  What are the classifications of energy 18650 lithium rechargeable battery and what are their characteristics?

  Energy 18650 lithium rechargeable battery can be divided into nickel-based batteries, lead-acid batteries, flow batteries, ternary lithium batteries, sodium-sulfur batteries and other related types. In addition, their characteristics are that they can operate normally in a temperature environment of 30-60 degrees and have relatively low temperatures. Regions can also be used, etc. The relevant content will be introduced in detail below.

  1. Classification of energy 18650 lithium rechargeable battery

  1. Lead-acid battery

  It is a battery whose electrodes are mainly made of lead and its oxides, and the electrolyte is sulfuric acid solution. In the discharged state of a lead-acid battery, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead; in the charged state, the main components of the positive and negative electrodes are both lead sulfate.

  2. Nickel battery

  Nickel metal hydride battery is a kind of battery with good performance. The positive active material of the nickel-hydrogen battery is Ni(OH)2 (called NiO electrode), the negative active material is metal hydride, also called hydrogen storage alloy (the electrode is called hydrogen storage electrode), and the electrolyte is 6mol/L potassium hydroxide solution.

  3. Lithium battery

  "Lithium battery" is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. . With the development of science and technology, lithium batteries have now become mainstream.

  4. Flow battery

  Flow energy 18650 lithium rechargeable battery are a type of device suitable for stationary large-scale energy storage (power storage). Compared with currently commonly used secondary batteries such as lead-acid batteries and nickel-cadmium batteries, the power and energy storage capacity can be designed independently. (The energy storage medium is stored outside the battery), high efficiency, long life, deep discharge capability, and environmental friendliness. It is one of the preferred technologies for large-scale energy storage technology.

  5. Sodium-sulfur battery

  A sodium-sulfur battery is a secondary battery that uses metallic sodium as the negative electrode, sulfur as the positive electrode, and a ceramic tube as the electrolyte separator. Under a certain working temperature, the reversible reaction between sodium ions through the electrolyte membrane and sulfur results in the release and storage of energy.

  6. Ternary lithium battery

  Ternary polymer lithium battery refers to a lithium battery that uses lithium nickel cobalt manganate (Li(NiCoMn)O2) ternary cathode material as the cathode material. The ternary composite cathode material is made of nickel salt, cobalt salt, and manganese salt as raw materials. The proportion of nickel, cobalt and manganese can be adjusted according to actual needs. Batteries with ternary materials as the positive electrode are safer than lithium cobalt oxide batteries, but the voltage is too low. When used on mobile phones (the cut-off voltage of mobile phones is generally around 3.0V), there will be obvious The feeling of insufficient capacity.

  7. Lithium iron phosphate

  Lithium iron phosphate battery refers to a lithium-ion battery using lithium iron phosphate as the positive electrode material. The cathode materials of lithium-ion batteries mainly include lithium cobalt oxide, lithium manganate, lithium nickel oxide, ternary materials, lithium iron phosphate, etc. Among them, lithium cobalt oxide is the cathode material currently used in most lithium-ion batteries.

  2. Characteristics of energy 18650 lithium rechargeable battery

  1. The temperature range used is relatively wide, and it is generally required to operate normally in a temperature environment of -30-60 degrees.

  2. The battery has better low-temperature performance and can be used even in areas with relatively low temperatures.

  3. The capacity consistency is good, and the consistency is maintained when the batteries are used in series and parallel.

  4. Good charging acceptance ability. In unstable charging environment, it has stronger charging acceptance capability.

  5. Long life, reducing repair and maintenance costs, and reducing overall system investment.
