41MW battery for UK national grid

article-energy-storage-02

The Midlands is to get a 41MW grid-connected battery, built by GE and operated by Arenko which has energy trading software. “This is a private grid scale project,” Arenko CEO Rupert Newland told Electronics Weekly. “Using Arenko’s trading platform, which can access multiple energy markets in real time, the project will be able to respond to and effectively handle system-wide ...

Comment: It’s time for a DC homecoming

Blane-Judd-Chair-of-the-IETs-Built-Environment-panel

There is a certain irony to the fact that as I sat down to write this opinion piece we had a power cut, writes Blane Judd. It was a Sunday morning so not as bad as it could have been, but still an inconvenience. While my article was protected because I was using the laptop, which just transferred to battery, ...

Li-ion thermal knowledge pooled into one place

Rice Uni Li ion cell possibilities

US researchers have collated the temperature performance of different Li-ion cell technologies with a view to improving batteries. “People have not looked that studiously at temperature constraints. We searched hard to find one paper that talks about all the problems at the same time and what all the individual components experience at extreme temperatures, and we couldn’t find one,” said ...

Zinc sponge anode makes Li-ion alternative rechargeable

The US Navy has created a rechargeable aqueous zinc battery with performance approaching Li-ion cells. While useful in non-rechargeable applications – it is the basis for ‘alkaline cells’ – zinc electrodes tend to grow dendrites (whiskers) when charged, wrecking the cell. Scientists at the US Naval Research Laboratory (NRL) have created nickel-zinc batteries with 3D sponge zinc anode instead of ...

Solid-state electrolytes and the quest for a safer battery

IDTechEx Solid-state and polymer batteries 2017 2027 Technology, markets, forecasts

2016 was the year of Li-ion batteries’ silver jubilee, a coming of age that has not been hassle-free, as Samsung’s Firegate showed us, writes Dr Lorenzo Grande, technology analyst at market research firm IDTechEx. This year might mark the first significant switch to new materials in the electrolyte compartment, with both large and small companies trying to bring inorganic and ...

Not quite how lithium ions move in batteries

Institute for Basic Science Li-ion transport 10ps

The theory explaining how lithium ions move in batteries is not quite right, according to the Institute for Basic Science (IBS) in Korea, which has been examining the process in femtosecond detail. The model was, said IBS, that lithium ions (green dots) move surrounded by a shell of ethylene carbonate (EC, blue ovals) molecules, and that these entities (‘solvation shells’ or ...

Hydronium-ion battery mooted for grid storage

hydronium-ion battery Oregon simulated PTCDA unit cell

Hydronium-ion batteries show promise for sustainable high-power energy storage, according to scientists at Oregon State University, which claims to have developed the world’s first battery to use only hydronium (H3O+) ions as the charge carrier. The hydronium ions are reversibly stored in an electrode made from the organic crystalline solid perylenetetracarboxylic dianhydridem (PTCDA). Dilute sulphuric acid is the electrolyte. “It doesn’t use lithium or ...

Tiny battery connector handles 10A for faster charging

Kyocera 7129 board-to-board connector

Kyocera has managed to squeeze 10A capability into a 2.2 x 5.64mm board to board connector with 0.7mm stack height. Part of the 7129 series, it is intended to allow high battery charging currents in portable devices such as smartphones, tablets and wearables. It also includes two signal pins. According to the firm, it has metal guides to prevent mating misalignment damage ...
