Lithium ion
Lithium-ion batteries (Li/Ion, LIB) are rechargeable secondary batteries. Without lithium-ion batteries (Li/Ion, LIB), success in electromobility
and in electrical devices would be inconceivable.
No battery type is as versatile as lithium-ion batteries.
- It has very high energy densities (about four times higher than lead-acid batteries)
- It has a high cell voltage: up to 3.7 V nominal power. One lithium-ion cell can replace three NiCd or NiMH cells, which are only 1.2 V.
Rated voltage: 3.6V - 3.7V
Charging end voltage: 4.2V
Selbstentladung: < 2% / Monat

Lithium Polymer (LiPoly)
Lithium polymer (Li/Poly) batteries are rechargeable secondary batteries.
No battery type is as diverse in length, width and thickness as the
lithium polymer battery.
There are dozens of electrode materials with different properties in the lithium polymer battery as well.
Depending on which one is combined as anode and cathode, the result is batteries that are better or worse suited for differentiated applications.
For this very reason, it is very important to define the battery type precisely when talking about a lithium-ion battery.
Lithium polymer batteries can be built extremely flat and have a thickness of less than one millimeter. They are ideal for smart cards, smart wearables, smartphones, tablets and laptops.
- They have a 20% higher energy density compared to lithium-ion batteries.
- They have a high cell voltage: up to 3.8 V nominal power.
- Charging end voltage: 4.2V
- Selbstentladung: < 2% / Monat

There are hardly any toxic heavy metals in a lithium iron phosphate battery When it comes to recycling, the lithium iron phosphate battery scores points compared to other battery systems because almost all the metals used are recycled.
Lithium iron phosphate (LiFePo4)
Lithium iron phosphate (LFP; LiFePo4) batteries are rechargeable secondary batteries.
Lithium iron phosphate batteries consist of phosphate based materials, have better thermal and chemical stabilities, than other lithium ion cathode materials.
Lithium iron phosphate cells are considered very safe batteries. They are fire resistant in case of overcharge and more resistant in case of short circuit. In the event of misuse, this cathode material does not emit oxygen, does not burn and, accordingly, is insensitive to heat.
Lithium iron phosphate cells also have a longer life (2,000 to 5,000 cycles).
The cathodes of the LFP mostly support higher voltages and accordingly they can handle higher charge and discharge currents, which makes them suitable for use in fast-charging lithium-ion battery systems.

Nickel metal hydride
(NiMH)
Nickel metal hydride (Ni/MH) batteries are rechargeable secondary batteries.

Cadmium is a very toxic heavy metal that is hazardous to the environment and health, attacking the liver, kidneys and bones in humans and mammals.
The placing on the market of portable Ni/Cd batteries with a cadmium content of more than 0.002% by weight has therefore been banned in the EU since December 2009. Device batteries intended for emergency or alarm systems including emergency lighting, military applications and for medical equipment are exempt from the ban.
Batteries intended for use in cordless power tools were exempt from the ban until December 31, 2016.

Heavy metals such as lead can have adverse health effects on humans, animals and plants and accumulate in the food chain and in the environment. If they enter water and accumulate in fish, for example, the heavy metals can enter the human body indirectly via the food chain. Lead can have a damaging effect on various organs and the central nervous system. It is deposited in the bones and can disrupt biochemical processes in the body. It is also highly toxic to aquatic organisms.
Lead may be used in batteries. If they contain more than 0.004 percent lead by weight, they must be marked with the symbol "Pb"(Latin plumbum "lead") so that consumers can recognize them as containing heavy metals. In addition, lead-acid batteries are always marked with the symbol of the crossed-out trash can, which indicates that they must not be thrown away in the household trash but must be disposed of.
Lead battterie
(Pb,VRLA,AGM)
Lead acid batteries (Pb, VRLA,AGM) are rechargeable secondary batteries.
Often the battery consists of several 2 volt battery cells, connected as 6V or 12V systems on the market.
Each separately consists of the positive electrode formed by lead dioxide (PbO2) and a negative lead electrode ( Pb) and the electrolyte as a conductor.
In the first charging phase, lead batteries are charged with constant current. Once a certain state of charge has been reached, further charging takes place with constant voltage.
The further development of lead batteries has led to encapsulated designs in which degassing takes place via a pressure valve and in which the liquid sulfuric acid is bound. This design is called Valve Regulated Lead Acid ( VRLA). There are two different VRLA designs: the Absorbent Glass Mat ( AGM), in which a glass fiber fleece is impregnated with the sulfuric acid, and the gel battery, in which the acid is bound in a gel.
