Lithium battery characteristics.lithium deep cycle marine battery price

　　High energy

　　Compared with energy refers to the energy of unit weight or unit volume. It is represented by whittering by energy than energy. WH is the unit of energy, W is tile, H is the hour; KG is a kg (weight unit), L is a liter (volume unit). Energy density is the standard for measuring a battery. The lithium battery has high storage energy density, which has reached 460-600Wh/kg, which is about 6-7 times that of lead-acid batteries.

　　2. Good safety performance and long cycle life

　　The reason for the unsafe battery with metal lithium anode is the multiple charging and discharge of the lithium -ion battery to change the positive structure of the lithium -ion battery to form a porous branched crystal. When the temperature is elevated, it has a severe inspiration response to the electrolyte, and the branch crystal is crystal crystal. It is safe to pierce the diaphragm and cause short circuits inside, and there is no such problem in the lithium battery, which is very safe. In order to avoid the existence of metal lithium in the battery, the voltage must be controlled when charging. For insurance, there are multiple safety devices for lithium batteries.

　　The lithium battery has no structural changes in the lithium ion insertion and dehydration on the cathode and anode during the charging and discharge process (in the process of insertion and dehydration, there will be some expansion and contraction) Stable, lithium branches crystal will not be formed during the charging and discharge process, which significantly improves the safety performance of the battery, while the cycle life is also greatly improved. The service life can reach more than 6 years. The lithium iron phosphate is a 1C (100%DOD) battery with a positive electrode, and it can be used by 10,000 times.

　　3. High rated voltage

　　The single operating voltage of the monomer is 3.7V or 3.2V, which is about 3 series voltage of 3 nickel -cadmium or nickel -metalized batteries, which is convenient for the battery power set; lithium batteries can use a new type of lithium battery pressure regulator technology to bring voltage voltage voltage Trow up to 3.0V for the use of small appliances.

　　Cassents such as graphite or oil coke instead of metal lithium instead of metal lithium as the negative electrode, which will reduce the battery voltage. However, because they are low in lithium batteries, the voltage loss can be reduced to a minimum. At the same time, choose the appropriate lithium embedded compound as the battery positive electrode, and choose the appropriate electrolyte system (determine the electrochemical window of the lithium battery), which can make the lithium battery have a high working voltage (-4V), which is much higher than the water-solution system battery.

　　4. Have high power tolerance

　　Among them, the lithium-iron lithium-lithium-lithium-ion battery for electric vehicles can reach the capacity of 15-30C, which is convenient for high-intensity to accelerate.

　　5. The self -discharge rate is very low

　　This is one of the most prominent superiority of lithium batteries. Generally, it can be less than 1%/20 of nickel -metalized batteries. The lithium battery adopts a non -hydraulic fluid system, and the lithium carbon material is unstable in thermodynamics in the non -hydrocephaly system. During the first charging and discharge process, the restore of the electrolyte will form a layer of solid electrolyte (SEI) film on the surface of the carbon negative surface, allowing lithium ions to pass but not allowed electronics to pass In a relatively stable state, it has a low self -discharge rate.

　　6. Light weight

　　The weight under the same volume is about 1/6-1/5 of lead-acid products.
