HOT THEN COLD – Established that lithium ion batteries degrade when subjected to rapid charges at room temperature, around 10 ° C, due to the formation of lithium metal plates on the anode that limit its capacity and can cause malfunctions, the researchers have moved to remedy the problem. The solution they have reached is to insert a thin sheet of nickel, with a thickness of one micron, between the electrode layers, able to transfer the charge uniformly to the battery and to heat it in less than 30 seconds up to the 60 degrees.
LONG DURATION – Is exactly heat is the "secret" to promote speed of recharge and duration. The excellent is obtained by heating the new batteries at a temperature of 60 ° C for 10 minutes and then cooling them rapidly until it returns to room temperature. This allows the "self-heating" batteries developed at Penn State to charge much faster. Moreover, practically all electric cars on the market are already equipped with a battery cooling system, which could easily be used even in the pre-recharge phase. According to the inventors, the new batteries can support 2,500 recharge cycles, which are equivalent to around 800,000 kilometers of autonomy.
