In fact, the lithium battery is a disposable battery, and the lithium ion battery is a rechargeable battery!

Lithium-ion battery and lithium battery difference:
1. Lithium primary battery is also called lithium battery. It is made of metallic lithium as an electrode, which generates current by electron transfer and can be discharged continuously or intermittently. Once the power is exhausted, it can no longer be used because it can easily cause dendrite explosion. Widely used in electronic products, such as cameras with low power consumption. The lithium primary battery has a very low self-discharge rate and can be stored for 3 years. It can be stored under refrigerated conditions and will work better. It is a good idea to store the lithium primary battery in a low temperature environment.
2. Lithium-ion battery is also called secondary lithium battery. Charge and discharge are performed by transfer of lithium ions, and an oxide of a lithium-doped metal is mainly used as an electrode. The battery is characterized by high power discharge and long battery cycle life. Due to its low self-discharge rate, it can be stored at 20 ° C for more than half a year, and most of the capacity can be recovered.
Note: Lithium primary batteries are different from lithium ion batteries. Lithium battery can not be charged, charging is very dangerous!

The difference between lithium ion battery and lithium polymer battery

Lithium-ion battery, commonly known as “lithium battery”, is a kind of battery that uses lithium metal or lithium alloy as negative electrode material and uses non-aqueous electrolyte solution. It is the best integrated battery system at present. The negative electrode of the lithium ion battery is a carbon material. For example, the graphite positive electrode is a lithium-containing transition metal oxide such as LiMn 2 O 4 .

Advantages of lithium-ion batteries:

1. The working voltage is high. Lithium-ion batteries operate at 3.6V, which is three times the operating voltage of nickel-cadmium and nickel-metal hydride batteries.
It is higher than energy. The specific energy of lithium-ion batteries has reached 140Wh / kg, which is three times that of nickel-cadmium batteries and 1.5 times that of nickel-hydrogen batteries.
3. Long cycle life. At present, the lithium ion battery has a cycle life of more than 1000 times, and can reach tens of thousands of times at a low discharge depth, exceeding several other secondary batteries.
4. Self-discharge is small. The monthly self-discharge rate of lithium-ion batteries is only 6-8%, which is much lower than that of nickel-cadmium batteries (25-30%) and nickel-hydrogen batteries (30-40%).
5. There is no memory effect. It can be charged as needed without degrading battery performance.
6. No pollution to the environment. There is no harmful substance in the lithium-ion battery, which is a veritable “green battery”.

Lithium polymer batteries are a new generation of batteries that entered the market in 1999. A lithium polymer battery is essentially the same as a lithium ion battery except that the electrolyte is a solid polymer rather than a liquid electrolyte.
The polymer electrolyte material is a general film composed of a solution in which an oxide of a host polymer such as polyethylene is used as a non-movable solvent.

Advantages of lithium polymer batteries:

1. Can be made into any shape and relatively light. Because it does not contain heavy metals and has a plastic shell that prevents electrolyte leakage. 2. Good performance and safer. The solid electrolyte acts like a sealing gel and does not easily disintegrate naturally during charging.

Portable solaer generator composition and maintenance testing

In normal use, the battery generally has self-discharge phenomenon, so if it is not used for a long time, the energy will be lost, so regular charge and discharge are needed to prevent energy loss. Solar mobile power is defined as having the advantages of being portable and portable, and converting solar energy into electrical energy and storing it in a battery. The portable solar generator system consists of five parts: power input circuits such as main circuit, bypass, battery, AC/DC converter rectifier, DC/AC converter, inverter and bypass output switch circuit, and energy storage battery.便携式ups

Professional testing (inspection and testing) personnel can determine the quality of the battery by measuring the open circuit voltage of the battery. Take a 12V battery as an example. If the open circuit voltage is higher than 12.5V, it means that the battery has more than 80% energy storage. If the open circuit voltage is lower than 12.5V, it should be charged immediately.

In addition, if the open circuit voltage is lower than 12V, it means that the battery storage energy is less than 20%, and the battery may not work properly.

In addition, since the maintenance-free battery uses an absorbing electrolyte system, no gas is generated during normal use, but if the user uses it improperly, the battery is overcharged to generate gas. Will increase, therefore, will open the pressure valve on the battery, in severe cases, the battery will rise, deform, leak or even rupture.

All of the above phenomena can be judged from the appearance. If you find this, you should replace the battery immediately.

In addition to the above, a discharge test (TestMeasure) was periodically performed, the battery voltage was measured, and the appearance of the battery was visually inspected for deformation or expansion and leakage. You should also check the battery’s battery +, – the electrode is oxidized regularly; the battery terminals are loose. In addition, the longer the battery is used, the more intensive the maintenance, UHOTOSHOP can be used without delay. The best use of the battery is between 0 °C and 40 °C, avoid direct sunlight and keep it clean and ventilated.

Finally, it should be reminded that the person responsible for battery maintenance should perform battery maintenance under the guidance of a professional engineer, or directly ask a professional engineer for battery maintenance to avoid electric shock.

This is undoubtedly the improvement of the battery life of portable medical equipment powered by lithium batteries. Critical.

Portable medical wireless digital X-ray imaging equipment

Portable medical wireless digital X-ray imaging equipment has played an active role in the imaging market. Digital imaging devices have matured after many developmental obstacles, and have been freed from the cumbersome and difficult to use situation, becoming a lightweight device that fully meets the requirements of portable imaging.

In portable wireless mode, the relationship between image quality and efficiency is clearly visible. In the traditional computerized X-ray mode, technicians need to constantly move around and prepare a cassette for each patient to get the results. Most of the inspections take a few minutes to complete. However, since the technician needs to return to the departmental exposure cassette, the radiologist and the referral doctor will have 20 to 30 minutes of waiting time before getting the image. These images can be viewed by a doctor within 4 to 5 minutes using a portable UPS.

The development trend of portable UPS:

Portable UPS is gaining popularity in medical devices, and portable medical device power management solutions will become more and more mature. Highly isolated DC-DC power supplies that meet medical certification will be more popular. With the ever-increasing demands of power technology, the development prospects of portable UPS are unstoppable.
