The battery, which can be lowcost and reliable in terms of safety, provides another chemistry for post Li-ion batteries, they suggest, and with higher practical energy densities than Li-air systems for supporting applications including electric vehicles and large-scale grid energy storage. —Wang et al.
Vorbeck Materials , a startup company based in Jessup, Maryland, is using a Pacific Northwest National Laboratory (PNNL)-developed method for developing graphene for better lithiumair and lithium sulfur batteries.
The 19 projects, which include two lithium-air efforts, will leverage $7.3 million in cost-sharing by recipients for a total of $15.3 Two projects: developing a novel nickel-zinc battery that uses low-cost materials and technologies to improve the performance of ultra-capacitors. Murray, Jr., million in funding.
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.
The critical barrier to wider deployment of electric vehicles is the high cost and low energy of today’s batteries. This ARPA-E program seeks to develop a new generation of ultra-high energy density, low-cost battery technologies for long range plug-in hybrid and all-electric vehicles. A123 Systems, Rutgers University).
Carbon is seen as an attractive potential cathode material for aprotic (non-aqueous) Lithium-air batteries, which are themselves of great interest for applications such as in electric vehicles because of the cells’ high theoretical specific energy. Given the role of carbon as a possible porous positive electrode for nonaqueous Li?O
Ford is exploring a variety of “beyond Li-ion” solutions, including Lithium-sulfur, Lithium-air and solid-state lithium-ion batteries. A Li-air battery, with its air cathode, is a low-cost system, Anandan said. Solid-state use solid electrodes and a solid electrolyte material.
Vorbeck, a manufacturer and developer of applications using its proprietary graphene material ( earlier post ), optioned the technology for use in a graphene-based electrode for lithium-air and lithium-sulfur batteries. PEM fuel cells are primarily used for backup power.
For the longer term, (2017-2027) while “beyond Li-ion” battery chemistries such as lithium-sulfur, magnesium-ion, zinc-air, and lithium-air, offer the potential of significantly greater energy densities, breakthrough innovation will be required for these new battery technologies to enter the PEV market, according to DOE.

Advanced liquid electrolytes for lithium-ion cells under extreme conditions, such as extreme fast charging, and mechanical, thermal, or electrical abuse. Novel liquid electrolytes for lithium-sulfur cells that improve the overall stability and performance of these cells. Lithium-sulfur and lithium-air battery cell development.
BEVs and PHEVs are likely to use lithium-ion batteries for the foreseeable future. lithium-air) are being developed that would address some of the drawbacks of lithium-ion batteries, but their potential for commercialization by 2050 is highly uncertain, and they may have their own disadvantages.
All are counting on battery innovations to improve EV performance, drive down costs, and eliminate dependence on scarce materials. The ideal battery will be made of low-cost, plentiful materials that are lightweight and flexible enough to allow vehicle design innovations.
However, with regards to cost, lithium-sulfur batteries might be superior, if the additional components which might be needed to improve cycle-life and safety (diffusion barriers, etc.) can be realized at lowcost, the authors suggest. While the so-called post-LiBs, viz.,
