What are the types of automobile batteries

Nickel cadmium battery
Nickel-cadmium battery (Ni-Cd) voltage: 1.2V Service life: 500 times Discharge temperature: - 20 ℃~60 ℃ Charge temperature: 0 ℃~45 ℃ Remarks: strong overcharge resistance.
Nickel metal hydride battery
Voltage of Ni-MH battery: 1.2V Service life: 1000 times Discharge temperature: - 10 ℃~45 ℃ Charging temperature: 10 ℃~45 ℃
Lithium ion battery
Li-ion battery voltage: 3.6V Service life: 500 times Discharge temperature: - 20 ℃~60 ℃ Charge temperature: 0 ℃~45 ℃ Remarks: weight is 30%~40% lighter than NiMH battery, capacity is more than 60% higher than NiMH battery. However, it is not resistant to overcharge. If overcharged, the temperature will be too high and the structure will be damaged=>explosion.
Lithium ion battery conductive coating coated with carbon aluminum foil:
The surface treatment of battery conductive substrate by functional coating is a breakthrough technological innovation. Carbon-coated aluminum foil/copper foil is to evenly and finely coat the dispersed nano-conductive graphite and carbon coated particles on the aluminum foil/copper foil. It can provide excellent static conductivity and collect the micro-current of active substances, which can greatly reduce the contact resistance between the positive/negative materials and the current collector, and improve the adhesion between the two, reduce the amount of adhesive used, and thus significantly improve the integrity of the battery.
Advantages of battery aluminum foil in lithium battery application
1、 Material description
Carbon-coated aluminum foil is made of conductive carbon-based composite paste and high-purity electronic aluminum foil by transfer coating process.
2、 Scope of application
Ø Power type lithium battery with fine particle active substance
Ø The cathode is lithium ferrous phosphate
Ø Ternary/lithium manganate with fine particles as cathode
Ø Used for supercapacitors and lithium primary batteries (lithium sulfite, lithium manganese, lithium iron, button type, etc.) instead of etching aluminum foil
3、 Performance effect on battery/capacitor
Ø Suppress battery polarization, reduce thermal effect and improve magnification performance;
Ø Reduce the internal resistance of the battery and significantly reduce the dynamic internal resistance increase during the cycle;
Ø Improve the consistency and increase the cycle life of the battery;
Ø Improve the adhesion between the active substance and the fluid collector, and reduce the manufacturing cost of the electrode;
Ø Protect the fluid collector from corrosion by electrolyte;
Ø Improve the high and low temperature performance of lithium iron phosphate battery, and improve the processing performance of lithium iron phosphate and lithium titanate materials.
Lithium polymer battery
Lithium polymer battery (Li-polymer) voltage: 3.7V Service life: 500 times Discharge temperature: - 20 ℃~60 ℃ Charge temperature: 0 ℃~45 ℃ Remarks: The improved type of lithium battery has no battery liquid, but it can be made into various shapes by using polymer electrolyte, which is more stable than lithium battery.
Lead acid battery
Lead acid battery (Sealed) voltage: 2V, service life: 200~300 times, discharge temperature: 0~45 degrees, charging temperature: 0~45 degrees Remarks: It is a general vehicle battery (it is connected in series with 6 2V to 12V), the service life of the water-free battery is up to 10 years, but the volume and weight are the largest.
