NEC develops prototype 4.5V, long-life manganese Li-ion battery; 30% more energy density, high capacity and light weight

Green Car Congress

The new cathode and electrolyte solution improve battery energy density by approximately 30%, increase battery capacity and decrease battery weight, all while maintaining a high level of safety, based on the results of safety tests using a multilayer laminate-type cell. from the 3.8V of existing technologies.

Alcoa and Phinergy enter joint development agreement for high energy-density aluminum-air batteries

Green Car Congress

Aluminium–air cells are high-energy density primary (non-rechargeable) batteries originally developed in the 1960s. Aluminum-air batteries (a type of metal-air cell) use a catalytic air cathode in combination with an electrolyte and an aluminum anode; the systems offer a theoretical specific energy of 8.1 Earlier post.).

Why the Next Microgrids Will Be Well Connected

Cars That Think

The winds had barely died down when electric-power specialists and others began calling for a radical overhaul of Puerto Rico’s electricity networks, one that would emphasize renewable energy, distributed generation, and, critically, microgrids. A microgrid is like a miniaturized, tightly controlled version of a power grid. percent to 2.8
