Malaysia is one of the major producers and exporters of Crude Palm Oil, producing roughly 31% of world\’s production. Over 5 million hectares are being utilized and the Palm Oil industry contributes 8% of Malaysia\’s Gross National Income. As such, it is one of the critical industries for the livelihood of Malaysians. This industry also leaves behind to the tune of 100 million dry tons of Oil Palm Waste.
One of the key challenges facing any battery chemistry is energy density. How does one increase energy density without compromising on safety? While this is important for all batteries in general, this is even more important for micro batteries that are to power critical sensors and implanted device.
The scientific community and UN have come up with a recommendation of no new Carbon emissions added beyond year 2050. How much can we emit until that time?
What if there is a blue print to help reverse global climate change? What can we do in our day to day life to help reduce carbon emissions? While these questions may prove to be at the scale of solving world hunger, Paul Hawken and team had taken a shot at answering these questions.
Be it an energy generating cell or an energy consuming cell, efficiency of an electrochemical cell has traditionally been looked at as a product of voltage efficiency and current efficiency. Voltage efficiency takes care of the impact of ohmic losses in electrode and electrolyte, polarization losses at the electrode due to charge transfer reaction and polarization losses due to mass transfer limitations. Current efficiency takes care of the impact of parasitic reactions and the effective utilization of reactants. Can there be additional energy loss leading to efficiency loss that is not captured in either via voltage or via current efficiency?
