MIT researchers have engineered a new rechargeable, membrane-less hydrogen bromine laminar flow battery with high power density. In such a device, two liquids are pumped through a channel, undergoing electrochemical reactions between two electrodes to store or release energy. Credit: Braff et al.

They have some of the fastest charging speeds availabletoday at up to 350 kW (Hyper-Fast), depending on the charger. For example, at 350kW, capable EVs can recharge up to about 20 miles of driving range per minute of charging. The expansion at Baker also adds four new individual chargers, bringing the total to twelve.
Bosch is investing €400 million (US$455 million) per year in electromobility; part of that investment is researching batteries with twice the energy density at lower costs than availabletoday by 2020. Today’s lithium-ion batteries are superior in this respect, storing more than three times the amount of energy per kilogram.
IBM and its partners have launched a multi-year research initiative exploring rechargeable Li-air systems for transportation—The Battery 500 Project ( earlier post )—but are viewing it in terms of a multi-decade development cycle. Also on the list of five is the arrival of advanced batteries, including air batteries (e.g.,
Earlier BEVs had a range of around 100 miles on a single charge, but today’s models can comfortably stretch to 300 miles via a 60-100 kWh battery pack. However, since BEVs rely solely on the amount of stored electricity in their batteries, they require charging infrastructure to make long-distance travel possible.
Heat-Pipe PCM Based Cool Storage for Air-Cooled Systems The project team will develop a novel storage system that collects and stores heat rejected from a power plant condenser during the day until the heat waste can be more efficiently rejected during the night at lower ambient temperatures.

The pure electric vehicles, for reserve, must carry heavy and expensive batteries—which add expense as well as weight—and must have access to high-powered recharging stations [ 1 ]. Furthermore, even the older version PHEV can recharge at a slow rate using local solar, wind, water-derived or other net zero CO 2 fuel.
Also, besides giving you the ability to charge at night when most utility rates are lower, future vehicle-to-grid (V2G) technology may allow you to sell some of your stored energy back to the utilities. Currently, there are some industrial facilities that use battery swapping to replenish the energy stores of electric forklifts.
The hybrid models availabletoday use lead-acid ornickel-metal hydride batteries that are are proven, reliable, and fairlycheap, but their limited storage capacity means that the cars’ driving rangeusing electricity alone is short. Witha 60-mile range, most felt the need to recharge after 30 miles or so.
