III. Core Performance Advantages
(1) Cycle & Storage Performance: Long-lasting and Low Loss
The cell has excellent charge retention and capacity recovery capabilities. The room temperature charge retention rate is ≥96% and capacity recovery rate is ≥97% after 28 days at 25℃/100% SOC; the high temperature charge retention rate is ≥95% and capacity recovery rate is ≥96% after 7 days at 55℃/100% SOC.
It exhibits excellent high-temperature cycle performance: retaining more than 80% capacity after 1500 cycles at 45℃ and 1000 cycles at 55℃, and even up to 2500 cycles at room temperature (25℃), which is far superior to ordinary lithium battery cells and greatly reduces replacement costs.
(2) High & Low Temperature Performance: All-climate Adaptation, No Regional Restrictions
The cell is specially optimized for high and low temperature environments and can maintain stable capacity output at different temperatures: discharge capacity ≥90% of initial capacity at 0℃, ≥85% at -10℃, ≥80% at -20℃, and even retains ≥65% of initial capacity at extreme low temperature of -30℃, perfectly suitable for low-temperature northern regions and harsh outdoor environments; no attenuation in high-temperature discharge at 60℃, meeting the needs of high-temperature working conditions.
(3) Rate & Power Performance: Medium Rate Adaptation, Excellent Pulse Capability
As a medium-rate cell, it has outstanding pulse power performance: the maximum 30s pulse discharge power reaches 280W (rate 5.5C) at 25℃/100% SOC, and the maximum 10s pulse discharge power reaches 306W (rate 6.0C); the pulse feedback power is also excellent, with the maximum 10s pulse feedback power of 219W (rate 4.0C) at 25℃/0% SOC, which can realize rapid energy recovery and adapt to the instantaneous power demand of power equipment and the charge-discharge switching demand of energy storage equipment.
(4) Safety Performance: Multiple Tests, Extreme Reliability
The cell has passed the complete set of original factory safety tests of Gotion High-Tech. After tests such as overcharge, overdischarge, external short circuit (line resistance ＜5mΩ), heating at 130℃, crush (maximum pressure of 100kN) and temperature cycle at -40~85℃, all meet the judgment criteria of no ignition and no explosion. At the same time, a complete fault threshold is set (overvoltage alarm 3.8V, undervoltage alarm 1.8/2.0V, high temperature alarm 55/60℃), providing double safety guarantee for equipment use.
VI. Application Scenarios
– Industrial/civil power equipment such as low-speed new energy vehicles, electric forklifts and AGV trolleys
– Portable energy storage power supplies, household energy storage and small industrial and commercial energy storage systems
– Medium-rate electrical equipment such as electric tools and garden machinery
– Special power supplies such as on-board auxiliary power supplies and marine backup power supplies
– Supporting of power battery packs for new energy vehicles (used in single cell/pack)
– Long-term power supply scenarios such as outdoor monitoring equipment and communication base station backup power supplies
V. Usage & Storage Notes
(1) Key Usage Notes
– Strictly follow the charge/discharge voltage range: the discharge cut-off voltage is not lower than 2.0V at ＞0℃ and 1.8V at ≤0℃; the maximum charging voltage does not exceed 3.65V (overvoltage of 3.8V will affect the cycle life)
– The charging strategy refers to the original factory step charge matrix, matching the corresponding charging current at different temperatures, and it is forbidden to charge beyond the maximum charging rate
– It is forbidden to mix new and old cells when assembling the battery pack, and to match with other models of cells/modules; ensure good insulation between cell shells when connected in series
– When placed in the vehicle/equipment, the height direction of the cell must be perpendicular to the traveling direction of the equipment; avoid excessive extrusion, impact and throwing during use
– Do not wear metal accessories when operating the cell, and do a good job of insulation treatment for terminal connection to prevent short circuit of positive and negative poles
(2) Standard Storage Requirements
– When not in use for a long time, store in a cool and dry environment with temperature ≤35℃, and keep the SOC at 30%~50%
– If the storage period exceeds 3 months, a complete charge and discharge cycle is required to prevent cell performance degradation
– Do not place the cell in direct sunlight, heat sources (＞60℃), microwave ovens/high-pressure vessels and other environments
– Do not wet or immerse the cell in water/sea water, and keep the storage environment away from moisture and corrosive gas
IV. Quality & Environmental Certification
– Enterprise Standard Certification: Compliant with Hefei Gotion High-Tech enterprise standard Q/GX 023-2023, formulated with reference to national/international standards such as GB/T 31484-2015, GB 38031-2020 and IEC62619-2017, and the whole product process meets the standard requirements;
– Environmental Compliance: Strictly follow the EU Directive 2015/863 and Battery Directive 2006-66-EC, the content of 10 RoHS restricted substances such as cadmium, lead, mercury and hexavalent chromium are all lower than the maximum limit (e.g., Cd ≤20PPM, Pb ≤40PPM), meeting the environmental requirements of international markets such as the EU for export;
– Original Factory Quality Control: The entire production process of the cell is controlled by Gotion High-Tech’s quality control system, with no defects such as scratches, cracks and electrolyte leakage on the appearance. All products have passed multiple tests such as capacity, internal resistance and appearance before leaving the factory to ensure that each cell complies with the original factory specifications.
