Can a reverse polarity Lithium Ion Battery connection damage

I was using an HP 6626A power supply over the weekend to charge a lithium ion 3.7V battery.

The problem comes when partially or fully discharged batteries are mixed with new batteries, thus creating a situation where the discharged cell could be reverse charged by the new cell. This is a big "no no" for primary lithium cells and could result in explosion. BAT1 in this case is the discharged cell: simulate this circuit

Lithium-ion batteries explained

During charging, an external electrical power source (the charging circuit) applies an over-voltage (a higher voltage than the battery produces, of the same polarity), forcing a charging current to flow within the battery from the positive to the negative electrode, i.e. in the reverse direction of a discharge current under normal conditions. The lithium ions then migrate

Specifically, when cells are in series, the one(s) with the least current capacity (due to imbalances during manufacture, or uneven deterioration) will be reverse charged by the remaining cells as the last few coulombs are withdrawn. In this state, the battery as a whole still would have a small net charge, as opposed to reverse charge... but then, over time, all the

6 FAQs about [Lithium battery reverse current]

What happens if there is a reverse current?

However when there is a reverse current, the resistor will limit the flow back into the device to a safe level. The GND network limits the current through the ground pin of the high side switch by Equation 1

What is battery reversal protection?

A variety of circuits can provide this assurance. The simplest form of battery-reversal protection is a diode in series with the positive supply line (Figure 1a). The diode allows current from a correctly installed battery to flow to the load and blocks current flow to a backward-installed battery.

Can a shunt diode be used to reverse a battery?

(The regulator output is one diode drop below the battery voltage, so the regulator drops out prematurely.) If the application calls for an alkaline or other type of battery with relatively high output impedance, you can guard against reverse installations using a parallel (shunt) diode. The circuit in Figure 1b is simple but far from ideal.

What is a diode & a transistor for reverse battery protection?

To provide these electronic safeguards, manufacturers typically chose either a diode or transistor for reverse battery protection. The simplest protection against reverse battery protection is a diode in series with the battery, as seen in Figure 1. Figure 1. Diode in Series With Battery

How can a battery prevent reversal?

In general, these batteries offer no mechanical means for preventing the reversal of one or more cells. For these systems, a designer must ensure that any flow of reverse current is low enough to avoid damaging the circuit or the battery. A variety of circuits can provide this assurance.

What is a good battery reversal transistor?

For battery voltages lower than 10V but higher than 2.7V, you can use a low-voltage PMOS FET, such as the Siliconix Si9433DY or Si9435DY. Providing battery-reversal protection for battery voltages lower than 2.7V, on the other hand, can be a challenge. One solution is to use a bipolar transistor, which entails base-current losses.
