhasincreased requiring batteries withhigher energydensities. Themostpromising technology to replacelaptopbatteries emergingtodayisthefuel-cell. Currently Li-ion batteries powerlaptop ormobile computers. Li-ion batteries withtheir highchargepotentials promise tobe thebattery withthehighest energydensity. Theproblem isthat thereiscurrently atechnical performance gapinthelength of timethatabattery cankeepalaptop functioning. I.INTRODUCTION
