While many vehicles switch to electrical power, the storage of electricity becomes crucial. Scientists are continuing research to set up a battery at a lower cost, performing and environmentally friendly.
The most promising type of rechargeable battery is the "continuous flow" battery, such as that recently developed by Michael Aziz and Roy Gordon of Harvard University.
The system involves separate electrolytes in two compartments of different sizes. Unlike conventional batteries, it is enough to replace the electrolyte so that it recharges completely. However, this operation leads to a loss of efficiency due to the corrosivity and toxicity of the solutions. As the system involves pumps and a storage tank, the cost of maintenance also becomes important.
But the two researchers at Stanford have managed to overcome this problem by designing new, more neutral electrolytes. The solutions allowed to reach the 1000 cycles without losing more than 1% of the capacity of the device. In other words, the battery will last 10 years with minimal maintenance.
