Solid-state battery startup Talent New Energy unveils cell
This sets new industry records for single cell capacity and highest energy density for lithium batteries, Talent said in a statement. For comparison, Nio''s (NYSE: NIO) 150-kWh semi-solid-state battery pack uses cells from Beijing WeLion New Energy Technology, with a capacity of 360 Wh/kg.
How to Measure Battery Capacity
The formula for determining the energy capacity of a lithium battery is: Energy Capacity (Wh) = Voltage (V) x Amp-Hours (Ah) For example, if a lithium battery has a voltage of 11.1V and an amp-hour rating of 3,500mAh, its energy capacity would be: Energy Capacity (Wh) = 11.1V x 3.5Ah = 38.85Wh Lead-Acid Batteries

How Batteries Are Measured
The voltage of a battery cell is determined by the chemistry used inside. For example, all Alkaline cells are 1.5V, all lead-acid''s are 2V, and lithiums are 3V. Batteries can be made of multiple cells, so for example, you''ll rarely see a 2V lead-acid battery. Usually they are connected together inside to make a 6V, 12V or 24V battery.
How to measure battery capacity with a multimeter?
Battery capacity is how much energy a battery can provide on a full charge. This means that bigger batteries with a higher capacity will last longer in the same application than smaller ones. Unfortunately, a battery''s actual capacity can be far less than advertised. This could be due to the battery''s age, damage within the cells, or false ...

Battery Capacity
Since the capacity of a battery does not have a unique value, the manufacturers write an approximate value on their products. The approximate value is called Nominal Capacity and does not mean that it is the exact capacity of the cell. Fig. 2.2 shows a typical lithium battery used for cell phones. As it is indicated on the cover of the cell, it has Q n = 3500 …
