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.

CO2-neutral hydrogen storage with a bicarbonate/formate system

Green Car Congress

Most importantly, after full conversion of the formate, the bicarbonate solution may be recharged with hydrogen to close the cycle. Bicarbonates are a component of many natural stones and are also commonly used as baking powder or sherbet (sodium bicarbonate, NaHCO 3 ).

ASU team develops new solution for mitigating Li dendrite growth by tackling plating-induced residual stress

Green Car Congress

Lithium-metal batteries are among the most promising candidates for high-density energy storage technology, but uncontrolled lithium dendrite growth, which results in poor recharging capability and safety hazards, currently is hindering their commercial potential. Envision sugar cubes that contain a lot of small internal pores.
