Too high a voltage tends to cause a catastrophic breakdown of a transistor. Once you apply over-voltage stress and the transistor breaks down, the pin will show short circuit (usually to ground). If you catch it, or limit the fault current some how, this type of failure will not be visible outside of the IC.
Some circuits are designed to self-protect and adjust to keep currents within safe values. Any change that increased current could result in damage due to excessive heat from the increased current. The matter of exceeding voltage ratings is also related to current, but in a different way.
Connecting a higher-current power supply to a lithium-ion charger will damage the battery. Why? I am not asking how the battery gets damaged, because that answer is straightfoward. What I am asking is why lithium-ion chargers allow batteries to be damaged by excessive charge current in the first place.
When the voltage across an insulator gets too high, it is possible that the insulator will stop insulating and will instead start letting some current through. This current flow can cause damage. If voltages are high enough, dielectric breakdown can result in arcing, which can cause heating, pitting, etc.
For a lithium polymer battery the charger limits both the voltage and current into the battery, with voltage limit set to something like 4.0 to 4.2V and the current limit to a 1C rate at most, for a 1 hour charge. Likely somewhat slower in order to do as little damage to the battery as possible while giving the user an acceptably fast charge time.
Excessive charge rates can end up with pure metallic lithium 'where it ought not be' with capacity effects at best and vent with flame at worst. Among other things LiIon battery lifetimes are due to the structure being mechanically flexed as Li is moved around the cell.

5 · Damage to the Battery: When you charge a battery with a voltage higher than specified, the excess voltage can result in damage to the internal components. Batteries are designed with specific voltage limits. Exceeding these limits can cause irreversible harm and may require battery replacement.
State of Charge (SOC): A fully charged battery will have a higher voltage than a battery that''s running low. When you charge a battery, the voltage gradually increases until it reaches a safe maximum level. Temperature: Temperature can also play a role in battery voltage.
When the voltage across an insulator gets too high, it is possible that the insulator will stop insulating and will instead start letting some current through. This current flow can cause damage. If voltages are high enough, dielectric breakdown can result in arcing, which can cause heating, pitting, etc.
In order to protect the battery cell, it is not recommended to charge the lithium battery with a high current. If the battery is charged with a low current and a large current, it will heat up quickly and damage the battery. If you want to prolong the life, you can charge it at 0.3C. Higher (15C) charge and discharge current, suitable for use ...

Exceeding the maximum voltage for a battery can cause damage. For most lithium-ion batteries, this threshold is typically around 4.2V per cell. Charging beyond this voltage can lead to overheating, reduced lifespan, and even thermal runaway. For lead-acid batteries, the maximum voltage is usually around 2.45V per cell. Understanding Voltage ...

As with most things in engineering, arbitrarily increasing the pack voltage isn''t unequivocally a good thing, and that''s even without invoking a reductio ad absurdum argument (e.g. if 1 kV is better than 100 V, then 10 kV is better than 1 kV, etc.). Still, there are some benefits to increasing the pack voltage, and the most obvious is that less cross-sectional area in …
Drawing excessive current from lithium batteries can lead to overheating and thermal runaway, risking fire or explosion. It may also cause permanent damage to the battery cells, reducing efficiency and lifespan. Always adhere to …

Yes, high current can damage a battery. Excessive charging voltage can lead to overcharging, causing heat buildup and potential cell damage. This may result in reduced capacity, shortened cycle life, or even catastrophic failure if safety mechanisms fail.
Although a high current battery is ideal for a fast and efficient power supply, too much current supply may cause damage to the circuit. When using a high current battery with a circuit rated for a lower current draw and lower capacity, this may result in damage to one or more components of the circuit which may include;
A volt is a potential difference across a conductor when a current of one ampere (Amp) dissipates one watt of power. Voltage is then defined as the pressure that pushes electrons (current) between two points to enable them to power something. Battery voltage refers to the difference in charge due to the difference in the number of electrons between the negative and …

Definition of High Voltage. In the realm of electricity, "high voltage" is a relative term, its value largely depends on the context. The International Electrotechnical Commission (IEC) defines high voltage as any voltage over 1000 volts for alternating current (AC) and over 1500 volts for direct current (DC).
