New Silver-zinc Battery provides longer Battery Life for Laptops & Mobiles

Battery

Silver-zinc batteries pack more energy than lithium-ion batteries, giving laptops 40 percent more run time, according to Dueber. If a laptop runs for two hours with a lithium-ion battery, it should run for closer to three hours with a silver-zinc battery.

The batteries will be available in consumer and business laptops from major PC makers starting in August, according to Ross Dueber, the CEO of ZPower, although he declined to name any of the vendors on Thursday.

The battery’s water-based chemistry also makes it nonflammable, compared to lithium-ion, which uses dimethyl carbonate, a flammable liquid. Cells can go off “like firecrackers” in lithium-ion batteries.

It also remains to be seen if silver-zinc batteries can compete on price, since lithium-ion is relatively cheap. The silver-zinc batteries contain silver, which can be expensive.

Green Cell battery unveiled

 Green Cell

If every portable device used the same batteries, and every battery could be recharged – surely the amount of electronic waste dumped each year would drastically drop.

This is the notion behind the Green Cell concept.

use safe, standardized rechargeable batteries in all portable gadgets. The environment would benefit from fewer batteries being thrown away, and you’d need fewer chargers for all your gear. Green Cell batteries would even be made without toxic chemicals, and sold from vending machines that double as recycling points.

It’s a staggeringly sensible idea, which might be why it earned third place in the Greener Gadgets competition.

The main drawback: persuading manufacturers to configure every gizmo to the size and voltage of standard rechargeable cells. Standardization worked pretty well with the AA battery and USB, though, But will they be able to persuade manufacturers to configure every gizmo to the size and voltage of standard rechargeable cells – I hope so.
