Electric cell refers to a single electrochemical cell containing positive and negative electrodes, which is not used directly. It is different from the battery which contains protective circuit and housing, and can be used directly. Generally speaking, it is a battery that removes the shell, and the rest is called the battery cell.

An international team of scientists focusing on next-generation energy storage solutions recently demonstrated an environmentally friendly and low-cost battery with exciting potential. Compared with typical lithium-ion batteries, this new sodium sulfur battery design provides four times the energy capacity, which is a promising technology for energy storage in the future grid scale.

All lithium ion batteries, whether in the past or in recent years, including lithium polymer batteries, lithium iron phosphate batteries and so on, are very afraid of internal battery short circuit, external battery short circuit, overcharge these situations.

Electric energy is an indispensable form of energy in the development of modern civilization, so batteries have become an indispensable necessity in human production and life.

According to the foreign media The Verge, batteries sometimes explode. Those explosion videos are scary, but scientists and startups have been working hard to build safer batteries. They are improving the battery design and testing new materials, hoping to solve the safety problem once and for all. But every method seems to have a trap, and the most practical solution at present may be the most boring. There are three strategies to improve battery: avoid using flammable liquid as solid battery; Make the battery module fireproof; Modify the existing functional characteristics of the battery slightly. At least as far as batteries are concerned, this change may come
