Researchers claim that an Efficient battery for electric cars, can potentially be charged up to 60% in just 6 minutes.
A battery that uses copper and copper nanowires can charge electric vehicles batteries at 60% level in just 6 minutes, without affecting its energy storage. This will allow drivers to travel longer without waiting long for their EVs to charge.
Lithium-ion is the most commonly used battery. It uses binding agents to stick its particles together to form a solid structure. This can create a thick battery fluid with a random distribution of particles, slowing down charging time. In order to speed it up, particles of thinner battery fluids are ordered, but they tend to store less energy.
Yao Hongbin, together with his colleagues at the University of Science and Technology of China in Hefei, designed a lithium-ion battery with a structured anode. They organized the particles according to particle size and the number of gaps between particles.
To organize the particles, the group coated them with copper and mixed them with copper nanowires. It was then heated, cooled, and compressed, setting the ordered structure.
Yao Hongbin stated, “In our design, we control the whole density in the electrode. We use a higher porosity in the top [of the anode] but lower porosity in the bottom, so that the average porosity has a normal value.” NewScientist reported.
Their battery charged at 60% in 6 minutes and 80% in 11 minutes, maintaining high energy storage during their tests. However, they didn’t record time on 100% charge.
