Lithium Battery Life Could Double by Adding Graphene Girders to Silicon Electrodes

Graphite has been the default choice of active material for anodes in lithium-ion batteries since their original launch by Sony but researchers and manufacturers have long sought a way to replace graphite with silicon, as it is an abundantly available element with ten times

Tesla and Australia will turn 50,000 homes into a virtual solar power plant

Mark Austin for DigitalTrends: Installation of the 5kW solar panels and Tesla batteries has already begun on 1,100 public housing properties, with 24,000 more to follow. After that, the program will be opened up to as many as 50,000 South Australian homes.

A new approach to rechargeable batteries

David L. Chandler, MIT News Office: New metal-mesh membrane could solve longstanding problems and lead to inexpensive power storage.

The Future of Residential Home Energy Storage

2017 - Most Popular Article - With the market growing so rapidly, consumers need to understand which product best suits their household's energy needs. Again, the key is starting with a customer's energy usage and determining how they will use an energy storage system.

Powerwall Type Batteries

There are many reasons to purchase a battery system for the home or business, starting with natural disasters, but a battery system, tied into a solar system, will maximize self-consumption of solar power, reduce grid costs, increase the resiliency of electricity, and take a home or business completely off grid with minimal fossil fuels.

Understanding Battery Degradation

Batteries may degrade gracefully up to a point, then experience "rapid fade" and lose capacity quickly. A system that has been designed to meet a given level of demand will, at some point, be unable to do so.

MIT turns to millennia-old tech for renewable energy storage

Barbara Eldredge for Curbed: Indeed, MIT researchers have reinvented firebricks, a Bronze-Age technology created by the Hittites-who occupied what is today Turkey, in the 17th century BC. Firebricks were designed by the Hittites to retain heat for long periods of time, if properly insulated.

Tech Guru Unveils New Battery To Challenge Lithium-Ion

The three main possible applications of the new alkaline battery technology would be consumer electronics, electric cars, and energy storage for the power grid, according to the developers.

Study Suggests Route to Improving Rechargeable Lithium Batteries

Smooth surfaces may prevent harmful deposits from working their way into a solid electrolyte.

Case Study: Energy storage enables SEV to optimize wind power for the Faroe Islands

The latest step in SEV's renewable energy program is a new 12 MW wind farm located in Húsahagi, on the island of Streymoy. Since coming on line in 2014, the wind farm has increased the islands' wind share to 26 percent of total electricity production.

Panasonic Joins Push to Put Photovoltaics on More Car Roofs

By Chisaki Watanabe, Emi Nobuhiro, and Kevin Buckland for Bloomberg: The tech giant thinks solar roof panels are the future for hybrids and EVs.

Powervault to give electric car batteries a second life in smart homes

Jessica Twentyman for Internet of Business: Automaker Renault is partnering with UK-based smart home energy storage specialist Powervault in a deal that will see batteries previously used to power electric vehicles (EVs) redeployed to store solar power in homes.

Intersolar Q&A with Jeff Myles of Rolls Battery

Rolls is excited to announce the expansion of our 5000 Series range with the launch of select premium models with enhanced charge performance and added capacity. With improved charge efficiency at lower voltages, these models require shorter recharge times which is especially beneficial in off-grid renewable energy applications.

GTM: 10 US states have energy storage pipelines greater than 100MW

Danielle Ola for Energy Storage News: According to the latest GTM Research figures, energy storage is coming into its own and is no longer confined to a handful of US states. 21 states now have 20MW of storage projects proposed, in construction or deployed. Further, 10 states have pipelines of more than 100MW.

Stabilizing battery storage

Morgan Sherburne for U of Michigan News:  An issue that has long plagued renewable energy facilities is how to efficiently store energy collected from sun or wind. Now, University of Michigan and University of Utah chemists have developed an energy-storing molecule that is 1,000 times more stable than current compounds, potentially leading to a longer-lived, more efficient battery. The researchers are working to develop industrial-scale batteries that can store large amounts of energy for deployment when the sun sets or the wind stops blowing. Deep-cycle lead batteries or lithium ion batteries are already on the market, but each type presents challenges, including the significant environmental hazards of disposal. Also, these kinds of batteries wear out relatively quickly.   Cont'd...
