Since BYD launched the blade battery, it is committed to battery safety, and major enterprises have launched characteristic battery technology one after another.
What are their respective characteristics?
The blade battery is so named because it is shaped like a blade. Because it uses lithium iron phosphate material, and lithium iron phosphate material is inherently safer than ternary materials, so it already has advantages from the material point of view.
In addition, compared with the traditional battery of the same material, the long strip structure of the blade battery has a large heat dissipation area, which is accompanied by a long circuit and low heat generation capacity of the whole circuit. To sum up, if the calorific value is low and the heat dissipation performance is good, the probability of thermal runaway or spontaneous combustion is much lower.
The jelly battery is launched by Honeycomb Energy, the new force of the battery. Jelly battery is a kind of gel battery based on cobalt-free cathode material and electrolyte material, which not only has good electrical conductivity, but also can self-heal and flame retardant, which can prevent heat diffusion without reducing electrical performance.
Officials say the jelly battery can withstand acupuncture and high temperature experiments, and the results show that the jelly battery can not only withstand a high temperature of 150 degrees Celsius, but also achieve no fire, smoke and self-healing, but because it is still in the stage of secrecy, there is no live video of the experiment on Honeycomb Energy Battery Day.
The magazine battery was launched by GAC. It is understood that the magazine battery is not just a change in cell packaging, but a whole set of systems engineering, including the improvement of the interior of the cell, the technological innovation of the packaging mode, the new design of the heat dissipation mode, the thorough upgrade of the monitoring chip, and the rewriting of the battery management software.
The "magazine battery" increases the stability of the cell by innovatively covering the positive pole of the cell and adding repair agent and heat-resistant agent. even if the heat is out of control, the cartridge safety cabin will control the danger in the grid and stop the spread of spread. at this time, the rapid cooling system will quickly dissipate the temperature of the problem cell until it is extinguished. at this time, the rapid cooling system will quickly dissipate the temperature of the problem cell until it is extinguished.
In fact, the amber battery is a "no smoke, no fire, no explosion" battery launched by Lantu, a subsidiary of Dongfeng Motor. According to Lantu, the "three nothing" benefits from three points: cell three-dimensional thermal insulation wall design, battery safety monitoring and early warning model, battery PACK design.
Heat insulation wall technology is the core of Lantu battery thermal runaway without smoke, its principle is in the battery package, the use of super polymer thermal insulation flame retardant material to separate each cell, and separate three-dimensional package. Like Amber. Lantu's "three no batteries" are also called "amber batteries".
In addition to the battery insulation wall technology, at the software level, Lantu also carries out big data analysis and tracking of the battery based on the BMS cloud guard. There is also a "ball cage" battery PACK scheme. Lantu carried out five major designs for the battery structure: customized body protection, high-strength frame, pressure transmission, deformation energy absorption and battery double insurance.
In addition, there are Xinwanda's battery system does not catch fire, Bic's "out of control is still safe" battery technology, and so on, they work together to promote battery safety, is a practitioner of battery technology changing with each passing day!
