Which is better, a lead-acid battery or a lithium battery?
The electric car I purchased uses a lithium battery. My boss told me that this is basically the one used now. a longer lifespan. Charging is also fast. In fact, lead-acid batteries and lithium batteries each have their own advantages and disadvantages. The choice of battery depends on the application scenario and needs.
The advantages of lead-acid batteries are: low cost, mature technology, high safety and recyclability.
The disadvantages are: low energy density, high weight, slow charging speed and short lifespan.
Equipment such as golf carts and electric forklifts that require stable power supply for a long time can use it.
The advantages of lithium batteries are: a dHigh energy density, light weight, fast charging and long lifespan.
The disadvantages are: high cost, relatively low safety and non-recyclability.
Drones, submarines, smartphones, tablets, laptops, digital cameras, etc. all use lithium batteries as the main power supply device.
What is a lithium battery?
Lithium batteries are generally divided into 2 categories:
They are: 1. Lithium metal batteries generally use manganese dioxide as the positive electrode material, lithium metal or its metal alloy as the negative electrode material, and use non-aqueous electrolyte solutions. 2. Lithium ion batteries generally use lithium alloy metal oxides as positive; Electrode material. Batteries that usegraphite as the negative electrode material and use non-aqueous electrolytes. Lithium-ion batteries can be divided into categories based on their uses. 3C lithium battery is the battery used daily in our mobile phones, tablets, laptops, etc. Power lithium batteries are batteries used in new energy electric vehicles, drones and other products.
Finished batteries of 3C lithium batteries need to be tested before they can be used, mainly to test whether their performance and quality meet the qualification standards. You can choose high current shrapnel microneedle module as the connection module. Firstly, it can transmit large current, the current transmission is very stable in the range of 1-50A, and it has good connection function. be adapted to small steps. The minimum step value canreach 0.15 mm, which is a reliable solution; third, it has an average lifespan of up to 20W and can handle high-frequency testing.
Lithium battery is the abbreviation of lithium-ion battery
Using lithium oxygen compound as the positive electrode, a negative electrode material (graphite, etc.), and dissolved lithium. Battery composed of an organic salt solvent (LiPF6, etc.) and an electrolyte.
Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium-ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable.
Lithium battery is short for lithium-ion battery. As a new type of energy storage battery, it gradually replaces the traditional lead-acid battery.
The most common batteries in daily life are batscell phone batteries, electric vehicles and trams, as well as power tool batteries.
1. From appearance: cylindrical, square.
2. From the outsideThe shell materials are divided into: steel shell, aluminum shell, plastic shell, aluminum plastic film (soft packaging).
3. According to energy density: capacity type and power type.
4. Separated from the electrolyte: liquid lithium-ion battery, solid (polymer) lithium-ion battery.
5. From the perspective of positive electrode materials: lithium cobalt oxide (C), lithium manganate (M), ternary lithium (N), and lithium iron phosphate (F).
The 18650 cylindrical battery is commonly used, which is a cylindrical battery with a diameter of 18 mm and a height of 65 mm.
Notes:
First, lithium-ion batteries can be seen everywhere in people's lives, in various portable electronic products,Vehicle GPS, etc. Lithium-ion batteries have become the key to keeping these tools running. Keeping lithium-ion batteries properly charged and discharged can extend battery life. Keeping the lithium-ion battery power between 10% and 90% is beneficial to protect the battery. This means that when charging batteries of digital products such as mobile phones and laptops, it is not necessary to reach the maximum value.
If digital products equipped with lithium-ion batteries are exposed to sunlight or stored in hot cars, it is best to keep these products turned off because if the operating temperature exceeds 60 degrees Celsius, the lithium battery -ion will accelerate aging. Lithium battery charging temperature range: 0 ~ 45 degrees Celsius, lithium battery discharge temperature range 0 ~ 60 degrees Celsius.
Second, if the cell phone battery needs to be charged every day, the reason may be that the battery is defective or it is time to "retire".
For laptop owners, it is best to remove the battery if it is plugged in for a long time (the high heat generated by the computer while in use is not good for the battery of the laptop).
Third, under normal circumstances, 50% power is most conducive to the preservation of lithium-ion batteries.
