On the global demands of high power, high electrochemical energy storage and conversion technologies, efforts of developing commercially-viable fuel cells (FC) greatly prevailed for several decades. However, during the recent 10 years or so, the FC developers one by one, have perished or suspended their effort, particularly for portable applications while the efforts of developing new electrode materials for lithium-ion batteries (LIB) and even new rechargeable battery chemistry are still flourishing strong due to the prospect of more ubiquitous applications not only in powering consumer electronics but also in EVs, HEVs and even Grid-scale power plants.
In this presentation, fuel cells and rechargeable batteries are compared, and on-going efforts in developing new battery chemistries are briefly mentioned. Some results from the research activities in the portable power at Duracell will be also discussed.
