RPI researchers develop safe, long-cycling Li-metal rechargeable battery electrode; demonstrate Li-carbon battery

Green Car Congress

Researchers at Rensselaer Polytechnic Institute have developed a safe, extended cycling lithium-metal electrode for rechargeable Li-ion batteries by entrapping lithium metal within a porous graphene network (Li-PGN). In this regard this concept is no different from a conventional Li-ion battery. O 2 and Li 3 V 1.98 Mukherjee et al.

Researchers develop rechargeable hybrid-seawater fuel cell; highly energy density, stable cycling

Green Car Congress

Hard carbon and Sn-C nanocomposite electrodes were successfully applied as anode materials, yielding highly stable cycling performance and reversible capacities exceeding 110?mAh?g Sodium can serve as an alternative to lithium in rechargeable batteries as the reversible storage mechanisms for sodium ions are very similar (e.g.,

BMW shows i Pedelec Concept e-bike

Green Car Congress

Coinciding with the opening of the first BMW i Store on London’s Park Lane, the BMW Group presented the new BMW i Pedelec (Pedal Electric Cycle) Concept—a custom-made complement to the BMW i3 Concept ( earlier post ). The compact bicycle can be folded up quickly; the trunk of the BMW i3 Concept has room for two.

Nano-vault architecture alleviates stress in Si-based anodes for Li-ion batteries

Green Car Congress

GPa) is ascribed to arch action, a well-known civil engineering concept. Traditionally, graphite is used for the anode of a lithium-ion battery, but this carbon material has major limitations. But in graphite anodes, six atoms of carbon are needed to store one lithium ion, so the energy density of these batteries is low.

Researchers demonstrate concept desalination battery

Green Car Congress

A team from Stanford University and Ruhr-Universität Bochum have demonstrated the novel concept of a “desalination battery” that uses an electrical energy input to extract sodium and chloride ions from seawater and to generate fresh water. The electrodes are then recharged in this solution, releasing ions and creating brine.

Volvo Car Group testing lightweight structural energy storage material applied in trunk lid and plenum cover

Green Car Congress

A composite blend of carbon fibers and polymer resin is being developed that can store and charge more energy faster than conventional batteries can. The material combines carbon fibers and a polymer resin, creating a very advanced nanomaterial, and structural supercapacitors. Close up of the trunk lid carbon fiber composite.
