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

Green Car Congress

New research conducted by the Okinawa Institute of Science and Technology Graduate University (OIST) has identified a specific building block that improves the anode in lithium-ion batteries. GPa) is ascribed to arch action, a well-known civil engineering concept. The resulting maximisation of measured elastic modulus (~120?GPa)

Stanford study finds charging Li-ion cells at different rates boosts the lifetimes of EV battery packs

Green Car Congress

Stanford University researchers have devised a new way to make lithium-ion battery packs last longer and suffer less deterioration from fast charging. It was later explained that the million-mile battery concept was not really a new chemistry, but just a way to operate the battery by not making it use the full charge range.

Lamborghini presents super sports V12 hybrid HPEV Revuelto

Green Car Congress

The three electric motors are powered by a lithium-ion high specific power (4500 W/kg) battery pack that also supports a fully-electric drive mode. The design concept underlying the development of the new monofuselage is based on the maximum integration between components.

Rechargeable membrane-less hydrogen bromine flow battery shows high power density

Green Car Congress

MIT researchers have engineered a new rechargeable, membrane-less hydrogen bromine laminar flow battery with high power density. Laminar flow batteries—which rely on diffusion to separate reactants—eliminate the need for an ion-exchange membrane. Credit: Braff et al. Click to enlarge. —Braff et al.

New Lithium rechargeable semi-solid flow cell offers energy densities an order of magnitude greater than previous flow batteries; possible applications in transportation and grid-scale storage

Green Car Congress

Scheme of the semi-solid flow cell (SSFC) system using flowing lithium-ion cathode and anode suspensions. In contrast to previous flow batteries, the SSFC stores energy in suspensions of solid storage compounds to and from which charge transfer is accomplished via dilute yet percolating networks of nanoscale conductors.

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). They then looked at the interaction of elemental lithium with such defect sites in the graphene.
