Lithium batteries are increasingly being used in simple electric bicycles. What is the difference between lithium batteries and lead-acid batteries? What is the correct charging method for lithium batteries, and what should be paid attention to when charging lithium batteries for the first time? Sha...

Primary batteryAs the name suggests, disposable batteries can only be used. When the chemical energy of the battery is converted into electrical energy for power supply, it cannot compensate for the original electrical energy through charging or other methods. Therefore, it will not be used again af...

Important performance indicators of lithium-ion batteries1. Battery capacityThe capacity of a battery is divided into additional capacity and actual capacity. The additional capacity of a battery refers to the capacity of the battery at 20 ℃; The amount of electricity that should be supplied when d...

Structure and principleThe olivine structured lithium iron phosphate inside the lithium iron phosphate battery serves as the positive electrode of the battery, which is connected to the positive electrode of the battery through a separator between aluminum foil and polymer to distinguish between pos...

Step 1: Raw materials1. Solution ProductionA) The mixing ratio and weight of PVDF (or CMC) and solvent NMP (or deionized water);B) Mixing time, mixing frequency, solution frequency (and solution surface temperature);C) Check the solution after production: viscosity (inspection), solubility (visual i...

What is lithium film technology? What are the performance requirements for the product?(1) Product classificationThe separator, positive electrode material, negative electrode material, and electrolyte are the most important components of lithium-ion batteries. The internal structure of lithium-ion...

Explain the importance of fast charging technology for lithium-ion batteriesLithium ion batteries are divided into two types of materials: positive and negative electrodes. We often discuss lithium iron phosphate and ternary materials, which are actually the positive electrodes of lithium-ion batter...

Experimental method for preparation of silicon carbon composite materials for lithium-ion batteriesWe use solution plasma treatment (SPP) to detect the composition of silicon CB composite materials. The results indicate that SPP method is an excellent method for preparing carbon black with medium to...

Methods to extend the lifespan of lithium-ion batteries in portable power banksMobile power banks, also known as mobile phone battery power banks, are composed of polymer batteries as storage units for power sources such as mobile devices. They are safer and more durable than ordinary lithium-ion ba...

1. Composition of lithium power lithium-ion battery protection boardLithium ion battery protection board is an integrated circuit board designed for the protection of lithium-ion batteries. The protection of lithium-ion batteries is determined by their own characteristics. Due to the material of the...
