Lithium polymer battery use and Assembly considerations

Lithium polymer battery is a electrolytic quality for gel rubber-like, and packaging soft of lithium battery, in civilian market often was called soft package lithium battery, this makes lithium battery electric core has and General liquid lithium ion battery not as of place, thus some special of note matters, following on electric core in using and assembled process in the may appeared of not right practices proposed following note matters.
First, in the use of batteries, including on aluminum-plastic composite films, top edge (end edge), lateral edge, its protection and measures to avoid mechanical impact, short circuit.
1 Aluminum-plastic laminated film packaging protection: mainly to avoid being stabbed sharp parts are damaged. To this end, should often clean batteries around the environment, contact against sharp parts or bump the batteries, take time to wear gloves, avoid fingernails scratching the surface.
2 The top edge and side edge protection: to avoid damage to edges and side edges, damage the sealing effect, bending the top edge should be forbidden and side edge and core design reliable insulation isolation measures must be taken to avoid negative and the butt welding of aluminum-plastic composite film short circuit.
3 Handles protection: lithium polymer battery positive terminal aluminum handle, cathode Terminal nickel handles. Due to the very thin handle, bent should be prohibited and should be avoided during the production process handles contact with the aluminum-plastic composite film, with strict isolation rings film.
4 Avoid mechanical impact, such as falls, curb and bending batteries and accidentally trample on batteries.
5 Or the use of metal, wires and short circuits the connection polarity.
One battery ready, the next step is combined with the shell and battery protection circuit module correctly, making it a polymer battery, considerations for this process are:
1 Shell design: a. with sufficient mechanical strength to prevent the batteries from external mechanical damage b. When installing the enclosures, batteries, avoid the sharp edges of the shell scratch batteries and c. Prevention of aluminum-plastic composite membrane laminated aluminum in contact with external short circuit.
2 Batteries must be designed to protect circuits: including scientific set of minimum voltage, over current protection, turbine core using a combination of battery unit (single core) to overcharge protection.
3 Aluminum handle, positive transfer through nickel, as well as batteries and circuit board connections should use ultrasonic welding or spot welding technology.
4 Positioning, reliable batteries, batteries assembled fastened within the shell, and not activities, so that the whole structure of lithium ion battery in a State of consolidation.

Lithium batteries and lithium-ion batteries are popular fast cell variety, in literature and in real life, it was discovered that lithium batteries and lithium-ion batteries in use sometimes similar, sometimes interchangeably, the reason is that lithium battery and lithium-ion batteries is different and has inherited and developed concepts of the relationship, it is no wonder that people will confuse the two. So-called lithium battery, is to metal lithium do negative activity material of battery General, and lithium ion battery is refers to two species different of can reversible of embedded and off embedded lithium ion of embedded lithium compounds respectively as battery cathode and negative of two times battery system, lithium battery and lithium ion battery of same points is in cathode and electrolytic quality, two species battery are used metal oxide and sulfide as cathode, and to organic solvent - Inorganic salts as electrolyte system.

Lithium-ion batteries, capacitors and lithium ion capacitor

Japan's Fujitsu Company set up a capacitor business promoting room, its Chief named LingMuJingSheng recently wrote a universal knowledge of lithium ion capacitor and with lithium-ion batteries and electric double-layer capacitors compared the features. Fujitsu develops lithium-ion capacitor is characterized by high output power, charge and discharge cycle characteristics of excellent, high power is needed, mainly for the hybrid car field. 1 .Self-comparison of discharge, voltage, capacity, Lithium ion capacitor with the lithium-ion battery material differences mainly in the positive. The cathode of lithium ion capacitor is activated carbon; this is different from lithium ion battery lithium oxide. 2 .Safety: lithium battery replace the nickel-metal hydroxide batteries and lead acid batteries is a great progress in battery technology, but safety of lithium-ion batteries also have occurred, as noted above, this is caused by their different cathode structure. Lithium batte...

The lithium-ion batteries

First discussed the situation of lithium ion battery , unique opportunities and challenges. The EU unveiled the two chemicals-related laws, coupled with rising raw material, China's export tax rebate policy adjustment, the lithium-ion battery market with new opportunities. Faced with the grim situation of energy shortage and environmental, for growing of batteries and storage batteries. At present, the lithium battery industry in our country should follow up market requirements, active measures to properly address issues such as: Manual and semi-automatic, automatic; battery with battery safety Self-contained and complete industrial chains in response to market demand and sustainable development and a series of relationships. Secondly, the author discusses at great length the development of battery-powered vehicles (BEV) is threefold: to store low electricity instead of oil, electricity, and reduce environmental pollution. Now should be to develop a petrol hybrid cars (PH...
