A group of researchers in the united states have decrypted the design of lithium ion batteries and have included cuts along their electrodes in order retain its battery life during automobile accidents. This would help the manufacturers to tone down the materials that are used to resist batteries from mechanical damage in electric cars. The impact of damage caused by large batteries is much larger as against small batteries. This breakthrough would ensure that the battery gets broken down into a host of smaller batteries, thus, reducing the impact of the accident. It would also assist in reducing the expenses that go toward extravagant containers currently used to protect batteries.
Mechanism to Increase Battery Life
The electric and hydraulic cars are inducted with lithium batteries that are quite are but they also get disrupted on occasions. To combat the situation, the researchers have perforated the batteries alongside the electrodes, which will subsequently break the electrodes into smaller fragments when a crash occurs. This would divide the heat of the battery into the various fragments, thus, countering the inability of the entire battery to stand the high heat or voltage and preventing a short. The fragments can also regulate the high currents.
Mitigating Dangers from Battery Failure
The research is inspired by the idea that dangerous failures could be combated by allowing the battery to breakdown with smoothness and ease, without causing further danger. The researchers deliberately distorted a lithium ion battery to find that it functioned up to 93% accuracy. This would have been impossible in a standard battery. The slits made into the electrodes do not incur a very high cost because of which there could be future success in this regard.
The researchers still believe there is a long way to go and a number of test need to ensued before final judgements could be made.
