Why does Toyota always use Ni-MH batteries?

The electrolyte used in nickel-metal hydride batteries is a non-flammable aqueous solution, and its specific heat capacity and electrolyte evaporation are relatively high, but the energy density is relatively low, which means that even if there is a short circuit and other abnormal conditions, it will not cause combustion. Ni-MH batteries are currently the most valuable batteries for commercial applications. However, Japanese companies have high and cautious requirements for mature and safe technology, which has led Toyota to use Ni-MH batteries. ●Low processing requirements benefit from the long development time of nickel-hydrogen batteries. Even if they are not as powerful as lithium batteries in terms of energy density, the requirements for safety protection and temperature control during processing of nickel-hydrogen batteries are lower than those of lithium batteries. Many. This is to ensure the quality while controlling the cost, why not do it? ●Excellent low-temperature performance Lithium batteries use organic electrolyte solutions, which will greatly reduce battery performance and life span in low-temperature environments. The performance is already deviated at zero degrees, let alone lower temperatures. Many of Toyota's hybrid vehicles are sold in low temperatures. Take the northern part of our country as an example. The nickel-metal hydride battery uses an alkaline electrolyte solution, and the operating temperature can be as low as minus 40 degrees. In comparison, the nickel-metal hydride battery will be better. ●High recycling value Ni-MH batteries do not contain highly toxic substances and are relatively environmentally friendly. Its key components are nickel and rare earths, which are difficult to recycle and have high recycle value. It can be basically all recycled and reused. It is of vital significance for sustainable development. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
