Nissan and 4R Energy develop new EV charging system combining solar and Li-ion batteries

Green Car Congress

and 4R Energy Corporation, a joint venture established by Nissan and Sumitomo Corporation in September 2010 to explore second-life applications for automotive battery packs ( earlier post ), have developed a charging system for electric vehicles that combines a solar power generation system with high-capacity lithium-ion batteries.

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. MXenes based on molybdenum carbide have particularly good lithium storage capacity, but their performance soon degrades after repeated charge and discharge cycles.

PNNL study outlines requirements for grid storage, reviews four electrochemical energy storage systems: vanadium redox flow, Na-beta, Li-ion and lead-carbon

Green Car Congress

Classification of potential electrical storage for stationary applications. For example, they note, to regulate frequency, the energy storage capacity may not need to be long-lasting—minutes can be sufficient—but it must have a long cycle life because the system is likely to encounter multiple daily discharge events.

Report: VW invests in novel energy storage company QuantumScape and its solid-state “All Electron Battery”

Green Car Congress

Volkswagen executives have been hinting for awhile now about taking a different approach to high-energy-density electrical storage for long-range electric vehicles than the more “conventional” next-generation Li-ion or Li-metal battery pathways. conventional capacitors). roughly the same as the target.

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. In this €3.4-million

BMW i home energy storage system integrates 2nd-life i3 vehicle batteries

Green Car Congress

The battery storage system also includes a voltage converter and power electronics to manage the energy flow between renewable energy sources, the house interface, and the Li-Ion high-voltage battery from the BMW i3. In 2014, BMW integrated high-voltage batteries into a stationary storage system in Hamburg.

Study Finds PHEV Li-ion Cells Show Little Capacity Fade Under Combined Driving and V2G Usage; Economic Model Suggests Incentives Will Be Required for Vehicle Owners to Participate in V2G

Green Car Congress

This result implies that a LiFePO 4 /graphite–based PHEV battery pack with properly matched cells can be cycled though a very broad state of charge range without incurring any significant increase in capacity loss as a function of Ah or Wh processed.
