What is the lithium ion battery, the advantages and disadvantages of lithium ion battery
traditional lead-acid battery is made by metal processing, and social reproduction and use link cuhk probability is will cause pollution of the environment, it is not in accordance with our modern development concept. With the development of this year to have a lithium ion battery gradually replace the position of lead-acid batteries, lithium ion batteries in the production and use of the link is not contain heavy metal elements, the environmental pollution is small. The lithium ion battery of this model was born, how about you today we take a look at what is a lithium ion battery, the advantages and disadvantages of lithium ion batteries.
what is the lithium ion battery
lithium ion battery has a relatively light in weight, large storage capacity, no memory effect, etc, and widely used & ndash; — Now many of the electronic devices are chose lithium-ion battery as the host power supply, even if the prices relatively more expensive. High energy density lithium ion battery, its storage capacity is 1 with weight of nimh batteries. 5 ~ 2 times, and have very low self-discharge rate. In addition, the lithium ion battery has virtually no & other; Memory effect & throughout; And do not contain toxic substances such as strength and its essential reason is widely used.
when to charge rechargeable batteries, rechargeable batteries, lithium ions into the anode, into lithium ions through the electrolyte to the negative movement. As a cathode carbon layer structure, it has many pores, arrived in the cathode of lithium ion is embedded into the microporous carbon layer, the embedded lithium ion, the more the higher the charge storage. Similarly, when the rechargeable battery discharge ( We use rechargeable batteries link) , embedded in the cathode carbon layer of emergence, lithium ions and movement back to the anode. Back to the anode of lithium ion, the more the higher the discharge storage. General lithium battery pack charging current is set at zero. Between 2 c and 1 c, the greater the current, the faster the charging, meanwhile rechargeable battery heating. And big electric current charge, storage capacity is not full, because the internal structure of rechargeable battery electrochemistry reaction takes time. As to pour wine, pour too soon will produce bubbles, but it is not. For rechargeable batteries, normal use is to discharge the link.
lithium battery pack discharge points to note:
the first, the discharge current to control a good
can't discharge current is too large, too large current led rechargeable battery internal structure fever, may cause permanent damage. On the phone, this is no problem, can not consider.
second, don't over discharge
absolutely can't discharge. is the most afraid of discharge, if once the discharge voltage of less than 2. 7 v, could lead to rechargeable batteries. In the mobile phone battery internal structure has been installed protection circuit, voltage is not low to the extent of the damage of rechargeable batteries, protective circuit can work, stop discharge. Rechargeable batteries discharge current, the greater the discharge the smaller storage capacity, voltage drop quickly.
lithium-ion batteries, advantages and disadvantages of
lithium ion batteries
lithium ion battery, Li- 离子,LithiumIonBattery) : lithium ion battery has a relatively light in weight, large storage capacity, no memory effect, etc, and widely used & ndash; — Now many of the electronic devices are chose lithium-ion battery as the host power supply, even if the prices relatively more expensive. High energy density lithium ion battery, its storage capacity is 1 with weight of nimh batteries. 5 ~ 2 times, and have very low self-discharge rate. In addition, the lithium ion battery has virtually no & other; Memory effect & throughout; And do not contain toxic substances such as strength and its essential reason is widely used.
1。 Long cycle life, lithium ion battery charge and discharge in 1 c rate, the cycle life is higher than or equal to five hundred times, five hundred times of electric capacity, more than seven hundred percent of nominal TongLiang. The lead-acid battery even by 0. 5 discharge to 0. 15 c to charge, the cycle life shall be less than or equal to 350 times, capacitance should be less than or equal to 60%. Low temperature discharge performance is good: lithium ion battery can be in - 25 degrees to work properly, the capacitance can be standard according to seven hundred percent of capacity, while lead-acid batteries in - 50% of the electric capacity of 10 degrees, in - 25 degrees: not to work.
2。 Charged to maintain strong ability: lithium battery pack pack will be full of electricity, two months after implantation, the capacitance is higher than or equal to eight hundred percent, while lead-acid batteries placed two months, is only 40% of the nominal capacity 50%. Line continuation ability strong, due to the weight of the lithium battery pack pack for lead-acid battery only 30%, so in the same voltage, capacitance, the lithium ion battery line continuation of ability.
3。 High specific energy: due to the volume of a lithium ion battery was only 30% of the lead-acid battery, so when using the same space of lithium ion battery energy storage is bigger than lead-acid batteries.
need to pay attention to other things external lithium-ion batteries, generally marked with English, so the user is in when to buy rechargeable batteries must see a sign of rechargeable battery piece of appearance, prevent because there is no clear and nickel cadmium rechargeable battery types, nickel-metal hydride rechargeable batteries for lithium battery. No memory effect is greatly convenient for mobile users, each time the user does not need to charge all discharge first, then charge, and also can follow one's inclinations for charging the mobile phone at any time.
