Surprise! There Are Still These Differences Between Lithium Batteries And Lead-acid Batteries!

Lithium battery is a kind of battery with lithium metal or lithium alloy as cathode material and non-aqueous electrolyte solution. Lithium battery has the advantages of light weight, large energy storage, high power, no pollution, no secondary pollution, long service life, small self discharge coefficient and wide temperature adaptation range. It is an ideal vehicle power for electric bicycles, electric motorcycles, electric cars, electric trucks and so on.

1、 Lithium battery

Advantages:

1. The operating frequency of high operating voltage single battery is three times that of nickel cadmium nickel hydrogen battery.

2. The high energy density is 555h/kg higher than the energy density, that is, the material volume can reach more than 150mah/g (3-4 times more than Ni Cd, 2-3 times more than Ni MH), which is close to 88% of the standard deviation.

3. Long life cycle system - generally 500 times or more, or 1000 times or more, and up to 2000 times for lithium phosphate battery. On the small current charge and discharge of household appliances, the cycle of rechargeable batteries will improve the competitiveness of household appliances.

4. The operating temperature is -2545 ℃, and the improvement of electrolyte and positive potential of lithium battery is expected to extend to -4070 ℃.

inferiority:

1. Decrease - unlike other rechargeable batteries, the volume of lithium-ion batteries decreases, depending on the frequency and temperature of use. This reduction can be achieved by reducing the volume and adding internal resistance.

2. Utilization - about 1% of the original and new products are required for various reasons.

3. Overcharged battery is not allowed to be charged. Overcharged lithium-ion battery will be permanently fixed at lattice constant and cannot be released, which may lead to short battery cycle.

2、 Lead acid battery

Advantages:

1. In all normal operations, lithium battery electrolyte is not easy to leak from the rechargeable battery terminal or bushing.

2. Protection and protection are simple - because the chaotic system software of the steam organization converts steam into water, there is no need to discharge water during the use of VRLA rechargeable batteries.

3. Safe and reliable quality - excellent production process and strict quality automatic control system are selected to ensure the safe and reliable quality of VRLA battery. Operation voltage, volume and sealing line detection.

inferiority:

1. To prevent the rechargeable battery from directly touching the stainless steel container, acid-base and heat-resistant materials should be selected, or they may cause smoke or burning.

2. Sealing the rechargeable battery of the equipment in the machine equipment will enable the machine to be turned over.

3. Putting the rechargeable battery into high temperature, sun, furnace or electric locomotive will cause leakage, burning or cracking of the rechargeable battery.

1. Lead acid battery: lead acid battery (plexiglass) and lithium-ion battery made of lead, metal lead and metal oxide are made of sulfuric acid solution. Under the charge and discharge conditions of lead-acid batteries, lead dioxide is the primary component of positive cycle and lead is the primary component of negative cycle.

2. Lithium ion battery: lithium ion battery: secondary battery (rechargeable battery), whose operation mode is to convert lithium ion battery into positive phase and negative phase.

Lithium batteries are divided into lithium batteries and lithium batteries. Mobile phones and notebook computers are lithium-ion batteries, commonly known as lithium-ion batteries. Rechargeable batteries are generally made of lithium, which is the method of modern battery function. However, the practical lithium-ion battery is not used in the whole battery charging process. The lithium-ion battery is placed back and forth in two charging stages, and the lithium-ion battery is decoupled from the positive battery during charging.
