the beguiling promise of john goodenough's new battery technology - li ion battery cell

Google's Eric announced a new fast this week.
Battery charging technology by John Goodno, inventor of lithium batteryDoctor, ion battery
Maria Braga and his research team at the College of Engineering at the University of Texas in Austin.
The new design uses glass electrolyte instead of liquid electrolyte, sodium instead of lithium, and the energy density may be three times that of lithiumion batteries.
These batteries are not that hot, charging faster and cheaper than lithium, which is also a real advantage.
But don't start thinking about this new battery in terms of renewable energy.
Power storage issues between transport or manual
Handheld devices and utilities
The scale storage system is very, very different. Utility-
Large-scale power storage is needed to handle the intermittent nature of these two generations (renewables)and demand (
Rapid changes in use throughout the business day).
These are not necessarily small, most promising utilities-
Scale battery including new vanadium battery
Very large flow battery, large capacity, very stable and longlasting.
But for other small-capacity applications such as transportation and smartphones, size is really important.
These charges must be small and dense, and the charge must last for a long time in order to be most useful.
Electricity is the most efficient fuel for transportation, 10 kilometers per gallon is equivalent to 40 miles, but the cost is about $1.
Electricity is also the cleanest transport fuel as long as it is made by non-
Source of fossil fuel
But we still have to charge them regularly in order to make it easier to travel long distances.
Therefore, the new solid of Goodno
State batteries are ideal for this use.
The range of the electric car is twice as high as it is now, which will put it into the gas field
Power cars are what these markets need to take off.
In addition, these solids
The glass electrolyte can be in-20°C (-4°F)
So this type of battery allows the car to work in sub-zero weather.
In fact, this design is the first one. solid-
State battery that can work perfectly in cold weather. Current Lithium
Ion batteries use liquid electrolyte to transmit lithium ion between the negative poles of the battery (anode)
And the front of the battery (cathode).
If the liquid battery is charged too fast, thin metal beard or branch crystals will form a winding in the liquid, causing a short circuit, causing an explosion and a fire. This new solid-
The state design depends on the glass electrolyte, not the liquid, and cannot form a branch crystal.
Li is mainly mining from South America and China, brines from the United States, which is much more expensive and less numerous than Na precipitated from sea water.
So these batteries are more earth.
Friendly, too.
So with the development of new battery technology, will this make electricity cheaper? No, it doesn’t.
It does give us more flexibility to use it more efficiently, but storage adds about 2 kWh/kWh from the cost of building a storage systemspan.
Storage, battery or other means of saving no energy in the utility sector
Because we don't throw away any energy.
We have a power grid that is complex enough that we can deal with intermittently, although it is annoying to have to add gas or hydro-power plants up and down as the wind disappears or the sky cloud is shrouded.
Storage is really good if you want to get out of the grid.
If you are challenged geographically, need emergency power, or have enough disposable income, you can play and you want to do so.
This is especially important given the increase in roof solar, as Google described this week for roof solar in the United States.
California is vigorously developing solar energy, so that most industry experts are worried about the impact of solar energy on the power grid in California and surrounding areas.
In addition to batteries, there are other technologies for storing intermittent energy, such as thermal energy storage.
However, the most widely used storage method is pumped storage, which uses excess power to pump water into the reservoir behind the dam.
Later, when the demand for energy is high, electricity is generated by releasing stored water through turbines in the dam.
At present, 99% of power grid storage uses pumped storage, but the deployment location of pumped storage is limited by geology and environment.
But Goodno's new battery design and V-
Mobile batteries offer a wide range of technologies, and as we move towards a future where more and more energy is powering more and more people, we need to innovate with as much energy as we can.
