We CTECHI Group is a leading lithium manganese dioxide battery, lithium iron disulfide battery,lithium sulfur dioxide battery and lithium iron phosphate battery manufacturer and exporter in China, we are not only focus on provide single cell but provide battery assembly and do OEM service for customers, CTECHI has captured 80 percent of overseas markets in the past 16 years with more than 2000 reliable customers in our customer management system, which has been being one of the leading enterprises with the most complete category in China's battery industry.
CTECHI has established a long-term stable cooperation relationship with numerous well-known branded batteries’ retailers and agents at home and abroad, we are sole agent of Panasonic, Energizer, Maxell, Sanyo, LG, Samsung, Sony etc and so some battery packs for customers, we focus on provide battery pack assembly and customer needed charger or power for local and foreign customer. This is our assembly workshops: www.szcpkd.com.
We also have supported plants to manufacturer 3V Li-MnO2 Primary Battery (Panasonic brand) , 3.6V lithium SoCl2 battery (XENO or SAFT brand) , 1.5V lithium battery (Energizer brand) ,1.2V NIM and NICD battery, 3.7V Lion battery ,3.7V Polymer battery and so on. We are not only committed to providing one-stop service from R&D, production , assembly to trade, and the battery solutions for small and medium-sized enterprises around the world; but also externally focus on the quality in order to change the international people’s impression of "Made in China".
Lithium batteries have been widely used at present, but they have obvious shortcomings. First, the source of lithium-containing materials is limited. Second, the current use of flammable liquid electrolyte in lithium batteries is flammable and explosive, and the safety risk is high. With the support of the Swiss National Foundation for Scientific Research, the Swiss Federal Institute of Materials, the University of Geneva and the Paul Schell Institute have jointly launched a scientific research project since 2015 to try to develop batteries using sodium magnesium instead of lithium, and have achieved phased results.
Survey results: Most students remove the battery when using external power supply. Only a few students do not remove the battery when using external power supply. Suggestion: In fact, whether the battery is removed or not, the contradiction mainly focuses on whether the battery is charged when using external power supply. It should be known that the number of charges and discharges of batteries is directly related to life. Generally, the number of charges and discharges set by lithium batteries is fixed.
1. Environmental protection. Because of the application of colloidal electrolyte, the environmental impact of the product in the process of production, use and recovery has been minimized. The plates are made of lead-calcium-tin alloy plates specially developed for mercury-free and cadmium-free, which meet the latest EU standards. 2. High battery capacity. 3. Strong charging acceptance. Nanocolloids and special alloys ensure good charging acceptance of batteries.
Advanced technology has also made great changes in our lifestyle, such as communications, when our parents in the sixties and seventies, they did not have mobile phones, usually using pagers to send messages. Later, there were mobile phones. At that time, mobile phones were very big, very heavy and inconvenient to carry.
