Knowledge about li-ion batteries

1. Lithium ion battery high performance

Does not contain any mercury, the cadmium virulent element, is thetrue environmental protection battery.
Besides has flowed the hot dual protection, but also in sets at theintelligent IC protection circuit.
Has the power carrying capacity, fully satisfies the camera/numericalcode camera each correlation load power request, displays theoutstanding constant pressure source characteristic.
But fast completes the charging-up, completely does not have thememory effect.
Even if the high efficiency sufficiently puts, high frequency use, itscycle life still compared to nickel hydrogen battery more than 1 timesabove.
The electrically charged maintenance ability is strong, the monthelectrically charged maintenance rate is bigger than 92%.
Has the finest internal uniformity, guaranteed each time "sufficientlyputs" the process uniformity, guarantees the battery longest overalllife

2. Lithium ion battery principle of work

The lithium ion battery principle of work refers to its sufficientelectric discharge principle. When carries on the charge to thebattery, on the battery positive electrode has the lithium ionproduction, the production lithium ion after the electrolyte movementto the cathode. But assumes the laminated structure as the cathodecarbon, it has very many pores, arrives the cathode the lithium ion toinsert to in the carbon level pore, inserts lithium ion more, thecharging capacity is higher. When carries on the electric discharge tothe battery, inlays the lithium ion leaves in the cathode carbonlevel, also the movement returns to the positive electrode. Returns tothe positive electrode the lithium ion many, the discharge capacity ishigher. Usually said the battery capacity refers is the dischargecapacity. The lithium ion battery sufficient electric dischargeprocess is from the positive electrode -> cathode -> positiveelectrode rate process.

3. Lithium ion battery security feature

Regarding the lithium ion battery security performance inspectiontarget, on international had stipulated below the extremely strictstandard, a qualified lithium ion battery should satisfy the conditionin the security performance:

<1> Short-circuits: Does not catch fire, does not explode

<2> Hot box experiment: Does not catch fire, does not explode (150 ℃constant temperatures 10min)

<3> The needle perverses: Does not explode (penetrates battery with Ф the3mm nail)

<4> Plate impact: Does not cook meals, does not explode (the 10kg heavyitem to pound from the 1M high place to battery)

<5> Burns down: Does not explode (coal gas flame to bake battery)
