Of lithium battery and lead acid battery is analysed

The safety of more power lithium batteries ( Lithium manganese acid lithium, lithium iron phosphate) The safety of the material is different, lead-acid battery technology already quite mature, security is better than lithium battery. 2. Environment is not polluted, lithium-ion batteries and lead-acid battery is polluted by heavy metal lead. Therefore, the use of lead-acid batteries of the electric car is still in the environmental pollution. 3. Price comparison of the same capacity lithium battery is the price of the lead-acid battery on the market more than twice. This is the cause of the lithium ion battery electric cars more expensive. 4. The comparison of energy ratio and volume ratio and the energy of lithium battery quality than about 40% higher than lead acid battery. 5. Self-discharge rate on the comparison of lithium battery self-discharge less than 3%, lead-acid battery self-discharge 15 ~ 30%. 6. Life is now, general purpose rechargeable lithium iron phosphate is 1500 times, no recall, charging after 1500 about 85% of the storage, the lead-acid battery charging 500 times or so, can significantly reduce storage capacity, and recall effect is obvious. Therefore, lithium ion battery electric vehicles longer. 7. Voltage platform is lithium battery voltage is greater than 3 v, v lead-acid battery is greater than 2. 8. Discharge characteristic is simpler to say that under the condition of the battery capacity is the same, lithium battery under the condition of high current discharge of electricity about 30% more than lead-acid batteries. 9. Durability strong lithium battery durability, power consumption is slow, charge and discharge more than 500 times, and has no memory, usually 4 - service life For five years. Depth of the depth of the lead-acid battery charging and discharging is in commonly 400 times less than, recall and service life of about two years. If you use is not in order to protect the lead-acid battery, it is important to note the battery water consumption is less, in use do not generally need to increase the distilled water. In terms of durability, the lithium battery has good shock resistance, in the case of a fully charged battery is fixed, safety cell was shock for 1 hour, the amplitude of 4 mm, frequency of 16. 7 hz, no leakage, battery without inflation and burst, open circuit voltage is normal; Good overcharge resistance, 25 ℃, with rechargeable batteries 0. 1 ca filling 48 hours, no leakage, battery without inflation and burst, open circuit voltage is normal, capacity to maintain rate more than 95%; Resistance to high current, a fully charged battery discharge 2 10 ca ca 5 minutes or 5 seconds, fuse without conductive parts, appearance without deformation.
