powerful chemical cocktail, with a drawback - small lithium ion battery
A lithium-
Ion batteries work just like most other chemical batteries.
Particles with charge (
In this case, lithium ion)
Move to one terminal when applying energy, and move to another terminal when energy runs out. Lithium-
Ion batteries are actually a series of batteries because the chemical composition of terminals and other components is different.
They have a higher energy density, which means they can store more kilowatts.
The working time per unit weight and volume is longer than other chemicals.
But they have shortcomings.
One is that when all the batteries are warm, it makes some parts of them expand, which is a chemical soup in which the ions in lithium
Experts say electrolyte ion batteries swim more than the electrolyte of other chemicals expands.
Because lithium
The ion battery is always sealed and it has to withstand the pressure of expansion.
Otherwise, it will open or disconnect internally.
Electrolyte in lithium-
Ion batteries include hydrocarbons.
So it burns, or at least a chemical reaction occurs where there is no fire, generating heat and smoke.
If the electrolyte in lead
The battery is dead, it will cause problems, but it will not burn out.
All batteries generate heat when they are charged and discharged.
The efficiency of non-rechargeable chemical batteries is 100%.
In other words, they never have as much energy as they put into them.
Energy without a round trip will eventually turn into heat. If the lithium-
The ion battery is small in size, so its surface area is large compared with its component volume, and it can dissipate heat well.
If it is large, or if it is a pack of many batteries, the cooling system must be installed or the path through which the air flows is set. When lithium-
Ion batteries were originally produced commercially and in the early 1990 s they were small for manual useheld devices.
Now, however, they are much larger when they enter cars and planes.
The Boeing 787 is 50 to 100% bigger than the lead.
Typical car battery.
The battery pack used in electric vehicles is much larger than this.
