‌Lithium-ion Batteries and PE Battery Separators

PE batteries separators for lithium-ion batteries are important battery part which plays major role in lithium-ion batteries which has special functions and benefits. PE battery separator consists of principally from polyethylene (PE), chemical resistance is great and mechanical strength high, PE battery separator can continuously perform in lithium-ion batteries.

Main use of PE separator for lithium ion battery is to separate positive and negative electrode, keep internal short circuits out of the battery, and distribute electrolyte uniformly so that normal charging and discharging of the battery happens.

Good performance: PE battery separator is good at isolation the positive and negative electrodes of the battery, eliminate short circuit from direct contact, so the battery can be safe and stable. Superior electrolyte reactivity: The porous structure of PE battery separator lets the electrolyte freely pass through the separator and ensures the evenly distributed electrolyte inside the battery for good charge/discharge behavior of the battery. One-layer PE battery separator is especially applicable to produce ultra-thin separators less than 16um, so that the battery has a smaller volume and weight, and increases the energy density of the battery.

Method of manufacture: PE battery separator can be the internal part of lithium battery. It's primarily used to isolate the positive end of the battery, to prevent the two poles from touching one another and short-circuiting, and to allow lithium ions to flow through it during the discharge process. This is resistant to chemicals and mechanical wear and can stay seated while the battery is running. In lithium batteries, they are directly responsible for the safety, energy density and cycle life of the battery. PE is tested in various lithium batteries of all kinds due to its good physical and chemical characteristics. Not only can it effectively avoid short circuits in the battery but also help bidirectional electrolyte ions move during charging and discharging which will enhance the charging quality and cycle stability of the battery. Also, PE pore size fabrication process and design is also important in applying effect in lithium batteries. With perfect manufacturing, PE pore size with correct pore size, the distribution of pore size is also good and there are fewer defects which further enhance lithium batteries performance and safety.

Application: PE battery separator has a great performance and it is extensively applied in many types of lithium-ion batteries especially high energy density, long life and stable performance, such as new energy vehicle, energy storage system and so on.

• New energy vehicles: As the focus has been on low-carbon transportation, new energy cars have come under intense pressure. Battery power is provided by the li-ion battery which plays an essential role in new energy cars and PE battery separators which are an integral part of lithium batteries enable battery supply safely. It has high waveform and ionicity that make the batteries more energy dense and absorbent.
• Lithium-ion batteries: Lithium-ion batteries are mainly found in consumer electronics like cellphones, tablet computers and laptops. PE battery separators offer high energy density and long cycle life in these devices which make them last longer and use longer. Meanwhile, its thin layer architecture allows the product to have more leeway with the structural configuration of the product.
• Battery Backup System: Battery Backup System in the Renewable Energy scenario is an evergreen concept. Lithium battery and PE calculation can efficiently distribute the power grid load balance, the wind and solar power storage and discharge, and the parallel PE ensure stable operation over many filling cycles and the reliability and feasibility of the backup system.
• Tools & gardening tools: Lithium-ion batteries are widely tested in tools and gardening tools. These appliances demand the charging output speed and continuous output power of the battery, and the PE battery type can deliver higher requirement power density and less charging time to meet the requirements of the industrial and home use.
• Electric scooters & electric bicycles: With cities gradually electrifying, electric transport scooters and electric bicycles have slowly taken on their importance in short-distance travel. PE batteries can be used in these cars power batteries for long-lasting power and security. The energy dense perception can actually improve the speed of motion and user interface.
• Medical instruments: The use of lithium in medical instruments is rising mainly in portable medical monitoring devices and surgery instruments. PE batteries are durable and safe which makes them work fine for long time usage.
