licensed ultra-hard metals
Apple has acquired a worldwide exclusive license from Liquidmetal
Technologies for Consumer Electronics. The Apple Insider reported, citing one
submitted with the Securities and Exchange Commission document.
Liquid Metal developed amorphous metals. They are metal alloys which an
amorphous, have so irregular atomic structure and thus harder and more corrosion
resistant than titanium or aluminum.
In the past, Liquid Metal as an ultra-hard USB Flash Drive has been designed,
it also survives when we trample on it.
The license is a Master Transaction Agreement. Apple could extend its license
in the future so easily to other areas.

10/6/2010 - Power Lithium Battery Product Analysis
Power Lithium Battery Product Analysis
Has the "ultimate energy" and "green energy," said the lithium-ion batteries,
since the 90s of last century since the advent of electronic products from the
button batteries, cell phone, DC digital products in the lithium battery, the
electric vehicle in the battery power, is increasingly widely used in people's
production and life. Compared with other batteries, lithium-ion batteries on
whether it is from the volume, weight, or from the performance, have a great
advantage.
To use in a reasonable range of voltage within the capacity of lithium
batteries, one-sided pursuit of large capacity, high voltage is wrong. First,
any thing to go through a simple to complex, from hard to easy the process is
also flammable like gas, effectively guarantee the safety of lighters is
relatively easy, to effectively guarantee the safety of fuel tanks would much
more difficult, crash is still not fully resolved the situation when the car
caught fire and exploded. A limited volume in the more energy the more the
accumulation of bad management, is currently the largest in Suzhou Star 48V10Ah
constant can only guarantee the safety of the battery combination. Second, the
higher the voltage, the greater the capacity, protection circuit and a balanced
circuit the greater the difficulty and failure rate, so do not advocate Suzhou
Star constant and does not support beyond 48V10Ah battery combination.
Depends on the safety of lithium battery testing and
certification
A, UL certified
Today, most countries and regions in the world involving security, health,
environmental protection projects such as product requirements must be obtained
before entering the market, the safety certification. UL mark has become world
famous one of the safety certification mark.
Testing standards are as follows:
1, shell
Li-ion battery shell should have sufficient strength and rigidity sufficient
to resist the pressure of the indiscriminate, without causing fire.
User-replaceable lithium battery should have sufficient strength they would not
hurt people.
2, electrolyte
User replaceable batteries should not contain the pressure of vapor or smoke
damage the eyes of the toxic vapor and liquid, or the battery case in the normal
laboratory conditions (temperature 23 °C), by the shock fluid leakage should be
less than 5ml.
3, the use of
Li-ion battery should be used to take measures to avoid the normal charging
current, the test has an acceptable battery charge current Ic, not normal
conditions, the end product should be used in protective measures.
