KAUST uses laser pulses to boost performance of MXene electrode

Green Car Congress

Graphite contains flat layers of carbon atoms, and during battery charging, lithium atoms are stored between these layers in a process called intercalation. The researchers made an anode from the laser-scribed material and tested it in a lithium-ion battery over 1000 charge-discharge cycles.

Thermal Energy Storage Is No Longer Just Hot Air

Cars That Think

The company is building these shipping container systems, which work like giant batteries that store energy as heat and pressurized air , rather than a chemical reaction (Cheesecake’s name is derived from a nerdy acronym for their technology.) Recent years have seen the construction of large lithium-ion battery farms that do just that.

Swedish researchers explore use of carbon fiber as active electrode in structural battery for electric vehicles

Green Car Congress

Woven carbon fiber can act as an electrode for lithium ion batteries. Researchers in Sweden are exploring the use of carbon fiber as an active electrode in a multifunctional structural Li-ion battery in an electric car; i.e., electrical storage is incorporated into the body of the car.
