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 ...

Microbial fuel cells, as they're called, have been around for more than 100 years. They work a little like a battery, with an anode, cathode and electrolyte – but rather than drawing electricity from ...

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 ...

Details of the "3D Silicon" silicon-anode Li-ion battery. What's behind Brakeflow, another advance that enables multiple parallel cell-to-busbar connection. Other companies involved in silicon-anode ...
