Toshiba will soon start production of 2 new interesting products which may find their way into future mobile/portable devices.
First are the new SATA SSD (Solid State Drive) drives on 1.8' and 2.5' formats. According Engadget 32, 64 and 128 GB will be available. Speed announced is read 100 MB/s while reading and 40 MB/sec writting.
With such capacity, traditional mechanical hard disk will slowly disappear from portable devices. With no moving parts, a solid state drive largely eliminates seek time, latency and other electro-mechanical delays and failures associated with a conventional hard disk drive.
The second interesting product announced by Toshiba is the so called "Super Charge ion Battery" (SCiB) which is at this stage not intended for portable devices but for industrial systems and electric vehicles.
SCiB Major Characteristics
- Safety : SCiB adopts a new negative-electrode material that offers a high level of thermal stability and a high flash point electrolyte. Its structure is resistant to internal short circuiting and thermal runaway
- Long-life cycle : Capacity loss after 3,000 cycles of rapid charge and discharge is less than 10%. SCiB batteries are able to repeat the charge-discharge cycle over 5,000 times which is equivalent to more than 10 years with a once-a-day recharge-discharge cycle.
- Rapidly rechargeable : Safety characteristics of SCiB allow recharge with a current as large as 50 amperes (A), allowing the SCiB Cell and SCiB Standard Module to recharge to 90% of full capacity in only five minutes.
- High power (practical capacity) : The SCiB has an input-output performance equivalent to that of an electric double layer capacitor.
- Temperature : Extreme temperatures supported with sufficient discharge at temperatures as low as -30°C.
SCiB batteries will first be available on the market in March 2008 with the following specifications:
- Nominal voltage : 24VDC
- Nominal capacity : 4.2 Ah
- Size : 10x30x5 cm
- Weight : 2 kg
Perhaps these batteries will also find other field of application, but for portable devices they will need to become lighter and slimmer..but batteries that get charges in five minutes are definitively very attractive for mobile users.
