Advanced gel polymer electrolyte for lithium-ion polymer batteries (Iowa State University)
"Currently, secondary cell batteries are widely used in portable electronics and hybrid and electric vehicles and limitedly for storage of wind and solar energy."
How Lithium-ion Batteries Work (How Stuff Works)
"A lithium-ion battery pack must have an on-board computer to manage the battery. This makes them even more expensive than they already are."
"If you completely discharge a lithium-ion battery, it is ruined."
Fundamental degradation mechanisms of layered oxide Li-ion battery cathode materials: Methodology, insights and novel approaches (Materials Science and Engineering: B)
"Degradation is mainly characterized by irreversible capacity loss (capacity fade) and voltage loss, i.e. increase in cell impedance, coupled to changes in kinetic and thermodynamic properties of involved materials and their interfaces"
Going solid-state could make batteries safer and longer-lasting (MIT)
"This solid-state electrolyte has other, unexpected side benefits: While conventional lithium-ion batteries do not perform well in extreme cold, and need to be preheated at temperatures below roughly minus 20 degrees Fahrenheit, the solid-electrolyte versions can still function at those frigid temperatures [...]"
