Another attractive aspect of this technology is that lithium metal can be produced from salt solutions (e.g., In other words, energy from the sun can be “stored” in the metal, and then be used on demand by reacting the lithium in the fuel cell. Recharging the battery would be a matter of replacing the lithium metal cell.

NRC report concludes US LDVs could cut oil consumption and GHGs by 80% by 2050; reliance on plug-ins, biofuels and hydrogen; strong policies mandatory

Green Car Congress

However, even these costs are unlikely to create a mass market for BEVs, because a battery large enough for a 300-mile real-world range would still present significant weight and volume penalties and probably could not be recharged in much less than 30 minutes. BEVs and PHEVs are likely to use lithium-ion batteries for the foreseeable future.

DOE awards $54M to 13 projects for transformational manufacturing technologies and materials; top two awards go to carbon fiber materials and electrodes for next-gen batteries

Green Car Congress

The top two awards, one of $9 million to a project led by Dow Chemical, and one of $8.999 million to a project led by PolyPlus, will fund projects tackling, respectively, the manufacturing of low-cost carbon fibers and the manufacturing of electrodes for ultra-high-energy-density lithium-sulfur, lithium-seawater and lithium-air batteries.
