Renewable energy puts power grids to the test

To transition away from fossil fuels and towards renewables—which are intermittent by nature—we'll need to rework our entire system of power storage, transmission and distribution. Yet experts haven't yet found the right ...

Sodium-ion batteries are set to spark a renewable energy revolution

The extent to which renewables should dominate Australia's energy grids is a major issue in science and politics. Solar and wind are clearly now the cheapest form of electricity. But limits to these technologies can undermine ...

Battery (electricity)

In electronics, a battery or voltaic cell is a combination of many electrochemical Galvanic cells of identical type to store chemical energy and to deliver higher voltage or higher current than with single cells.

The battery cells create a voltage difference between the terminals of each cell and hence to its combination in battery. When an external electrical circuit is connected to the battery, then the battery drives electrons through the circuit and electrical work is done. Since the invention of the first Voltaic pile in 1800 by Alessandro Volta, the battery has become a common power source for many household and industrial applications, and is now a multi-billion dollar industry.
