Researchers at Honda, NASA, and Caltech say they have created a prototype of a fluoride battery that could have 10 times the energy density of a lithium-ion battery. There are just a few minor issues to work out, like how to keep the electrodes from dissolving.
Researchers in the UK are working on new supercapacitors they claim can recharge in 10 minutes and power an electric vehicle for up to 350 miles.
Editor’s Note: Four great comments (well, even more than that) highlight why energy density parity with gasoline really misses some critical points. I’m highlighting them here before the article. Adrian notes: Yes, thanks to relative efficiency differences and much simpler support systems, batteries only need to be about 30% as energy-dense as … [continued]
Ah, ExxonMobil decided to go and play the energy density card in a recent commercial, comparing the energy density in a gallon of gas to electricity in a somewhat “clever” way. One thing left out of the equation, however, is that, “while gasoline does have a high energy density, internal … [continued]
One thing I find very odd about the world is that even today when solar panels are being installed from Canada to Tasmania and powering everything from laptops to fish tank filters to cars, there are still people who appear to wake up in the morning and decide that their … [continued]
Cabot has developed a graphene-based additive called LITX™ G700 to improve the energy density of lithium-ion batteries. LITX™ G700 is a conductive graphene-based additive that is to improve conductivity and achieve a high energy density in lithium-ion batteries at “ultra-low loadings” in comparison to conventional additives. Lower volume additives offer the advantage … [continued]
Surface-mediated cells (SMC,) from Angstron Materials Inc., offer us the advantage of increasing both power and energy densities.
Leyden Energy constructed a new type of lithium-ion battery that it claims has an energy density of 225 Wh/kg, nearly twice that of typical lithium-ion batteries, which is usually less than 120 Wh/kg.
