Researches developed EV batteries that store 6 times more charge than common onesĀ 

Electric Vehicles India

An international team of researchers led by Stanford University has developed rechargeable batteries that store the charge up to 6 times more than the normal currently available commercial ones. Non-rechargeable batteries can not be done and when it drains their chemistry cannot be restored.

European automotive and automotive battery industries call for extension of the exemption of lead-based batteries from the EU ELV Directive

Green Car Congress

This means lead-based batteries are essential in virtually all conventional ICE (internal combustion engine) vehicles, hybrid vehicles (mild, micro and Plug-in-HEV, PHEV) and full electric vehicles. At high voltages, lead-based batteries are so far limited by their more modest recharge and discharge power and capacity turnover.

Sulfurā€“TiO2 yolk-shell cathode for Li-sulfur battery shows best long-cycle performance so far

Green Car Congress

The advantage of the yolkā€“shell structure is the presence of the internal void space that can accommodate the large volumetric expansion of sulfur during lithiation, thus preserving the structural integrity of the shell and minimizing polysulfide dissolution and enabling the high capacity retention.
