Providing high-purity battery electrolyte to battery manufacturers

bringing to the world high-purity battery electrolytes made specifically for lithium batteries and helping battery manufacturers to increase their overall performance

Xiaowei offers high-purity lithium battery electrolytes for companies or research and development laboratories who want to enhance the electrochemical performance and safety stability of lithium batteries.

Our lithium ion battery electrolytes are mainly composed of lithium salt main salt, LiPF6, or LiFSI as well as several functional additives which are organic additives most commonly. The lithium batteries you manufacture can be used in various applications from consumer electronic battery products, electric vehicles, to energy storage devices.

The main role of high-quality electrolyte in batteries

1.Conduct ions to complete the charging and discharging process:

The principal job of the battery electrolyte is to serve as a channel for ion to move between the cathode and the anode of the battery that resulting in the lithium ions being a functional part. Lithium ions are released from the positive electrode that fills with ions to go to the negative electrode through the electrolyte. This whole process goes on while the lithium ions are embedded in the negative electrode material. On the other hand, the lithium ions are diverted from the positive electrodes, pass through the electrolyte to the positive electrodes and eventually the positive electrodes are entirely filled with ions. This ion movement process is the essence of the charging and discharging feature of the battery.

2.Maintain stable battery performance

The structure and quantity of the electrolyte battery go together with the lithium battery performance. The varying kinds of electrolytes can give various chemical reactions, which in turn will cause the change in battery voltage, capacity, cycle life, etc

3.Prevent battery plate corro

The electrolyte for battery generally holds a few corrosion inhibitors which are great at keeping the battery plate corroded. The corrosion inhibitor can be used as a layer that acts as a shield, as the plate’s surface is covered completely to shelter it from any contact with the electrolyte that prevents any corrosion reactions from occurring, thereby prolonging the battery life.

4.Heat is removed from the transformer

The battery has a power source that will provide a certain amount of heat during operation and the electrolyte in battery will cool it. With its high thermal conductivity, the electrolyte can effectively dissipate the heat generated within the battery to the surrounding environment, thus ensuring that the battery operates within a safe range.

5.Energy and power density are also increased in lithium batteries.

Of course, remember the electrolyte in lithium ion battery being an absolutely important part of the role of the enhanced cycle performance and energy density of batteries.

6.Provide high voltage and high specific energy

The electrolyte is a kind of battery essential thing in order to provide enough power and capacity such as high energy and high specific energy. Through several years of educated research and enhanced the characteristics of the electrolyte that will be readily applied to the battery enabling it to perform at higher voltage and of course, to meet the energy demand that is required by different manufacturers.

7.Protect battery safety

Some electrolytes have flame retardant properties, which can improve the safety of the battery. When the battery is overcharged, over-discharged, short-circuited or high temperature occurs, the flame retardant electrolyte can slow down or prevent the thermal runaway reaction inside the battery and reduce the occurrence of safety accidents.

Xiaowei helps lithium battery manufacturers achieve mass production of high-energy, high-power batteries by adjusting the composition and properties of the electrolyte and optimizing the mobility of lithium ions between the positive and negative electrodes.

F.A.Q.

The battery electrolyte is made in several steps, the solvent is made, purified, and the purified solvent will be mixed with LiPF6 and additives to make the desired lithium battery electrolyte.

Simply put, the electrolyte is used as the medium in lithium batteries, is the carrier for transporting lithium ions, and is the key to determining the performance of lithium-ion batteries.

The main components of electrolyte include electrolyte lithium salt, organic solvent and additives. Among them, the organic solvent is the main part of the electrolyte, and its performance is closely related to the solvent.

The optimal electrolyte should be able to transfer lithium ions between the positive and negative electrodes, but be insulated from electrons to ensure fast and efficient charging and discharging of the battery, and also need to take into account the requirements of electrical conductivity, high and low temperatures, low cost, and long life.

The ideal electrolyte should have the following advantages:

1) excellent conductor for lithium ions and insulator for electrons;

2) no side reactions on the electrode surface except for the migration of lithium ions;

3) no reaction with other battery components;

4) good chemical stability; safe and environmentally friendly;

The organic solvents used in the electrolyte in lithium batteries are mainly of the following types: carbonate esters, acid acid esters, ether organic solvents, sulfur-containing organic solvents.
