Why don''t battery manufacturers make 5 V batteries?
$begingroup$ @asdfex - actually it''s not necessarily trivial to generate 3.3v over the full range of a single lithium cell, because pulse-load brownout towards the end of discharge can run into regulator dropout overhead. However many "3.3v" parts will run quite happily and in-spec with a 3v or even 2.7v regulator, which can provide more margin. And one
ELI5: Why Do Electric Cars Still Use 12-Volt Batteries?
When an electric car is turned off, the high voltage battery is physically disconnected to prevent it from draining, and as a safety precaution so you don''t get shocked looking under the hood. The 12v accessories which need to keep running while the car is off (such as the door locks) wouldn''t work unless there is a backup 12v power source.

Eli5: Why do lithium ion batteries explode if smashed, even
As a result, expansion must be accounted for when designing any sort of container for a battery. If you don''t allow for any expansion, the expansion will crush the innards and cause a short. If you don''t have a container strong enough, the cell can over-expand and puff up like a pillow. This generally is a big consideration when using pouch cells.
ELI5: why haven''t the large and heavy lead batteries in cars been
Lead-acid batteries provide a better voltage than than lithium and nickel batteries. They don''t do that either. Lithium ion and nickel metal hydride provide higher and lower voltage per cell, but you just stack as many cells in series as you need for your desired voltage, whatever the battery type.
lithium ion
The chip you mention is for controlling the DC/DC converter that does the charging. It would be unwise to only use that chip for a Li-Ion system. You would have to combine that with the BQ769X series (7692 for 3-5, 7693 for 6-10, and 7694 for 11-15 cells). They may have chips for 1-2 cells, but I am not sure.

What are the gases in bloated Lithium-Ion batteries?
It''s a common misconception that there is lithium metal present in lithium ion batteries. They only contain a small amount of lithium intercalated into graphite at the anode and metal oxide cathodes. Water ingress is indicative of a major flaw in the battery pouch itself which also provide a route for the pressure built up to be released.
Why are lithium-ion batteries, and not some other kind of battery
Charging and recharging a battery wears it out, but lithium-ion batteries are also long-lasting. Today''s EV batteries can be recharged at least 1,000 times and sometimes many more without losing their capacity, says Chiang. Plus, unused lithium-ion batteries lose their charge at a much slower rate than other types of batteries.

eli5: Why do regular batteries last for so long whereas
NiCad batteries haver a terrible "memory effect" to them that newer battery chemistries don''t have (at least to the same extent). From 20 years ago memory when I was making the change from NiCad to NiMH to power the electronics in my remote control turbine powered jet, what I remember is the NiCads if you didn''t keep them charged to full the battery would deplete
Eli5: Why are all batteries not rechargeable and what causes batteries
It has to do with the construction/design of the battery, non rechargeable ones are simpler to create, but they don''t have the pathway to reverse the reaction and recharge the batteries. Simply put, batteries are a chemical reaction that uses the flow of ions to create an electric current.
ELI5. Why do most devices requiring AA or AAA batteries need
The various chemical mixes used to create AA batteries produce 1.5v per cell, meaning such batteries can only produce multiples of 1.5v - that is, 1.5v, 3v, 4.5v, and so on. A 9v battery generally has the same chemical mixture, but with 6 cells in series internally, thus producing 9v. Other battery cell technologies produce: 1.2v (NiCd)
