Custom Lithium ion Battery Pack
20 Years Focus On Lithium Ion Battery Pack Customization
Lithium polymer batteries have become a common choice for rechargeable batteries in smaller sizes. Compared with previous batteries, lithium polymer batteries are characterized by high energy density, miniaturization, lightweight and high cycle life. In terms of shape, lithium polymer batteries have the characteristics of ultra-thin, and can be made into batteries of different shapes and capacities to meet the needs of some products.
Battery Characteristics
1. The thinest value can reach 0.4mm;
2. Light weight and high capacity density are 15~20% more than that of aluminum steel shell battery;
3. It has aluminum - plastic film flexible packaging, laminated structure and good safety performance.
4. It has long cycle, low internal resistance, low heat and good power output;
5. Flexible product size can be customized according to customer requirements;
6. Green environmental products meet GB, UN, ROHS and other requirements.
Portable equipment, medical equipment, instruments and meters, communication products, digital products, etc. Such as portable printers, POS machines, walkie-talkies, GPS, camera, smart home, bluetooth devices, mobile communications and so on
Battery Cell Selection + PCM & BMS + Structure Design + Chargers
Cell Selection and Cell Quality Detection
Design of shape and internal structure
Electrical performance design：protection function, accurate power display, host communication, certification, battery set-making, charging
Charger design：External or built-in charger
Mid-term overall re-evaluation
First sample
Basic electrical performance test, and test under different environmental conditions
1、High Energy Density
Lithium polymer batteries are half the weight of nickel-cadmium or nickel-metal hydride batteries with the same capacity, 40 to 50% volume of nickel-cadmium, and 20 to 30% of nickel-metal hydride batteries.
2、High Voltage
A single polymer lithium battery has an operating voltage of 3.7V(average), which is equivalent to three nickel-cadmium or nickel-hydrogen batteries in series.
3、Good Safety Performance
The battery has aluminum plastic packaging, which is different from the metal shell of liquid lithium battery. Because of the flexible packaging technology, internal quality risks can be immediately shown through the outer packaging deformation. Once the safety risks ocurrs, the battery will not explode, but swell.
4、Long Cycle Life
Under normal conditions, lithium polymer batteries can be charged and discharged more than 500 times.
5、No Pollution
Lithium polymer batteries do not contain harmful metals such as cadmium, lead or mercury. The factory has passed ISO14000 environmental system certification, and the products comply with the EU RoHS directive.
6、No Memory Effect
Memory effect refers to the phenomenon that the capacity of nickel-cadmium battery decreases during the charging and discharging cycle. Lithium polymer batteries do not have this effect.
7、Fast Charge
Lithium polymer batteries can be fully charged in one to two hours using a constant current and constant voltage charger rated at 4.2V.
8、Complete Model
Complete models, capacity, large size range can be designed according to customer needs. Single cell thickness can be 0.8 ~ 10mm, and capacity can be 40mAh ~ 20Ah.
