In recent years, many automakers have revealed plans to build electric cars based on solid-state batteries For example, "Fisker applied for a patent for a solid-state lithium battery, with a maximum life of 800km and a charge of 1 minute", "Volkswagen plans to develop a 1000km solid-state battery" and other news are common.
Lishujun, a famous lithium-ion battery expert in China, analyzed the spontaneous combustion of batteries to find the culprit that caused the fire Mr Lishujun said there was a high probability that an internal short circuit would cause a spontaneous explosion.
The life of nickel-metal hydride batteries is slightly longer than that of nickel-cadmium batteries, all of which are more than 5 years old The nickel-metal hydride battery memory effect is very small and can be ignored.
1, industry concept and definitionElectrodes are mainly made of lead and its oxides The electrolyte is a battery of sulfuric acid solution.
Although the market investment enthusiasm is not reduced, but because the profit model is not clear, charging pile operators are still on the road to growth, how can we break a new world?Recently, the "2017 Second Electric Vehicle and Charging Infrastructure Construction and Operation Summit Forum" was held in Beijing According to Dr.
In recent years, new energy vehicles have officially ushered in the outbreak period, the power battery industry chain is gradually transformed from policy-driven to market-driven From the perspective of market demand for power batteries, the number of devices installed in 2018 May no longer boom but tend to grow steadily.
