The batteries will be available in laptops in the US from August, use silver-zinc technology which carries more energy than lithium-ion batteries.

The report notes that this new battery should give laptops 40 per cent more run time.

Furthermore, the battery's water-based chemistry also makes it non-flammable, compared to lithium-ion, which uses dimethyl carbonate, a flammable liquid.

And the silver-zinc batteries also won't degrade in capacity during the first year, while lithium-ion batteries can lose up to 30 per cent of their capacity over that period.

Although the article also said that after a year, silver-zinc batteries start degrading at a rate similar to lithium-ion batteries.

According to a number of sources, silver-zinc is not a new technology, and has mainly been used in military and aerospace devices.
