OverviewDesignHistoryFormatsUsesPerformanceLifespanSafety
Generally, the negative electrode of a conventional lithium-ion cell is graphite made from carbon. The positive electrode is typically a metal oxide or phosphate. The electrolyte is a lithium salt in an organic solvent. The negative electrode (which is the anode when the cell is discharging) and the positive electrode (which is the cathode when discharging) are prevented from shorting by a separator. The el…

BU-402: What Is C-rate?
Losses at fast discharges reduce the discharge time and these losses also affect charge times. A C-rate of 1C is also known as a one-hour discharge; 0.5C or C/2 is a two-hour discharge and 0.2C or C/5 is a 5-hour discharge. Some high-performance batteries can be charged and discharged above 1C with moderate stress.
A Comprehensive Guide to High Rate Discharge LiPo Batteries
The C rating indicates the ratio of the charge and discharge currents of the battery. But we usually talk about the high rate means the discharge rate. For example, a 0.5C 3000 mAh battery means that the battery can support 1500 mA discharge current. On the contrary, when the battery 2C discharge rate is 600mA, the capacity is counted …

What is the maximum current which can pass in a Li_ion battery?
As a rule of thumb small li-ion or li-poly batteries can be charged and discharged at around 1C. "C" is a unit of measure for current equal to the cell capacity divided by one hour; so for a 200mAh battery, 1C is 200mA. Example: common 402025 150mAh battery from Adafruit: quick charge 1C, maximum continuous discharge 1C. ...
All You Need to Know About Li-ion Batteries
Like all batteries the Li-ion battery also has a voltage and capacity rating. The nominal voltage rating for all lithium cells will be 3.6V, so you need higher voltage specification you have to combine two or more cells in series to attain it. By default all the lithium ion cells will have a nominal voltage of only ~3.6V.

How to Calculate Battery Discharge Rate | Sciencing
Calculating Discharge Rate. You can use Peukert''s law to determine the discharge rate of a battery. Peukert''s Law is. t=Hbigg (frac {C} {IH}bigg)^k t = H (I H C)k. in which H is the rated discharge time in hours, C is the rated capacity of the discharge rate in amp-hours (also called the AH amp-hour rating), I is the discharge current in ...
How to read battery discharge curves
Terminal Voltage (Vt) is the voltage between the battery terminals when a load is applied; this is typically lower than Voc. Cut-off Voltage (Vco) is the voltage at which the battery is specified to be fully discharged. While there is usually charge remaining, operation at voltages lower than Vco can damage the battery.
