What are the factors that affect the cycle life of lithium-ion batteries?
1. The ratio of positive and negative materials for lithium-ion batteries should be reasonable. Since the active materials of the positive and negative electrodes are fixed on the substrate by the binder, the long-term stability of the binder and the good mechanical properties of the battery can delay the decline of the battery life, so to improved the positive electrode material's chemical stability and thermal stability is one of the feasible methods to maintain battery life.
How to choose lithium-ion batteries correctly?
Large-scale energy storage: Generally, comprehensive factors such as environmental protection, service life, and floor space are involved. Generally, it is recommended to use lithium iron phosphate battery cells, especially large-capacity lithium iron phosphate batteries
What are the common positive and negative materials in the lithium ion battery industry ?
What are the common positive and negative materials in the lithium-ion battery industry? The main constituent materials of lithium-ion batteries include electrolytes, separator materials, and positive and negative electrodes. Cathode materials and anode materials are one of the key materials that determine the performance of lithium-ion batteries, and are also the main source of lithium ions in current commercial lithium-ion batteries. Their performance and valence have a greater impact on lithium-ion batteries.
Why the maximum voltage of lithium-ion batteries cannot exceed 4.2V ?
The voltage of a lithium ion battery is determined by the electrode potential. Voltage, also known as potential difference, is a physical quantity that measures the energy difference of electric charges in an electrostatic field due to different potentials. The electrode potential of lithium ion is about 3V, and the voltage of lithium ion batteries varies with different materials. For example, a general lithium-ion battery has a rated voltage of 3.7V and a full-charge voltage of 4.2V; while a lithium iron phosphate battery has a rated voltage of 3.2V and a full-charge voltage of 3.65V. In other words, the potential difference between the positive electrode and the negative electrode of a lithium-ion battery in practical use cannot exceed 4.2V, which is an element based on material and use safety.

Lithium battery assembly methods and principles and attention
Lithium battery assembly methods can be divided into two forms, one is the production and assembly of lithium battery manufacturers, and the other is the personal purchase of batteries for DIY assembly. In fact, many manufacturers' lithium battery assembly is mechanized and programmed. As everyone knows, the following are mainly about the DIY method of personal lithium battery assembly and some problems to be paid attention to.
How to detect the quality of lithium-ion batteries?
Batteries play a vital role in our lives. They are used to store electricity and power various electrical appliances. Especially lithium-ion batteries, they are used in a wide range and are often used in some small portable appliances, such as mobile phones. The battery is a consumable material, and it is often charged and discharged. No matter the battery is the best, it has a certain lifespan, and the price of lithium-ion batteries is higher than other batteries, so try to choose good quality lithium-ion batteries when buying, and the service life can be longer , Then how do we detect the quality of lithium-ion batteries?
