Innolith: we will be the first with a battery with a specific energy of 1 kWh / kg
Swiss start-up Innolith AG has announced that it has begun work on lithium-ion cells that can reach an energy density of 1 kWh/kg. For comparison: the limit of our capabilities is now about 0,25-0,3 kWh / kg, and the first attacks on the regions of 0,3-0,4 kWh / kg are already underway. An energy density of 1 kWh / kg is the dream of most smartphone users, although not everyone knows about it 🙂 For example: the cells (batteries) of the most advanced modern phones today reach about 0,25-0,28 kWh / kg. If the energy density were four times greater, a cell with the same mass (and volume) could power a smartphone for four days instead of just one. Of course, such a battery would also require four ...
Mercedes doesn't want synthetic fuels. Excessive energy losses in the production process
In an interview with Autocar, Mercedes admitted that he wants to focus on electric drives. The production of synthetic fuels consumes too much energy - the best solution is to send it directly to batteries, according to a company representative. Synthetic fuels – an advantage that is a disadvantage Fuel derived from crude oil has a high specific energy per unit mass: for gasoline it is 12,9 kWh/kg, for diesel fuel it is 12,7 kWh/kg. For comparison, the best modern lithium-ion cells, the parameters of which are officially declared, offer up to 0,3 kWh / kg. Even if we take into account that on average 65 percent of the energy from gasoline is wasted as heat, from 1 kilogram of gasoline we still have about 4,5 kWh ...

Chalmers University and KTH have created a flexible structural link. Low energy density, but potential
Structural elements are a new trend in battery production. Elements that until now were only ballast are transformed into elements that serve as the basis of a battery or even a car. And it is in this direction that scientists from two well-known Swedish universities of technology have followed: Chalmers University and the Royal Institute of Technology (KTH). Flexible structural bonds due to composites. 0,024 kWh/kg now, 0,075 kWh/kg plans Structural bonds are sometimes referred to as "massless", but the term is not to be taken literally in the sense that is specific to particle physics. "Massless" cells in a car are simply cells that are not extra ballast because they act as skeletons, reinforcements, etc. - essential structures in a car. Created…
LG Chem announces new battery without modules (MPI). Cheaper and more spacious with the same dimensions
South Korean website Elec claims that LG Chem has completed its "Module Package Integrated (MPI) platform", which means just a battery without modules. The absence of this intermediate stage between the cells and the entire battery is claimed to provide a 10 percent higher energy density at the case level. Batteries without modules as the next step in the development of batteries Modules are physical blocks, sets of lithium-ion cells, enclosed in individual cases, which then consist of batteries. They provide safety - the voltage on each of the modules is at a human-safe level - and they make it easier to organize the package, but add their own weight to it, and their cases take up part of the space that can be filled with cells.
