Titanium Foil Lithium Battery Collector

 

 

 

Advantages of composite fluid collection:

1. Energy density increase

PET/PP/PI polyester material is lighter, due to the difference in material density, PET composite fluid collector with the same thickness has a significant weight reduction effect compared with traditional copper foil, and has an obvious effect on improving battery energy density, which is conducive to improving the vehicle's driving range. Copper foil increased the battery energy density more significantly than aluminum foil, composite copper foil single cell decreased by 6.1% mass, aluminum foil decreased by 3.7%.

 

2, high security

The polymer is not easy to break, and even if it does, the copper layer is thinner than the traditional one, and the burrs generated during puncture are shorter. The strength of the 1-micron copper plating cannot reach the standard of piercing the diaphragm, reducing the risk of burrs penetrating the diaphragm and contacting the electrode;

 

The organic layer such as PET is non-conductive and has a low melting point, which is easier to fuse and realize the point break of the local current when the local short circuit occurs, and the PET layer and the flame retardant structure can provide infinite resistance when the large area short circuit occurs, so as to effectively avoid the thermal runaway of the battery. In principle, aluminum foil and copper foil are basically the same in solving the internal short circuit, and there is no big difference between the two.

 

3, low material cost

Traditional copper foil raw materials account for 70%+ of the cost, and the cost reduction space is limited. The substituted composite material is significantly lower than the metal price, and the theoretical cost reduction space is large. The single-flat cost of composite copper foil is greater than that of aluminum foil, and the cost of single-flat raw materials is reduced by more than 2 yuan. Due to the low quality of raw materials and single-flat materials, the absolute value of the single-flat raw material cost is small, and the range is above 0.3 yuan/flat.

 

4, small pollution

The traditional coating process includes sewage, metal wastewater and volatile waste gas, and the waste residue is almost worthless. The equipment has a large mechanical noise. Vacuum coating directly in the ion exchanger reaction no pollution, waste slag is a valuable metal slag; At the same time, a new pharmaceutical system is used to avoid cyanide and other highly toxic substances. Antioxidant organic antioxidant liquid is used, the antioxidant is directly dried, and the agent is recycled to avoid the emission of metal pollutants.

 

The role of the battery fluid collector is to carry the positive and negative electrode materials, and concentrate the current inside the battery, so that the current can output more stable and efficient energy. It includes collecting current and distributing current,Generally speaking, the collector fluid is made of metal materials with good conductivity such as copper, aluminum, and silver, which are connected to the positive and negative electrodes of the cell to form a complete circuit.

 

Collector thinning must be the future direction of development, its cost is low, but high efficiency.. Since the essence of the collector is an inactive material, and does not improve the battery capacity, so without affecting the normal charge and discharge of the battery and safety premise, extremely thin fluid collector can reduce weight, weight reduction advantages are:

 

1, reduce the resistance, increase the quality of the active substance contained in the unit volume of the battery, improve the battery energy density;

2, reduce copper raw materials, reduce costs.

 

 

With the continuous progress of technology and people's attention to energy conservation and environmental protection, lithium batteries, as a high-performance battery, have gradually become an indispensable way of energy supply in people's lives. In recent years, titanium foil current collector lithium batteries have attracted much attention as a new type of lithium battery technology. This article will focus on the principle, characteristics, and application prospects of titanium foil collector lithium batteries.

 

Titanium foil current collector lithium battery is a lithium battery structure that uses titanium foil as the current collector. In traditional lithium batteries, the performance of the battery is poor due to the large internal resistance of the electrolyte during the diffusion process inside the battery. Titanium foil collector lithium batteries can effectively reduce the diffusion path of the electrolyte, reduce the internal resistance of the battery, and improve battery performance by using titanium foil as the collector.

 

The preparation process of titanium foil collector lithium batteries is relatively simple. Firstly, cut the titanium foil into appropriate sizes, and then perform special treatment on the surface of the titanium foil to increase surface activity and improve the electrochemical performance of the battery. Next, assemble the treated titanium foil and positive and negative electrode materials separately to form the positive and negative electrode structure of the battery. Finally, inject the electrolyte into the battery, seal it, and charge it before use.

 

Titanium foil collector lithium batteries have multiple advantages compared to traditional lithium batteries. Firstly, due to the excellent conductivity of titanium foil, it can effectively improve the output power and charge discharge efficiency of the battery. Secondly, titanium foil collector lithium batteries can improve the cycling life and safety performance of the battery by reducing the diffusion path of the electrolyte and reducing the internal resistance.

 

In addition, titanium foil collector lithium batteries also have advantages such as small size, light weight, and low cost, making them suitable for various energy supply needs in various scenarios.

 

Titanium foil collector lithium batteries have broad application prospects in various fields. Firstly, in the field of mobile electronic devices, such as mobile phones and tablets, titanium foil lithium batteries can provide longer battery life and faster charging speed, meeting people's high energy needs for portable devices. Secondly, in the field of electric vehicles, titanium foil collector lithium batteries can provide higher energy density and longer range, promoting the popularization and development of electric vehicles. In addition, titanium foil collector lithium batteries can also be applied in energy storage systems, aerospace and other fields, providing solutions for energy supply issues in various fields.

 

Titanium foil current collector lithium batteries, as a new type of lithium battery technology, have excellent electrochemical performance and broad application prospects. With the continuous progress of technology, it is believed that titanium foil collector lithium batteries will be widely used in the future and bring more convenience and comfort to people's lives.
