小米正式推出龙甲电池及配套的"小米龙甲电池安心保障计划"1。该电池由小米与中创新航、欣旺达联合打造1，具有远超国标的结构、热、电气和大数据安全标准1。
在结构安全方面，电池底部耐受撞击标准达到25mm撞击头、500J能量，远超国标30mm撞击头和150J能量标准1。热安全性能突出，在55℃高温、满电条件下单电芯热失控后依然无热蔓延、不起火、不爆炸1。电池的信息采集频率达到国标的10倍，数据量达到国标的3倍1，电芯循环寿命远超国标1000次循环后容量保持率≥80%的要求1。
保障计划为用户提供双重保障1。因原厂电池质量原因导致自燃且车辆达到报废条件时，用户可获得同等配置新车补偿1；因电池碰撞起火，补偿车损险保单额与保险实际赔付金额的差额1。这两项保障均为终身有效1。
Xiaomi has officially introduced its Longjia battery and the accompanying "Xiaomi Longjia Battery Peace of Mind Protection Plan," developed jointly with China Creation New Energy and Xinyangda 1. The battery meets safety standards significantly surpassing national benchmarks across structural, thermal, electrical, and data-driven safety dimensions 1.
The protection plan provides lifetime coverage against battery spontaneous combustion and collision-related fires 1. In cases where the vehicle reaches write-off conditions due to spontaneous combustion caused by original battery quality issues, owners receive compensation equivalent to a new vehicle with the same configuration 1. For collision-related fires, the plan covers the difference between the comprehensive insurance policy limit and the actual insurance payout 1.
The Longjia battery demonstrates enhanced durability and safety performance compared to national standards 1. The bottom impact resistance standard employs a 25mm impact head with 500 joules of energy, substantially exceeding the national standard of 30mm impact head and 150 joules 1. Under thermal safety testing at 55°C with full charge, individual cells remain stable without thermal runaway spread, ignition, or explosion 1. The battery collects data at ten times the national standard frequency, generating three times the data volume required by national benchmarks 1. Additionally, battery cell cycle life far exceeds the national requirement of maintaining 80% capacity retention after 1,000 cycles 1.
