As the healthcare field continues to expand, it covers emerging technologies and advanced equipment . Many medical devices use lithium-ion batteries as a source of energy, and the quality and stability of these batteries are crucial. The normal operation of medical equipment is inseparable from reliable instrument batteries. If the battery quality is not up to standard or there are problems, it may cause the equipment to suddenly lose power, posing a serious life-threatening risk to the patient. Therefore, when manufacturing medical device batteries, you must not be careless, and you must strictly follow the standard operation to ensure that every battery is safe and reliable.
Advantages of lithium batteries over other batteries
1. Lead-acid battery
Although lead-acid batteries are mature in technology and inexpensive, they have low energy density, large size, heavy weight, and environmental pollution problems. In contrast, lithium batteries have high energy density, small size, light weight, and better environmental performance .
2. NiMH batteries
Although nickel-metal hydride batteries also have high energy density and environmental performance, they have a high self-discharge rate and need to be charged regularly to maintain power. Lithium batteries have a low self-discharge rate and are more suitable for scenarios where they are not used for a long time. In addition, the cycle life of lithium batteries is also better than that of nickel-metal hydride batteries.
3. The fuel cell
Although fuel cells have advantages such as high energy conversion efficiency and zero emissions, their technology is complex, costly, and storage and transportation of hydrogen pose safety risks, which limits their widespread application. Lithium batteries, on the other hand, are mature in technology and relatively low in cost, making them more suitable for large-scale production and application.
Lithium batteries are obviously competitive in terms of performance, cost, environmental protection, etc. With the continuous advancement of technology and the reduction of costs, the application areas of lithium batteries will be further expanded, bringing more convenience and possibilities to people’s lives.
Application scenarios of lithium batteries
As a new type of battery with high energy density, long life and environmental protection, lithium battery has a wide range of innovative applications in the field of medical equipment .
Lithium-ion batteries are mainly used in medicine for hearing aids, pacemakers and other non-life-sustaining devices. Using lithium-ion batteries to replace primary batteries in hearing aids can solve problems such as high cost, environmental pollution, and reduced hearing aid effect caused by voltage drop, and has broad application potential.
The application of lithium-ion batteries in medical equipment enables many monitoring instruments, ultrasound equipment and infusion pumps to be used far away from hospitals.
Characteristics of medical lithium batteries :
1. Better safety performance: For medical devices, safety comes first . Lithium batteries specially used for medical devices generally use 18650 lithium batteries or polymer lithium batteries , which are extremely safe.
2. Higher energy density ratio: Energy density is one of the important indicators to measure battery performance, which directly affects the battery’s endurance and usage time. Due to the smaller size of lithium-ion batteries, lithium batteries can store more energy at the same size.
3. Better cycle performance: The cycle life of lithium batteries is usually between hundreds and thousands of times, and their performance is completely superior to early lead-acid or nickel-metal hydride batteries.
4. Longer battery life: Because lithium batteries have a higher energy density ratio, they provide longer battery life than lead-acid or nickel-metal hydride batteries at the same weight.
5. Better high and low temperature performance: Medical equipment has high power and requires high stability of lithium batteries. Such as high temperature resistance, low temperature resistance, high working voltage, etc., so that it can operate normally under various environmental conditions. Medical lithium batteries (groups) can operate normally at -20°C, while lead-acid or nickel-metal hydride batteries can operate normally at a minimum of -10°C.
6. Wide operating temperature range: Medical lithium batteries operate in the range of -20°C to 60°C. Specially customized low-temperature or high-temperature lithium batteries can operate in the range of -40°C or 85°C.
7. The battery has a low self-discharge rate: The current lithium battery material system is mature, the production and manufacturing process is highly automated, and the product consistency is good, so it has a low self-discharge rate.
8. Shape can be customized: Lithium-ion polymer batteries not only have the excellent performance of liquid lithium-ion batteries, but also have the advantages of solid lithium-ion batteries that can be made into ultra-thin batteries of any shape and size . Due to the particularity of medical equipment, lithium batteries can be specially customized. The thickness and shape of the battery can be changed according to different medical equipment to meet the needs of use.
9. Green and environmentally friendly: Medical lithium batteries do not contain toxic and harmful substances such as lead, chromium, and mercury. At the same time, because the batteries must be well sealed, very little gas is discharged during use, and no pollution is caused to the environment.
With the continuous advancement of technology, lithium-ion batteries have become a star product in the medical equipment industry. They not only have the advantages of high voltage, high energy and long life, but also meet the mobility requirements of portable medical equipment.
Therefore, I recommend using Kingsener ‘s standard lithium battery. This battery is convenient for operators to carry out mobile operations indoors and outdoors, and provides continuous, efficient and stable mobile power supply for the normal operation of the equipment. The use of high-performance battery cells makes the entire battery have the characteristics of high energy ratio, light weight, small size, high cycle life, high safety and high consistency. The battery is very convenient to use and the original battery can be replaced directly on site.
