Energy-dense Lithium-ion battery tend to explode more violently by wholesaleehop.com.au

May 31, 2011 - PRLog -- Leyden Energy constructed a new type of lithium-ion battery that it claims has an energy density of 225 Wh/kg, nearly twice that of typical lithium-ion batteries, which is usually less than 120 Wh/kg.

It said that it was able to manufacture them like this safely due to the fact that they can be operated at high temperatures without breaking down or exploding. More energy-dense lithium-ion batteries tend to explode more violently and are hence more dangerous than traditional ones, but they provide electric vehicles with a longer driving distance per charge.

Lithium-ion battery explosions are not common, but the fact that they can is a concern to many people… and it would have a pretty bad effect on the public perception of EVs  if people saw them exploding when they shouldn’t.

This type of battery is constructed with a graphite current collector and the sodium imide in the electrolyte. The current collector is made of graphite because a traditional aluminium one would be corroded by the sodium imide.

Energy density is actually a financial problem for electric vehicles due to the fact that a better energy density translates into a reduced number of batteries required, hence reducing the cost of the vehicles significantly (since the batteries account for an enormous fraction of their cost). A breakthrough in energy density like this, if true and without drawbacks, could mean great news for EV companies and EV lovers.

The new product suite that has been introduced includes 18650 cylindrical cells, pouch-style polymer cells and lithium-ion battery packs with high power. The pouch-style polymer cells are used for smaller consumer electronic devices like PCs tablet computers and the cylindrical cells are used for custom-designed hand-held devices and consumer electronics applications. The high-power batteries are used for sustainable energy management systems and EVs. The next-generation lithium-ion batteries of Leyden Energy undergo thorough testing to make sure that the products are compliant with RoHS, UN and UL safety standards.


The high energy density and superior thermal properties of the Leyden Energy’s batteries makes them ideal for EVs and consumer electronics applications. Also, the durability of the products is suitable for harsh environments in wind and solar energy generation.
