However, it is generally estimated that a typical lithium-ion battery contains around 2-3 grams of lithium per cell. This amount may vary depending on the size and capacity of the battery. Manufacturing and Cost Considerations
Get a quoteHow much current a battery can supply depends on the type of battery. A lead acid battery can provide up to 2,000 amperes (A) of current while a lithium-ion battery can only provide about 700 A. The amount of current that a battery can provide also decreases as the temperature gets colder.

Get a quoteAs 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.
Get a quoteWhat Is the Recommended Standard Charging Current for Lithium Ion Batteries? The recommended standard charging current for lithium-ion batteries typically ranges from 0.5C to 1C, where "C" represents the capacity of the battery. For example, a 2000 mAh battery would ideally have a charging current between 1000 mA (0.5C) and 2000 mA (1C).

For example a 120mAh battery with a 2C max discharge current would only allow you to draw up to 240mA continuous operating current.
The higher the internal resistance, the lower the maximum current that can be supplied. For example, a lead acid battery has an internal resistance of about 0.01 ohms and can supply a maximum current of 1000 amps. A Lithium-ion battery has an internal resistance of about 0.001 ohms and can supply a maximum current of 10,000 amps.
Manufacturing a kg of Li-ion battery takes about 67 megajoule (MJ) of energy. The global warming potential of lithium-ion batteries manufacturing strongly depends on the energy source used in mining and manufacturing operations, and is difficult to estimate, but one 2019 study estimated 73 kg CO2e/kWh.
A battery can supply a current as high as its capacity rating. For example, a 1,000 mAh (1 Ah) battery can theoretically supply 1 A for one hour or 2 A for half an hour. The amount of current that a battery actually supplies depends on how quickly the device uses up the charge. What Factors Affect How Much Current a Battery Can Supply?
Characterization of a cell in a different experiment in 2017 reported round-trip efficiency of 85.5% at 2C and 97.6% at 0.1C The lifespan of a lithium-ion battery is typically defined as the number of full charge-discharge cycles to reach a failure threshold in terms of capacity loss or impedance rise.
