Lithium-ion Battery
The operating temperature of ordinary batteries ranges from -20°C to +50°C. Those working below -20°C belong to a low temperature environment, and those working above 60°C belong to a high temperature environment. 

Except for industrial application scenarios such as high-temperature boilers and high-speed motors, drilling High-speed rotation of exploration equipment in the underground will also produce a high temperature environment, the highest temperature may reach 200 ℃, the instrument used for monitoring and collecting data also needs to withstand high temperature batteries as a power source, and equipment exposed to the hot summer sun will also work at high temperatures Condition. 

At present, the advanced high-temperature lithium thionyl chloride battery technology is still in the United States GE, APS, Tadiran, German Sunshine and other companies. Chinese companies can currently achieve lithium thionyl chloride batteries with a maximum temperature of 165°C, 125°C and 150°C. It is also achievable, no matter how high the temperature environment is, it has not been successful, so high-temperature lithium batteries for MWD, LWD, PWD, RSM and other equipment below 165°C will appear as Chinese products. 

For high-temperature lithium-ion rechargeable batteries, it is known from the US Energy Technology Laboratory that the United States completed the research and development of rechargeable batteries for MWD projects in 2010, and China’s high-temperature lithium-ion rechargeable batteries are currently only below +80°C.

  • High temperature capability – lithium cells can be designed to withstand temperatures up to 165 °C.

  • Capability of withstanding extreme amounts of shock and vibration

  • Manufacturing process that ensures extremely high reliability and safety.

  • Assembly techniques specific for high temperature, high vibration, and high shock environments.


Nickel Metal (Ni-Mh, Ni-Cd) Battery

Nickel Metal (Ni-Mh, Ni-Cd) Battery

As a kind of rechargeable battery, nickel metal series batteries include nickel-hydrogen batteries, nickel-cadmium batteries, and nickel-zinc batteries. 

Each has its own characteristics. Because its voltage is close to or the same as ordinary carbon and alkaline batteries, it can be recharged repeatedly, providing a small Current, high current discharge performance, wide operating temperature range.

It began to be commercialized in the 1970s. Ni-MH batteries were widely used as power sources for mobile phones, small home appliances, airplane models, car models, and ship models. 

Ni-Cd batteries were used as power sources for emergency lights, power tools, and base stations. 

In 2008, more than 2 million Toyota Honda series vehicles used Ni-MH batteries as their hybrid power.

Most of the patented nickel-metal hydride battery technologies are in the United States, Japan, Switzerland, and other countries.

Engizer in the United States, Panasonic, and FDK in Japan have advanced nickel-hydrogen battery technology and products. 

They have established a complete channel network around the world. 

Most manufacturers in China and overseas manufacturers (Such as OVONIC in the US) obtain patent authorization to produce nickel-metal hydride batteries. 

At the same time, Chinese scientific research experts and engineers are also developing their own patents on nickel-metal hydride battery research. 

They also have their own patents in low-temperature or wide-temperature working conditions and high current discharge. 

Because nickel-cadmium batteries contain heavy metal cadmium, under the requirements of the European Battery Directive. In addition to the only emergency light field, other fields have been required to replace nickel-hydrogen batteries.

Because of its high voltage, nickel-hydroge batteries provide high-drain current discharge. They are used to replace nickel-cadmium batteries on power tools and require
