Re: battery

It has to do with the chemistry of the materials. Other voltages can be made, but they materials are either expensive or dangerous.

Re: battery

Go to Panasonic website, this in one example.
https://www.panasonic.com/industrial/battery/oem/chem/nicmet/index.html
From there you can get detailed informations regarding all aspects of rechargeable batteries.

Re: battery

It's the chemical redox potential between several material, so it's become a standard voltage....like 1.25V for bandgap voltage references

need some datum on the TI bqxxxx.
How fit the different material during the circuit design?
