The button battery Button (button cell) is also called the button cell batteries, is refers to the overall dimensions as a small button battery, generally larger diameter and thickness of thin (relative to the columnar cells such as market 5 AA batteries)Button batteries from shape up to the battery, battery of the same corresponding classification with columnar cells, square battery, special-shaped battery.

Lithium ion battery manufacturing is a process that closely contact up by every process As a whole, the lithium battery manufacturing process includes pole piece producing, battery assembly process and the final injection fluid, pre-charge, formation and aging process.

General lithium battery working voltage is 37 V, and termination voltage is 3.

When the negative electrode capacity is insufficient, or there is no capacity, some or all of the lithium produced during the charging of lithium cannot be inserted between the anode graphite layer structure, and then it will analyze on the surface of the cathode It will form "dendritic crystal".

Lithium ion battery charging process can be divided into three stages: a trickle charge (low voltage pre-charge), constant current charging and constant voltage chargingThe lithium battery is pressure limiting constant current charging way, are all controlled by the IC chip, typical charging way is: detection for charging battery voltage, if the electricityDown to 3 v, have to be pre charge first, 1/10 of the charging current to set current, voltage to 3 v, in the process of charging standard.

With the continuous development of new energy technology, lithium ion battery currently widely used in all kinds of products, including buses, new energy vehicles, electric bicycles, home laptop, mobile phones, digital camera, tablet, etc, which are inseparable from the lithium ion battery.

In recent years, mobile phone and laptop battery burning explosion can't attract eyeball The electric car deflagration and lithium electricity fire is the recent news of the factory.

BYD battery technology is advanced Its lithium iron phosphate battery and Tesla ternary battery have advantages and disadvantages.

Introduction: Tesla hundred kilometers acceleration and 17 inch by 39 seconds kill all physical buttons control screen to make silicon valley spirit into North America.

Cycle life of electric cars depends on the motor Drive motor is different.
