I recommend people read the article, it actually has some information. More info:
"The battery has an energy density of 24 Wh/kg, meaning approximately 20 percent capacity compared to comparable lithium-ion batteries currently available. But since the weight of the vehicles can be greatly reduced, less energy will be required to drive an electric car, for example"
"the researchers did not choose the materials to try and break records – rather, they wanted to investigate and understand the effects of material architecture and separator thickness." - this implies there may be a lot of room for improvement with this design.
- ThomPete 6y agothen the question becomes how are they solving for the increased heat.
- TheAdamAndChe 6y agoIn increased surface area-to-mass ratio would probably make this easier.
- ThomPete 6y agoWhich makes it heavier no?
- TheAdamAndChe 6y agoNo. A rectangular block of a typical battery has a much lower surface area-to-mass ratio than a tube, even if their weights are the same. It's why cooling fins on a CPU are long and skinny. Such length and skinniness makes heat dissipation much easier.
- ThomPete 6y agoBut if the energy density is higher wouldn't you need more material to cool down the area?
