In order to cope with the normal operation of equipment even when it cannot be connected to the power grid at all times, the concept of batteries has been gradually developed and has grown rapidly in modern times.
As a popular type of battery at present, lithium battery has shown a good performance beyond the "predecessor".
Lithium batteries have the advantages of high single cell voltage, large specific energy, and long storage life ( up to 10 years ) , but they also have disadvantages such as voltage lag, poor safety, and high cost

Lithium-ion battery with new polymer electrolyte Lithium-ion battery with new polymer electrolyte
Lithium-ion batteries, which are widely used at present, will form lithium dendrites after repeated charging and discharging, which will shorten the battery life, cause hot spots and short circuits.
As the lithium dendrites increase, it is easy to pierce the internal structure of the battery.
, resulting in a chemical reaction between the electrode and the electrolyte, resulting in a safety accident .
Lithium-ion batteries, which are widely used at present, will form lithium dendrites after repeated charging and discharging, which will shorten the battery life, cause hot spots and short circuits.
Engineers from the University of Illinois have recently developed a solid polymer electrolyte to help manufacturers produce recyclable, self-healing commercial batteries
.
Researchers have previously tried to use solid materials such as ceramics and polymers as electrolytes for batteries, but the results are not satisfactory.
This time, a new network polymer electrolyte was selected, which can undergo an exchange reaction and exchange polymer chains.
The researchers tested the electrical conductivity of the new material, which they believe has the potential to be an effective battery electrolyte

The development potential of all-resin batteries is promising
The same news related to lithium batteries also recently announced that Japan's Sanyo Chemical Industry announced that its subsidiary will start building factories and plans to start mass production of all-resin batteries next year

.
The all-resin battery does not use metal as the electrode, but uses resin as the raw material for its material and structure.
It is reported that the battery capacity of this all-resin battery can reach more than 2 times that of traditional batteries, the battery life can be optimized, its production cost is reduced by at least 20% compared with ordinary batteries , and the safety risk is significantly reduced, even if external force is used.
Destruction and cutting will not cause fire, and thanks to the plasticity of the resin, the battery also has a high degree of freedom in shape
.
According to the forecast, the demand potential and market potential of this all-resin battery are very large, and it is expected to be used in electric vehicles (EV) and stationary batteries in the future.
With the development of the new energy vehicle industry, this kind of battery may be expected to be widely used.
