Scientists at the Zentrum für Sonnenenergie- und Wasserstoff-Forschung Baden-Württemberg (ZSW) (Center for Solar Energy and Hydrogen Research Baden-Württemberg) have developed Li-ion batteries that have already demonstrated a very high cycle life of more than 10,000 full cycles with retention of more than 85% of original capacity.
Yuriy Mikhaylik, Sion Power’s Director of Materials, is presenting details on this performance in an invited presentation at the ECS meeting in Honolulu this week. Sion’s roadmap to high energy density batteries. This approach addresses the safety and cycle life problems that have historically plagued lithium-metal electrodes.
Alcoa and Israel-based Phinergy have entered into a joint development agreement to develop further Phinergy ’s aluminum-air batteries. Aluminium–air cells are high-energy density primary (non-rechargeable) batteries originally developed in the 1960s. kWh/kg of Al—second only to the Li-air battery (13.0 Earlier post.).
NEC Corporation has developed a prototype next-generation manganese lithium-ion battery featuring cathodes that support higher voltage operations (4.5V The new cathode and electrolyte solution improve battery energy density by approximately 30%. Honolulu PRiME 2012. WO/2012/127717: Secondary Battery. Earlier post.)
Nissan provided a list of the top 15 markets in the US for the Nissan LEAF battery-electric vehicle. Another three are on the West Coast and in Hawaii: Seattle (4), Portland (5), and Honolulu (6). Honolulu, with 26 quick chargers, has one of densest charging grids in the US. Electric (Battery) Sales' Earlier post.)
High voltage lithium-ion battery prototype. NEC Corporation has developed a prototype next-generation manganese lithium-ion battery featuring cathodes that support higher voltage operations (4.5V These developments could help increase the range of electric vehicles in the future while reducing the weight of the batteries.
One of the major issues hobbling the commercialization of high energy-density lithium-sulfur batteries is the “polysulfide shuttle”—the shuttling of polysulfide ions between the cathode and anode. The polysulfide shuttle is a major technical issue that limits the electrical performance and cycle life of this type of battery.
The Air Line Pilots Association (ALPA) is calling on the US government to prohibit shipments of lithium-ion and lithium-metal batteries on passenger and all-cargo aircraft until new regulations are in place to ensure the safe transport of these materials.
Electrify America will invest in metro-based direct current fast charging (DCFC) stations in 18 metro areas, including these new metro areas in Cycle 2: Atlanta, Baltimore, Honolulu, Las Vegas and Phoenix. Bridgeport (CT) for the New York City market.
kWh lithium-ion battery pack. Using a standard 220V outlet, it takes three and a half hours to charge the battery from 20 to 80 percent of its capacity and less than eight hours to fully charge it. The battery can also be charged using a common household 110V outlet. Tags: Electric (Battery).
At the second-annual Climate Mayors Summit in Honolulu, Hawaii, 127 cities and 15 counties from across 38 states joined the Climate Mayors Electric Vehicle Purchasing Collaborative, and committed to purchasing more than 2,100 electric vehicles by the end of 2020.
In the United States, the LEAF is among the top 10 vehicles sold in San Francisco, Seattle and Honolulu. Electric (Battery) Sales' The top markets for Nissan LEAF are the United States with about 30,000 units, Japan with 28,000 units, and Europe with 12,000 units. In Norway, the LEAF is one of the top 10 vehicles sold.
GE and Better Place have formed a technology and financing partnership to accelerate the global deployment of electric vehicle infrastructure through collaboration in four key areas: standards-based technology development; battery financing; joint fleet electrification programs; and consumer awareness.
Integrated at US Hybrid’s Honolulu facility, the 25-passenger shuttle bus utilizes a 30 kW fuel cell fueled by a 20 kg hydrogen storage and delivery system. The fuel cell and 28 kWh lithium-ion battery pack power the vehicle’s 200 kW powertrain, air conditioning, and auxiliary systems.
Lithium-sulfur batteries are of great interest for electromobility applications, among others, due to their high specific energy and relatively low cost, but are challenged by significant capacity decay over cycling. The interplay between anode and cathode is the critical factor determining the performance and lifespan of a battery.
FlyZero compared zero-carbon emission energy sources such as batteries, hydrogen and ammonia; the team concluded that green liquid hydrogen is the most viable, able to power large aircraft utilizing fuel cell, gas turbine and hybrid systems.
Proterra battery-electric buses will contribute to CLT’s sustainability goals. By planning for scale now, CLT can utilize the charging infrastructure for a range of battery-electric powered service vehicles in the future. Proterra Catalyst vehicles have no tailpipe emissions and decrease dependency on fossil fuels.
Better Place has started its initial deployment of EV infrastructure in Hawaii, with the launch of a project to incorporate its electric-vehicle infrastructure in Honolulu, in partnership with Kyo-ya Hotels & Resorts’ Sheraton Waikiki Resort and Hawaiian Electric Company. Kyo-ya will operate two of the electric vehicles.
Details of the technology are being presented this week at the IEEE Radio Frequency Integrated Circuits Symposium (RFIC) 201 in Honolulu, Hawaii. Given the fact that even cars are becoming battery-operated, it is imperative that these circuits be low-power. The W-band covers the frequencies used by automotive radars.
These typically range from $1,000 to $3,000 per battery electric vehicle in most states, and they are typically about half as much for plug-in hybrid vehicles due to their lesser all-electric driving capability. Four of the areas—Portland, San Jose, San Francisco, and Santa Cruz—have 20 or more actions in place.
The vast majority of the funded projects are for battery-electric buses and infrastructure; two projects are receiving a total of $3.2 The funding is for the incremental cost of a battery electric bus over a CNG bus and leverages federal, state, local utilities and local match to purchase the battery electric buses for service expansion.
These include hydrogen fuel cells, battery electric engines, and related infrastructure investments such as charging stations. Honolulu Department of Transportation Services. The Owensboro Transit System will receive funds to purchase an electric battery bus and a charging station to maintain a state of good repair. Description.
However, technical challenges with regard to battery performance due to charge and discharge cycles need further investigation and remediation.” A Dispatchable Distribution Feeder for Peak Load Reduction and Wind Farming (Honolulu, HI) - $5,548,585. Smart Grid System Report Annex A.
The island gets on average nearly 3,000 hours of sunshine per year, putting it on a par with Honolulu and Brisbane, Australia. Rooftop solar power totaling about 200 kilowatts, complemented by 1 megawatt-hour of battery storage , supplies electricity to 14 businesses in Adjuntas.
