Our Next Energy (ONE), a Michigan-based energy storage company, has unveiled a very interesting anode-free lithium-ion battery cell, with an exceptionally high energy density. The company claims that ...

In 2020, Tesla announced a breakthrough battery that would be much cheaper to produce while offering higher energy density thanks to new technologies like dry cathode coating and silicone anode.

In March, I used Amprius silicon anode cells as an example of how far lithium-ion cells were from mature battery technologies. In other words, a cell with twice as much gravimetric energy density as ...

Cathodes play a dominant role in defining cell energy density, and also make up a significant proportion of cell costs, due to the use of high-cost metals such as cobalt, nickel and lithium. Standard ...
