In summary, we successfully resolved the “cathodic challenge” of aqueous electrolytes by designing a unique inhomogeneous electrolyte additive approach to minimize competitive water reduction on graphite or Li-metal surfaces during the interphase formation.
Upon reductive decomposition during the first charging process, the highly fluorinated additive forms a protective interphase that enables the reversible cycling of both graphite and Li-metal anodes in aqueous electrolytes.
IceBattery storage is a commercially-proven and reliable technology. Each ice battery is designed to last 20 years and requires minimal maintenance.
Over heard about the IceBattery?
California-based Ice Energy inked an agreement, in June, making the Melbourne-based Apricus the exclusive distributor of all its thermal energy storage products in Australia, covering all market segments, including utilities, commercial and industrial, and residential.
IceBattery energy storage technology could dramatically change the way people cool their homes in summer – potentially cutting household peak power consumption by up to 95% – is poised to take on the Australian market, through a distribution deal with local solar hot water company Apricus.
By modifying the structures of molecules used in the positive and negative electrolyte solutions, and making them water soluble, the Harvard team was able to engineer a battery that loses only one percent of its capacity per 1000 cycles.
Harvard scientists have developed a new flow battery which stores energy in liquid, works 10 years without energy loss and is much safer than lithium-ion batteries.
After a few years of heavy use, most lithium-ion batteries suddenly loose a lot of storage capacity. You surely recognize this from your smartphone, but that’s also a problem for energy storage which should last a very long time to store solar energy. Scientists at Harvard University have found a possible solution.
The new technology promises a battery definitely lasting ten years without losing much capacity. The solution is applied to a so-called flow-battery. The flow battery stores energy in organic molecules dissolved in neutral pH water. This new chemistry allows for a non-toxic, non-corrosive battery with an exceptionally long lifetime and offers the potential to significantly decrease the costs of production.
Festivals encourage the donation of urine. It could be also used for batteries according to Standford University
Researchers at Stanford University have developed an inexpensive battery for renewable energy. This is done by making use of urea, a substance which is to be found in fertilizers and urine. Isn’t this great news?
SolarCar Stella completed and won a six-day, 3,000-kilometer race from Darwin to Adelaide across the Australian outback, with an average speed of 67 km/h and with three people on board. The car also achieved a top speed of 120 km/h with a full load of four people, demonstrating the horsepower of this solar-powered vehicle.
Atlas Technologies – the startup of former students of the Technical University Eindhoven – explores whether the family car powered by solar energy, could be a commercial success.
During their study, the former students designed the solar family cars Stella and Stella Lux.
These solar-powered cars won in 2013 and 2015, the World Solar Challenge, a race for solar cars. Read More
If this large-scale storage of renewable energy in liquid ammonia succeeds, communities can cover long low wind and solar energy periods
The Battolyser, which will be used as a super battery in a gas power plant, is becoming a reality.
For the first time, TU Delft researchers led by Prof. Fokko Mulder have produced an integrated battery electrolysis system – known as a ‘battolyser’ – that can not only store or supply electricity efficiently as a battery but can also split water into hydrogen and oxygen using electrolysis.

In Stephentown, New York, Beacon Power has build a 20MW / 5MWh plant consisting 200 carbon fiber FlyWheels. These FlyWheels make between 3000 and 5000 cycles per year through their input in the frequency regulation market.
Power Storage: The world does have a lot of options but its still expensive.
In order to manage supply and demand our renewables, we need to store the electricity when the wind is blowing hard and the sun shines brighter than there is demand.
For instance, Berkeley wind energy experts suggest a likely average cost reduction of between 24% to 30% by 2030 and 35% to 41% by 2050 across the three wind applications studied — onshore wind, fixed-bottom offshore wind, and floating offshore wind.
There is a further 10% chance that cost reductions could be more than 40% by 2030 and more than 50% by 2050. BetterWorldSolutions offers you a number of actual, technically available options. Read More
Vattenfall: Our stated goal is to integrate this battery storage facility into the energy system and to give a large number of similar small local facilities access to the market through electricity trading
2nd Life project with used BMW batteries for balancing the grid. Vattenfall, BMW and Bosch test electricity storage with repurposed EV batteries in Hamburg.
2,600 used battery modules from over 100 electric vehicles are being merged to form a large electricity storage facility in Hamburg
The stored energy is available within seconds and can help to keep the electricity grid stable
Cordelia Thielitz, General Manager Bosch Energy Storage Solutions: Electricity storage systems are a key success factor for the new energy landscape.
V-Storage started a pilot using old batteries from busses as an energy storage system. The ‘old’ batteries are placed in a large container. They intent to use the stored energy to electrify busses and to increase the Grid Balance. The pilot will start in January 2017.
In four or five years, the batteries in the roughly one and a quarter million EVs currently on the road are going to start to wane. EV owners will either replace them, or replace the cars entirely.
That means we’ll have a lot of used batteries (with plenty of life left in them) but which are no longer suitable for EVs. What to do?
One possibility is repurposing them to serve as grid-connected energy storage.
Storage is valuable to the grid for many reasons, including its ability to smooth out fluctuations in supply, allowing for more integration of variable renewable energy. Read More
Eaton and Nissan said that, unlike Powerwall, xStorage will include professional installation and all requisite extras, such as cables.
Nissan and Eaton make home energy storage reliable and affordable to everyone with ‘xStorage’. Providing a sustainable ‘second life’ for Nissan’s electric vehicle (EV) batteries after their first life in cars is over.
The partners are collaborating to unveil a new residential energy storage unit. They intent to design the most affordable and reliable home power storage system for households. Read More
The heat is held in the salt, and the chemical reaction that trapped it there is reversed to release the heat again when it is needed. ‘It’s all about hydration and dehydration, or wetting and drying salt.
