One is to develop a new cathode material with a higher specific capacity (e.g., increasing the nickel content in the layer transition metal oxide cathode material, as the more nickel the cathode can extract more Li + at the same voltage), and the other is to increase the upper-limit charging voltage of the battery. Obviously, the latter is ...

Batteries range in voltage from a few hundredths of a volt to many hundreds of volts, depending on both the size of the battery and the materials from which it is made. They are an excellent way to power various forms of devices, no matter what the voltage requirements of those devices.
The movement of the lithium ions causes an electrical potential difference called "voltage." When you hook your electronic devices up to the battery, electrons (not lithium-ions) flow through your device and power it. Lithium-Ion Battery Vs. Lithium-Ion Cell. Multiple lithium-ion cells connect internally to make up a lithium-ion battery.
The voltage across the terminals of a battery, for example, is less than the emf when the battery supplies current, and it declines further as the battery is depleted or loaded down. However, if the device''s output voltage can be measured without drawing current, then output voltage will equal emf (even for a very depleted battery).
A battery''s capacity is the amount of electric charge it can deliver at a voltage that does not drop below the specified terminal voltage. The more electrode material contained in the cell the greater its capacity. A small cell has less capacity than a larger cell with the same chemistry, although they develop the same open-circuit voltage. [49]
Batteries are perhaps the most prevalent and oldest forms of energy storage technology in human history. 4 Nonetheless, it was not until 1749 that the term "battery" was coined by Benjamin Franklin to describe several capacitors (known as Leyden jars, after the town in which it was discovered), connected in series. The term "battery" was …
