Battery Introduction

Lithium batteries are divided into lithium batteries and lithium-ion batteries. Cell phones and laptops use lithium-ion batteries, which are often commonly referred to as lithium batteries. Batteries generally use materials containing lithium as electrodes, is a representative of modern high-performance batteries. True lithium batteries are seldom used in everyday electronics due to their high danger. Lithium-ion batteries were first developed by Sony in Japan in 1990. It is a lithium ion embedded in carbon (petroleum coke and graphite) to form an anode (traditional lithium batteries use lithium or lithium alloy as anode). LixCoO2, LixNiO2 and LixMnO4 are commonly used as cathode materials, and LiPF6+Ethylene Carbonate (EC)+Dimethyl Carbonate (DMC) is used as electrolyte. Petroleum coke and graphite as anode materials are non-toxic and sufficient resources, lithium ions embedded in carbon, overcoming the high activity of lithium, solving the safety problems existing in the traditional lithium batteries, anode LixCoO2 in charging and discharging performance and life expectancy can reach a higher level, so that the cost is reduced, in short, the overall performance of lithium-ion batteries has improved. It is expected that lithium-ion batteries will occupy a large market in the 21st century.

Advantages of lithium-ion batteries

High operating voltage, lithium-ion battery operating voltage of 3.6V; high specific energy, is 1.5 times that of the JinHydrogen battery; long cycle life, the current cycle life of up to 1,000 times or more, in the low depth of discharge can be up to a few tens of thousands of times; self-discharge rate is low, the monthly self-discharge rate of only 6% ~ 8%, lower than the nickel-metal hydride batteries (15% ~ 20%); no memory; no pollution to the environment; able to be manufactured into any shape.

Disadvantages of lithium-ion batteries

Disadvantages: poor consistency of the battery monomer, large performance degradation after grouping, cycle life and safety is difficult to guarantee, high cost; in the overcharging or abuse conditions, lithium-ion batteries may fire or explosion, so there must be a special protection circuit, must pay attention to the battery grouping technology, research and development of more reliable thermal management system and battery management system and other technologies.

Characteristics of lithium-ion batteries

The charging voltage of lithium-ion battery cells must be strictly maintained at about 4.1V, and the charging current is usually limited to less than 1C. If the charging voltage exceeds 4.5V, it may cause permanent damage to the lithium-ion battery. Lithium-ion battery discharge current should not normally exceed 3C. discharging monomer voltage must not be less than 2.2V. battery voltage below 2.2V, it will cause permanent damage.

What are the characteristics of lithium-ion batteries

Lithium-ion batteries are batteries that use lithium metal or lithium alloy as the anode material and use a non-aqueous solution. The negative electrode of a lithium ion battery is a graphite crystal and the positive electrode is usually lithium dioxide. When charging, lithium ions move from the positive electrode to the negative electrode and are embedded in the graphite layer. When discharged, lithium ions are detached from the surface of the negative electrode within the graphite crystal and move to the positive electrode. Because the battery charging and discharging process lithium is always in the form of lithium ions, rather than in the form of lithium metal. Therefore, this kind of battery is called lithium-ion battery. Lithium-ion batteries have some of the following characteristics.
