Toyota Develops Truffle-Like Cathode
French bus manufacturer Heuliez Bus has launched its first battery electric bus. The 12-meter GX 337 ELEC uses a 175 kW electric motor and is equipped for all-day use. It will go into testing under the French public transport operator RATP. Heuliez Bus has sold about 400 hybrid buses, and makes up about 24 percent of the French bus market.

Researchers at Toyota Research Institute of North America have created a nanostructured sulfur cathode that can help improve battery performance. Using a layer-by-layer self-assembly technique, the cathode features an ion-selective polymer membrane. The sulfur helps the battery achieve high rates of charge and discharge, while the membrane helps prevent problems like a quickly fading capacity. Toyota's cathodes, with their "truffle-like architecture," can operate at a rate of 2C over 500 cycles with nearly 100 percent coulombic efficiency. Read more at Green Car Congress.
