What does it mean when a battery still has high voltage but

The internal resistance of the battery is high? That would explain why the voltage is high when there is no current but why there is no voltage when there is current. The more current is drawn by the battery, the more voltage is dropped across the internal resistance and therefore the less voltage actually appears on the battery terminals.

BU-303: Confusion with Voltages

The nominal voltage of lithium-ion is 3.60V/cell. Some cell manufacturers mark their Li-ion as 3.70V/cell or higher. This offers a marketing advantage because the higher voltage boosts the watt-hours on paper (voltage multiplied by current equals watts). The 3.70V/cell rating also creates unfamiliar references of 11.1V and 14.8V when connecting

Lithium-Ion Battery

The lithium ions are small enough to be able to move through a micro-permeable separator between the anode and cathode. In part because of lithium''s small atomic weight and radius (third only to hydrogen and helium), Li-ion batteries are capable of having a very high voltage and charge storage per unit mass and unit volume.

6 FAQs about [Lithium battery voltage is very high but no current]

Why do lithium ion batteries need a high charging voltage?

Additionally, high charging voltages can hasten the breakdown of solid electrolyte interface (SEI) , which reduces the reversible capacity and service life, and, in extreme situations, causes safety issues with lithium-ion batteries.

How many volts can a lithium ion battery charge?

Currently, most lithium-ion batteries have operating potential ranges of 2.0–4.3 V . To obtain lithium-ion batteries with higher energy densities, the charging cutoff voltages can usually be increased.

What happens if battery voltage is too high?

Be wary though: if the battery voltage recovers on its own to higher than the set voltage, the PSU will be forced to sink current, which most don't support. I don't think you'll damage the PSU in this scenario, but you're in an area outside of the operating conditions of the PSU, so it's essentially undefined how it'll behave.

How do electrolyte properties affect a lithium-ion battery?

The electrolyte directly contacts the essential parts of a lithium-ion battery, and as a result, the electrochemical properties of the electrolyte have a significant impact on the voltage platform, charge discharge capacity, energy density, service life, and rate discharge performance.

What determines the maximum current a battery can supply?

It only determines how long the battery can supply a current for (that is, how much energy is can output over a period of time). The max current is determined by it's internal resistance. Many 4.2V lipo batteries can supply much more current than 9V batteries since they tend have lower internal resistances.

How does a lithium ion battery work?

The total performance of a battery is directly impacted by the electrochemical performance of the electrolyte, which is served as a channel for the transfer of lithium-ions. Lithium-ion battery research has always been designed to increase the energy densities of these batteries.
