‘breathing’ battery to power future electric cars - battery power storage
Tokyo: Scientists are working on a new type of battery for gen-
The efficiency of the next electric vehicle may be three times that of the existing electric vehicle.
As electric vehicles become more popular, researchers at the University of Mie in Japan are beginning to find it difficult --
To introduce a new battery, the battery can extend the range of these cars far to the current limit.
The researchers, led by Professor Nobuyuki Imanishi, said the breathing battery could allow electric vehicles to travel more than 482 kilometers on a single charge.
Ordinary lithium
The maximum range allowed for ion power storage devices is about 160 kilometers. “Lithium-
The air battery is light in weight and provides a lot of electricity.
"Many people hope they will be used for electric vehicles one day," Imanishi said . ".
The main difference between lithium-Lithium ion and lithium
The air cell replaced the conventional cathode-
Key battery components involved in current flow-with air.
This makes rechargeable metal
The air battery is lighter than the commercial battery, and it is possible to pack more energy.
One of the main components that the researchers are working on is the electrolyte of the battery, which conducts electricity between electrodes.
There are currently four electrolyte designs, one of which involves water.
The advantage of this "water" design over other designs is that it protects lithium from the interaction of gases in the atmosphere and achieves a rapid response on air electrodes.
The team at Imanishi developed a layered approach to clip high conductivity polymer electrolyte and solid electrolyte between the lithium electrode and the aqueous solution.
The result is that a unit has twice the potential of packaging energy storage capacity, in units per watt hour (Wh/kg), as a lithium-ion battery.
"The actual energy density of our system is over 300 Wh/kg.
This contrasts with the energy density of commercial lithium
The much lower ion battery is only about 150 kWh/kg, "Imanishi said.
The battery shows great promise, the researchers say, with high conductivity of lithium ion and the ability to discharge and charge 100 times.
The researchers presented their findings at the National Conference and Expo of the American Chemical Society (ACS)in Dallas.
