Safety is the biggest concern in all lithium ion batteries. The thermal runaway of working materials in lithium ion battery system as found with common used battery materials that the no return temperature TNR was calculated is around 75DegC and the self-accelerating decomposition temperature (SADT) is 66.5DegC. So, most lithium-ion battery fires and explosions come down due to a problem of short circuiting. This happens when the separator fails and lets the anode and cathode touch. And once those two get together, the battery starts to overheat and gets augmented to catch fire with chemicals of electrolyte.
As the physical property of Lithium is known it will need a complicated metallurgical alloying with other metals to exceed 1000 Kw/L. This will increase its cost and bring other side effects. Recently BMW experimented various cathode materials and three different anode materials. They found that the energy density gains from using next-generation cathode materials are limited, unless lithium metal is used as the anode. Main reason for this limitation is that higher capacity cathodes need correspondingly thicker anodes to hold the increased amount of lithium, drowning out some of the benefits of the cathode improvement. This exposes that Lithium ion batteries with a new alloyed metal will be more complicated.
The major bottleneck is its usage cycle. A next gen lithium Ion battery will be extensively costlier to exceed 5000 cycles.
By year 2025 there will be 30% short supply to demand of lithium if the present trend continues.
A dependency on Cobalt and Nickel is the major flop side. The improvised Lithium Ion batteries even extending its dependency on other pricey metals.

The present rechargeable batteries in automotive and energy storage are primarily lithium ion batteries with liquid electrolyte. There are several chemistries and metallurgical combinations of Lithium ion batteries which are pre dominant.
The major concern on Lithium Ion batteries are categorized in below five aspects. All variants of Lithium ion batteries including the upcoming Lithium Metal and solid state batteries too are victim of it.
Our immense research and experiments with an alloyed Aluminum Ion battery had provided an immense encouraging result. Aluminum is predominant easily available most used electrical conductor. Its electrochemical properties are very conducive. Years of research brought us closer to find a best fit rechargeable battery of world. There will be three variants of batteries where in couple of years we will provide an all solid aluminum rechargeable battery with energy density exceeding 1500 WH/L and capacity exceeding 600 WH/KG. Same will be remarkably cheaper to Lithium Ion batteries and will provide 3X charge-discharge cycles.
