1. The safety of nickel hydrogen batteries:
The specific heat capacity and energy density of nickel hydrogen batteries are relatively low, with a melting point of up to 400 ℃. Therefore, when subjected to collisions, compressions, punctures, short circuits, etc., the battery temperature will not rise sharply, leading to spontaneous combustion; The electrolyte of nickel hydrogen batteries is a non flammable aqueous solution, which increases their safety.
The product quality control difficulty of nickel hydrogen batteries is low, and the yield rate is high, which helps to improve the safety of batteries; Nickel hydrogen batteries have shown high safety in long-term practical applications, such as Toyota's twin engine models, with almost no reported cases of spontaneous combustion.
2. The safety of lithium-ion batteries:
Due to the strong activity and high energy density of lithium-ion batteries, some types of lithium-ion battery raw materials are flammable. Once the temperature of the battery rises due to short circuits or other reasons, it may cause spontaneous combustion.
Lithium ion batteries may pose safety risks in the event of overcharging or overdischarging, such as thermal runaway or battery expansion; The safety performance of lithium-ion batteries is not only related to the material system and cell design, but also changes during use, especially under cyclic aging and storage aging conditions.
3. Security design:
The safety design of lithium-ion batteries includes protective measures against overcharging, overdischarging, short circuits, etc., as well as a battery management system (BMS) to monitor the battery status and ensure safety.
Although nickel hydrogen batteries have high safety, attention should still be paid to their charging characteristics, long-term storage characteristics, and safety protection under extreme conditions.
