Silicon-Zinc Batteries for Portable Devices

Intel is going to introduce Silicon-Zinc batteries for portable devices these Silicon-Zinc batteries offer more power and better performance than Li-ion batteries currently in use. Above this these batteries are mainly focused on safety for consumers and are environment friendly.

Intel is going to introduce Silicon-Zinc batteries for portable devices. These Silicon-Zinc batteries offer more power and better performance than Li-ion batteries currently in use. Above this these batteries are mainly focused on safety for consumers and are environment friendly.

 

In case of performance Silver-Zinc batteries can provide 40 percent (Watt-hours/liter) more run time than Li-ion batteries of the same size. Moreover, Silver-Zinc batteries do not have problem of thermal runaway and fire as they are water-based chemistry which is not flammable.

 

Silver-Zinc batteries provides 1.5V per cell and can be used in place of 3.6V Li-ion batteries with minor changes in firmwire and specs in power supply in order to handle lower voltage of Silver-Zinc batteries.

 

If we talk about energy: Li-ion battery of the same size of Silver-Zinc battery offers 1.8A-h at 3.6V, whereas Silver-Zinc batteries provide 5.8A-h at 1.5 volts. This shows that energy density in case of Silver-Zinc batteries is 8.7 Watt-hours as compared to 6.48 Watt-hours of Li-ion batteries.

 

Ni-Cd and Ni-MH batteries which are also alkaline based and have similar electrolytes and voltage per cell as that of Silver-Zinc batteries have about three times less amount of energy in a comparable weight or volume of Silver-Zinc. They have good power density (Watts per Kg or Watts per liter) but lesser energy density (Watt-hours per Kg or Watt-hours per liter).
