According to the relevant provisions of the "Lithium Battery Air Transport Code" issued by the Civil Aviation Administration:

1. When the battery in the spare battery or equipment is transported as baggage, the lithium content of the lithium metal or lithium alloy battery does not exceed 2g;

2. The rated energy of the lithium ion battery should not exceed 100Wh;

3. For large-scale lithium-ion batteries with rated energy greater than 100Wh and less than 160Wh, they can be carried with them after approval by the air operator, but the number of carriers must not exceed two.

4. The equipment containing lithium battery can be placed in checked baggage or hand luggage, and the spare lithium battery can only be placed in hand luggage.

In the past ten years, with the rapid development of communication technology, mobile phone color screen technology, MMS technology, Bluetooth technology and camera technology have appeared successively, which puts higher requirements on the capacity, volume, weight and electrochemical performance of the battery. Traditional liquid lithium batteries have become increasingly unable to adapt to new demands. The emergence of a new polymer lithium-ion battery (Li-Polymer) caters to this demand.

Researchers are laying the foundation for more widespread use of lithium metal batteries. They have developed a method to mitigate the formation of dendrites -- crystal-like masses -- that damage the batteries' performance.

An electrical engineer at The University of Toledo, who nearly died as a girl in Africa because of a hospital's lack of power, has developed a new energy storage solution to make battery packs in electric vehicles, satellites, planes and grid stations last longer and cost less.

Researchers in China have developed a battery with organic compound electrodes that can function at -70 degrees Celsius -- far colder than the temperature at which lithium-ion batteries lose most of their ability to conduct and store energy. The findings could aid engineers in developing technology suited to withstand the coldest reaches of outer space or the most frigid regions on Earth.

Researchers from RMIT University in Melbourne, Australia have demonstrated for the first time a working rechargeable "proton battery" that could re-wire how we power our homes, vehicles and devices.

Did you ever think about why your phone works at all? Probably not. But, if you think about it, all portable gadgets rely on a battery to keep ticking – and some have better battery life than others. That’s why we’re going to take a peek at what keeps your phone ticking and why some batteries do better than others.

Discharge and charge rate for lithium battery is the multiple between the current and the capacity, its unit is C. for example, if the lithium ion battery has a capacity of 800mAh, and its discharging current is 1600mA, then its discharge rate is 2 C rate, if its charging current is 800Ma, then its charging rate is 1 C, normal lithium ion battery and Li polymer battery can work with 1C charging and 2C discharging.

PCB or PCM is protection circuit board, usually for small battery, typical use is for digital batteries, like mobile phone battery,camera battery,mp3 player battery,GPS batteries,heated clothing batteries and so on. Most time, Its for 3.7V or 7.4V battery, It has four basic functions of over charging, over discharging, short circuit,over current.some batteries may also need PTC and NTC.

When it is cold in winter, cars tend to have starting problems. This is not much better with electric cars, which inevitably lose capacity of their rechargeable lithium-ion batteries at freezing temperatures. Now, Chinese scientists have offered a strategy to avoid plunging battery kinetics. In a study published in the journal Angewandte Chemie, they designed a battery system with a cold-enduring hard-carbon anode and a powerful lithium-rich cathode, with the important initial lithiation step integrated.
