Battery polarity refers to the direction of the electrical charge flow within a battery. A battery typically has two terminals: a positive (+) terminal and a negative (-) terminal. The positive terminal is connected to the battery''s cathode, the electrode where electrons flow out of the power supply during discharge.
The term lithium battery (LIB) refers to an entire family of battery types, with varying chemical compositions, where cathode and anode materials serve as hosts for lithium ions, and the battery contains an organic

I was using an HP 6626A power supply over the weekend to charge a lithium ion 3.7V battery. I made the stupid mistake of connecting the battery backwards (i.e., reverse polarity) to one of the 50W outputs which at the time was programmed to supply 4.2 V at 0.5 A. The length of the mistake was somewhere on the order of five seconds and the battery at the time was
What is Polarity & Reverse Polarity in a Battery? Battery Polarity. Polarity means having opposite physical properties at different points. In case of battery, the one pole or plate having more electrons is known as anode or negative (-) terminal. The other having less number of electrons is known as cathode or positive (+) terminal.

Lead-Acid Batteries: While less common, lead-acid batteries can also experience polarity reversal, often due to over-discharge or cell imbalance. Lithium-Ion Batteries: Modern lithium-ion batteries are designed with protective circuits to prevent over-discharge and polarity reversal.
Abstr. MA2016-02 897 DOI 10.1149/MA2016-02/6/897 Cell reversal in lithium ion (Li-ion) batteries is the condition of the anode electrochemical potential rising above that of the cathode, resulting in a negative voltage measured at the cell level.
While it's more common in older rechargeable batteries like NiCd, polarity reversal can potentially occur in various types of batteries, including lead-acid and, very rarely, in lithium-ion batteries, often due to extreme conditions or damage. How can I tell if my battery has reversed polarity?
This is because the other cells continue to discharge through it, effectively reversing its polarity. Rechargeable Batteries: Instances in NiCd batteries where prolonged over-discharge led to a reversal of polarity in individual cells, rendering the battery pack unstable or unusable.
Lithium-Ion Batteries: Modern lithium-ion batteries are designed with protective circuits to prevent over-discharge and polarity reversal. However, extreme conditions or damage can still lead to polarity issues.
Inconsistent Charging Practices: Frequently charging batteries for short periods or overcharging them can cause imbalance among the cells, which may result in polarity reversal in weaker cells. Using Incorrect Chargers: Chargers not suited for the battery type can contribute to uneven charging and increased risk of polarity reversal.
