Sony’s fast Li-ions
September 28th, 2009 by admin, 1 Comment »
Sony has announced a new line of rechargeable lithium ion cells. These batteries use olivine-type lithium ion phosphate cathodes and give a much desired combination of long life, fast recharging and good power density.
These marvels are capable of as many as 2,000 charge-discharge cycles, and if that wasn’t impressive enough, they manage to retain more than 80 per cent of their capacity even after that!
The batteries will be capable of being charged up to 99 per cent of their full capacity in as little as 30 minutes – this is half that of their current batteries. Imagine the consequences this can have for mobile devices, where battery life and recharge time are especially important for those seeking more specific details, check out http://www.thinkdigit.com/d/31392.
For those seeking more specificity here are the details they have offered:
| Cell type | Cylindrical type 18650 |
| Size | Diameter 18mm, height 65mm |
| Capacity (0.2ItA) | 1.1Ah |
| Nominal Voltage | 3.2V |
| Energy Density | 95Wh/kg |
| Power Density | 1800W/kg |
| Max. continuous discharge current | 20A |
| Weight | 40g |
